April 30, 1942: U-Boats Attack!

Thursday 30 April 1942

Soviet freighter Ashkhabad sinking, 30 April 1942 worldwartwo.filminspector.com

Battle of the Pacific: The Japanese put Operation Mo, the projected capture of Port Moresby, into gear on 30 April 1942. They send carriers, Shokaku, Zuikaku, and Shoho, now replenished and rested after the Indian Ocean raid, to start the operation from the fleet base at Truk (Chuuk Lagoon).

RAAF P-39 fighters flying over the Stanley Mountain Range strafe Japanese planes and installations on the north coast at Lae and Salamaua. They lose one P-39F (41-7128).

Two Consolidated PBY-4 Catalinas of Patrol Squadron 101 (VP-101), based in Perth, Western Australia, fly a hazardous, lengthy, and circuitous route to the Philippines. They rescue 30 nurses from Corregidor Island, the lone Allied position holding out in the region, without incident. Many nurses, however, still remain on the fortified island, along with thousands of trapped soldiers. All are suffering deprivations and constant shelling from the Japanese artillery on the mainland and bombing attacks.

US Navy submarine USS Greenling (SS-213) stalks Japanese ammunition ship Seia Maru off Eniwetok. It fires torpedoes four separate times today and tomorrow. However, the torpedoes are faulty (a common problem during this period due to faulty fuses). The chase continues into 1 May 1942 but, despite even attempting a surface night attack, cannot sink it.
Borger, Texas, Daily Herald, 30 April 1942 worldwartwo.filminspector.com
The Borger (Texas) Daily Herald headlines the Japanese capture of Lashio, Burma, in its 30 April 1942 edition.
Battle of the Indian Ocean: Having taken Lashio, the Japanese send troops north toward Bhamo on the Irrawaddy River. They encounter opposition at a bridge across the Shweli River at Manwing by troops of the Northern Shan States Battalion, Burma Frontier Force. This defensive force left Lashio when the Chinese departed on 29 April. It manages to hold up the Japanese there for several days.

The Chinese Sixty-Sixth Army, still a powerful force although levered out of Lashio, withdraws along the Burma Road into China via Kutkai and Wanting. The Chinese 200th Division, which is isolated to the south and finds the way back to China blocked at Lashio, turns in the other direction and heads for Maymyo (Pyin Oo Lwin) in the direction of Mandalay. While this sends them in the general direction of the remaining British forces, the ultimate goal is to return to China as well. Doing so, however, will entail a lengthy detour around the advancing Japanese forces.

The British, meanwhile, continue to prepare for the inevitable loss of Mandalay as they retreat. Engineers destroy the bridge at Ava, the former capital of Burma, near the confluence of the Irrawaddy and Myitnge rivers just south of Mandalay. Their ultimate fall-back position, of course, is across the border in India.

Eastern Front: The Soviet Lyuban offensive is generally defined as ending on 30 April 1942. In reality, this effort ceased posing a threat to the Wehrmacht weeks ago due to the German response Unternehmen Raubtier ("Operation Wild Beast") that encircled the large Soviet force. It is estimated that the Volkhov Front loses 308,367 (95,064 killed or missing) out of an initial force of 327,700 during the operation - which is comparable to the later German losses at Stalingrad. General Andrey Vlasov, commander of the 2nd Shock Army, remains trapped in the dwindling pocket to the west of the Volkhov River. He cannot leave it without orders from Stalin - who habitually does not give such orders to failed commanders and troops. In any event, the spring thaw ("Rasputitsa") has stopped almost all operations for the time being.

European Air Operations: After many days of relentless attacks, both the RAF and Luftwaffe take the day off from major attacks. RAF Bomber Command does send 24 Boston bombers on escorted raids against Le Havre and Flushing docks, the Abbeville railway yards, and Morlaix airfield. These are all common targets and the raids are accomplished without loss. This begins a period of several days without major RAF attacks, though subsidiary operations such as minelaying continue.
HMS Edinburgh after being torpedoed on 30 April 1942 worldwartwo.filminspector.com

Battle of the Atlantic: Today is a great day for U-boats in the Barents Sea, off the US coast, and near the United Kingdom.

The brewing confrontation in the Barents Sea heats up on 30 April 1942. Two Allied convoys - PQ 15 and QP 11 - are converging in opposite directions north of Norway and the Kriegsmarine and Luftwaffe are ideally situated to wreak havoc. The Germans begin attacking, with U-88 and U-436 attacking freighters but missing, but score few successes. The main forces have not been committed pending further developments by advanced units already in place.

U-456 (Kptlt. Max-Martin Teichert), on its fourth war patrol out of Kirkenes, begins the battle when it torpedoes and damages the Royal Navy cruiser HMS Edinburgh (13 deaths), which is escorting QP 11. Edinburgh was a late addition to the convoy escort and is hit soon after it arrives. The U-boat scores two hits, one in the forward boiler room and the other at the stern. Under half power, with the rudder and two of four propellers destroyed, Edinburgh heads back toward Murmansk scored by destroyers Foresight and Forester. Other ships leave Murmansk to aid the stricken cruiser, including British minesweepers Gossamer, Harrier, Hussar, and Niger, the Soviet destroyers Gremyashchy and Sokrushitelny, the Soviet guard ship Rubin, and a tug. 

While the cruiser does not sink (yet), its damage causes the Allies problems. The attack exposes more Allied ships to attack and reduces the convoy escort by three ships. The Kriegsmarine attempts to take advantage of this favorable change in circumstances by dispatching the three destroyers of Zerstörergruppe "Arktis" (Z7 "Hermann Schoemann" (KptzS Schultze-Hinrichs), Z24, and Z25), under the command of Kapitän zur See Alfred Schulze-Hinrichs, to attack QP 11 and finish off the Edinburgh. It will take them until the afternoon of 1 May 1942 to reach the convoy.

German heavy cruiser Admiral Scheer is spotted by RAF reconnaissance while warming up for a potential dash to the Arctic convoys from its base at Trondheim, Norway, 30 April 1942 (Naval History and Heritage Command NH 110804).
U-402 (Kptlt. Siegfried Freiherr von Forstner), on its third patrol out of St. Nazaire, torpedoes and badly damages Soviet freighter Ashkhabad south of Cape Lookout, North Carolina. The 47 crewmen abandon the freighter and are rescued by HMT Lady Elsa. The Ashkhabad remains afloat and naval authorities decide to salvage her. However, before tug USS Relief can make it to the location, two escorts (USS Semmes and HMT St. Zeno) scuttle Ashkhabad as a hazard to navigation.

U-552 (Kptlt. Erich Topp), on its eighth patrol out of St. Nazaire, torpedoes and sinks Canadian troop transport SS Nerissa In the Atlantic northwest of Ireland about 200 miles (320 km) from Liverpool. Topp is on the surface when he spots the transport approaching from the northwest and then stalks the ship for almost two hours. One of three torpedoes hits the Nerissa astern, and Topp soon closes to pump another torpedo into it. There are 84 survivors and 207 (124 passengers and 83 crew) deaths. The survivors are picked up at first light by HMS Veteran. The Nerissa is remembered as the only troopship to have Canadian casualties en route to England during World War II.

U-162 (FrgKpt. Jürgen Wattenberg), on its second patrol out of Lorient, torpedoes and sinks 8941-ton British freighter Athelempress about 180 nautical miles (330 km) east of Barbados. There are three deaths and 47 survivors, who are picked up by Norwegian freighter Atlantic.

U-752 (Kptlt. Karl-Ernst Schroeter), on its fifth patrol out of La Pallice, torpedoes and sinks 4956-ton Norwegian freighter Bidevind about 74 miles southeast of Ambrose Lightship in the Atlantic east of Delaware and south of Long Island. All 36 crewmen survive (three injuries). The wreck, at 190 feet (58 m), becomes a popular deep-dive site for advanced local sport divers.

U-507 (KrvKpt. Harro Schacht), on its second patrol out of Lorient, torpedoes and sinks 2881-ton US tanker Federal about 5 nautical miles (9.3 km) north of Gibara, Cuba. There are five deaths and 28 survivors, some of whom are picked up by a Cuban fishing trawler while others make it to shore in a lifeboat.

U-576 (Kptlt. Hans-Dieter Heinicke), on its fourth patrol out of St. Nazaire, torpedoes and sinks Norwegian freighter Taborfjell about 95 nautical miles (176 km) east of Cape Cod, Massachusetts. The ship is carrying unrefined sugar from Matanzas, Cuba. There are 17 deaths and three survivors, who are picked up by HMS P552.

Battle of the Mediterranean: The Axis air offensive against Malta continues on 30 April 1942. The Germans and Italians have averaged 200 bomber sorties over the island since Luftwaffe General Albert Kesselring began the offensive in March 1942. Today's attacks begin at 11:20 and continue throughout the day as usual. The Luftwaffe's rescue operations have become increasingly brave and a Dornier Do 24 flying boat is seen offshore rescuing a downed German pilot. While rescue operations under prewar agreements are considered humanitarian operations immune from attack, in reality, they have been deemed game since the Battle of Britain for alleged reconnaissance operations.
Hitler and Mussolini at Schloss Klessheim on 30 April 1942 worldwartwo.filminspector.com
Hitler and Mussolini at Schloss Klessheim for their two-day meeting at the end of April 1942 (National Digital Archives Poland).
Axis Relations: Adolf Hitler and Benito Mussolini continue their summit meeting at Schloss Klessheim in Salzburg, Germany. Hitler unleashes a monologue lasting an hour and forty minutes on the Duce covering a wide variety of military, economic, social, and philosophical topics but noticeably silent about the future Franco-Italian frontier and similar topics of particular interest to Italy. Hitler is quoted as saying "Soon the laughter of the Jews will fall silent forever," "The Aryan is the Prometheus of mankind," and "Violence is the mother of order and the source of all true greatness - I have restored to violence its true meaning." Anticipating the final collapse of the Soviet Union by the fall, he elaborates on his post-war plans, many of which revolve around social engineering.

The Salzburg meeting marks the first time at these conferences that Hitler talks about a definitive end to the war due to a decisive summer campaign in the Soviet Union. He convinces Mussolini to agree to send more Italian troops to the Eastern Front, but his plans for the Mediterranean that is of much more urgent concern to Mussolini are left vague. Hitler reveals the Wehrmacht, in conjunction with Italian forces, plans to invade Malta in Operation Hercules (Unternehmen Herkules), with a tenuous launch date of mid-July 1942. The plans have been approved but are on hold pending developments in North Africa.

However, Operation Hercules is a divisive issue within the German hierarchy. While local Wehrmacht commanders including Generals Albert Kesselring and Erwin Rommel, both in attendance, strongly support Operation Hercules, They believe it would secure the Mediterranean for Axis shipping (which has taken heavy losses from the Royal Navy). Luftwaffe boss Hermann Goering is concerned. He believes that invading Malta could turn into a near-disaster like the ultimately successful but costly paratrooper (Fallschirmjäger) invasion of Crete (Operation Mercury) in May 1941. Hitler himself is very hesitant about the operation for the same reasons and wants to focus on the Eastern Front. The operation is never launched.

It will be commissioned on 21 November 1942 after becoming the first submarine to use the mid-western waterways to reach New Orleans, LA. It has a distinguished career in the Pacific Theater of Operations (US Navy photo).
US/Vichy France Relations: US Ambassador to France Admiral William Leahy bids farewell to his Embassy staff in Paris before beginning the long journey back to the United States. No new ambassador is slated to replace him, effectively ending diplomatic relations. The U.S. Embassy will remain open, run by Charge d’Affaires Pinckney Tuck, until the landing of US troops in French North Africa in November 1942 ("Operation Torch").

US Military: Admiral Harold R. Stark assumes command of U.S. Naval Forces Europe. This is actually a demotion, as Stark has been Chief of Naval Operations since August 1939. Stark is under a cloud due to the losses at Pearl Harbor and eventually must face a court of inquiry over this with negative findings for him. However, Stark makes the best of a bad situation and oversees the buildup of US naval forces from his headquarters in London, culminating in the successful D-Day landings.

The US Navy commissions 35,000-ton battleship USS Indiana at Newport News, Virginia. She will serve primarily in the Pacific Theater of Operations and be decommissioned in 1947.

Two Vought SB2U Vindicator aircraft collide during training exercises off Sandy Point, Block Island. The two-man crew of one plane survives, the other two men (Ensign David Kauffman and Lt. (Jg.)  Howard Lapsley) perish.

US Government: The House naval committee rejects a bill to raise the statutory workweek from 40 hours to 48 hours, limit war profits, and freeze the status quo of open and closed workplaces for the duration of the war. This bill is likely in response to a recent US Supreme Court decision allowing reasonable profits from the manufacture of goods for the United States military during World War I. President Roosevelt is against the bill, which elicits strong passions on both sides.

Holocaust: In Dzyatlava, Western Belarus, German soldiers wake up resident of the Zdzięcioł Ghetto with gunshots. The Judenrat issues a statement from the German authorities that all Jewish residents are to assemble at an old cemetery on the fringes of the ghetto. Those who refuse are brought by force to that location by Germans and their local Belarusian and Lithuanian collaborators. After a typical Holocaust selection process where some victims are selected for execution based on age and gender, these roughly 1000 people, perhaps more, are marched to nearby Kurpiasz (Kurpyash) Forest and shot and buried know unmarked graves (about 100 are given reprieves based on documents they carried). Another similar massacre takes place on 10 August 1942 and subsequent days for a total of about 3000 victims or more. This is known as the Dzyatlava massacre and a plaque commemorates it.

Japanese Homefront: The Imperial Rule Assistance Association, which supports the government and its goals of his Shintaisei ("New Order") movement, dominates local elections. it wins 381 out of 466 seats.

American Homefront: Lieut. Gen. John DeWitt, head of the Western Defense Command, issues new evacuation orders for 5100 additional people of Japanese descent from Alameda, Contra Costa, and Los Angeles Counties. Evacuations will continue until 20 May 1942.

Film studio 20th Century Fox releases "My Gal Sal," a musical directed by Irving Cummings starring Rita Hayworth and Victor Mature. It profiles 1890s composer and songwriter Paul Dresser. The biopic is a typical mixture of reality and Hollywood artifice, with some of the songs having no connection to Dresser. The film features comedian Phil Silvers and Terry Moore (later girlfriend, maybe wife, of Howard Hughes and still alive as of this writing in 2021) in early roles.

April 20, 1942: The Operation Calendar Disaster

Monday 20 April 1942

Hitler's birthday 20 April 1942 worldwartwo.filminspector.com
A military parade in honor of Adolf Hitler's birthday organized by Reichskommissar Koch in Rovno, Ukraine on 20 April 1942 (Federal Archive B 162 pic-04246).
Battle of the Pacific: The Japanese high command is still furious on 20 April 1942 about the Doolittle raid and orders the massive Second Fleet, recently returned from its Indian Ocean Raid, to hunt down the American carrier task force. Nobody has any idea where the US ships are, and Admiral Nagumo aboard his own carrier, the Akagi, thinks they may be within striking distance of his ships near Formosa and attack them. The fact that the US Navy used land-based bombers in the attack further confuses the Japanese. Meanwhile, USS Enterprise and Hornet have long since departed the scene as they return to Pearl Harbor. The US high command, mirroring Japanese concerns, also remains deeply worried about a Japanese attack on the west coast.

In the Philippines, Japanese artillery continues to pound the last US island outpost of Corregidor. The Japanese have overrun US positions on Cebu and Panay, and US and affiliated Filipino garrisons throughout the northern and central Philippines have fled into the hills to operate as guerilla forces on Leyte, Samar, Negros, and Bohol.

Soviet freighter Turksib is wrecked in bad weather in the Unimak Strait, Alaska Territory. The USSR and Japan are not at war, so Soviet ships may pass more-or-less freely between their home ports and the United States, though they are subject to search for military goods by Japanese patrol vessels.

Battle of the Indian Ocean: Chinese General Sun Li-Jen, having successfully rescued trapped British forces on the 19th, continues attacking south toward the Yenaungyaung oil fields. The small Chinese force makes some progress and inflicts heavy casualties on the Japanese, but this success is only temporary and the Chinese soon begin retreating back to the north. The British 1st Burma Division that barely had escaped destruction due to the Chinese advance finds vehicles to take it north to Mount Popa.

Eastern Front: The spring thaw ("Rasputitsa") is rapidly increasing, causing extensive flooding and muddy conditions that make operations difficult. General Franz Halder notes in his war diary:

Curiously quiet. Enemy is seemingly anticipating a German red-letter day attack. Enemy propaganda. Good progress on the Lovat River. The gap has been almost closed. Consolidation of the situation on the Volkhov River.

The two operations that Halder mentions, on the Lovat and Vokhov rivers, are of utmost importance to both sides as large numbers of troops are at risk. The former is the relief operation to rescue the huge German forces trapped at Demyansk and Kholm, and the latter is a large Soviet force including the Second Shock Army that is trapped west of the Volkhov. While the outcome of both operations has been in doubt for months, the Germans gradually are gaining the upper hand in both sectors.

The Soviet Stavka (high command) officially ends the Rzhevsk-Vyazma Operation and orders forces in the area over to the defensive. This follows a partially successful breakout of trapped Soviet forces in the area east of Smolensk. The operation was a failure in its objective to encircle and destroy large Wehrmacht forces, but the Soviets claim that it succeeded in forced German forces back 100-250 kilometers.

European Air Operations: There are no operations today due to some very thick ground haze. A circus over a French port is briefly planned but scrubbed at 12:15 local time.

Battle of the Atlantic: U-572 (Kptlt. Heinz Hirsacker), on its fourth patrol out of Brest, torpedoes, and sinks 7164-ton British freighter Empire Dryden about 240 nautical miles (440 km) northwest of Bermuda. There are 25 deaths and 22 survivors, who are picked up by the US freighter City of Birmingham.

U-752 (Kptlt. Karl-Ernst Schroeter), on its fifth patrol out of La Pallice, torpedoes, shells, and badly damages US freighter West Imboden about 200 miles off the Nantucket lightship. The freighter was an easy target due to an accidental fire in its stack that gave away its position. The U-boat captain has a conversation with the survivors in their lifeboats and says "That's good" when told there have been no casualties. West Imboden later sinks.

U-654 (Oblt. Ludwig Forster), on its third patrol out of Brest, torpedoes and sinks 4569-ton Swedish freighter Agra about 280 nautical miles (520 km) northwest of Bermuda. There are six deaths and 33 survivors, who are picked up by Norwegian freighter Tercero. Torpedoing neutral shipping obviously is improper, but all ships are transiting in blackout conditions and it is largely impossible to tell neutral shipping from legitimate targets.

U-654 also torpedoes and sinks 6176-ton US freighter Steel Maker about 350 nautical miles (650 km) east of Wilmington, North Carolina. There are one death and 47 survivors, who are rescued by British freighter Pacific Exporter and USS Rowan. The one crewman rescued by the Rowan is in the water until 18 May 1942.

U-109 (Kptlt. Heinrich Bleichrodt), on its fifth patrol out of Lorient, torpedoes and sinks 5719-ton British freighter Harpagon about 150 nautical miles (280 km) northwest of Bermuda. There are 41 deaths and eight survivors, who are picked up by Argentinian freighter Rio Diamante.

U-154 (KrvKpt. Walther Kölle), on its second patrol out of Lorient, torpedoes and sinks 5587-ton Canadian freighter Vineland in the mid-Atlantic. There are 34 survivors and one death.

Royal Navy submarine HMS Trident torpedoes and sinks 5386-ton German freighter Hödur northwest of Namsos, Norway.

Royal Navy destroyers Cotswold and Quorn, operating as escorts for Convoy FS 80 in the North Sea, hit mines off Aldeburgh, Suffolk. Quorn (two deaths) is towed by patrol sloop Shearwater to Chatham and requires 17 weeks of repairs, while Cotswold (five dead, 23 wounded) is towed Shotley Spit and beached. Refloated later, Cotswold re-enters service on 8 May 1943.

British 1498-ton freighter Plawsworth and Belgian 1829-ton freighter Vae Victis, members of Convoy FS 80, also hit mines and sink in the North Sea off Aldeburgh, Suffolk.

Swedish 569-ton coaster Arete hits a mine and sinks in the Danish Great Belt strait. There are four deaths.

German 470-ton trawler/minesweeper M 4006 Neuwerk hits a mine and sinks in the English Channel off Morlaix, Finistère, France.

Battle of the Mediterranean: Aircraft carrier USS Wasp (CV-7) flies off 48 Spitfire fighters of RAF No. 601 and 603 Squadrons to land in Malta, which has had no operational fighter cover recently. The Wasp's Grumman F4F Wildcats provide air cover. Operation Calendar has resulted from a personal request from Winston Churchill to President Roosevelt for the use of a US carrier for this purpose.

The Luftwaffe has been alerted to the joint US-British operation and times an air raid to coincide with the landing of the Spitfires at Malta's Ta'Qali airfield. The RAF fighters, low on fuel after their shuttle flight, cannot defend themselves and must land immediately, leaving them vulnerable. The German bombers, facing no air opposition, destroy most of the incoming fighters immediately and virtually all of them within days (some sources say within two days, others within four days).

The British military command and Churchill are aghast at this disaster. They set in motion plans to replace the island's longtime governor, Lieutenant General Sir William Dobbie, who blames the failure on the intense bombardment that the island has faced over the past month from German General Albert Kesselring's continuing air offensive.

Battle of the Black Sea: Soviet icebreaker Ledokol No. 7 hits a mine laid by the Luftwaffe and sinks between Novorossiysk and Kerch. There are 25 dead and 11 survivors.

Partisans: The Italian and German security services in eastern Bosnia under the overall command of General der Artillerie Paul Bader begin Operation Trio. The operation targets all insurgents between Sarajevo and Drina. Bader gives the Italians military control over civil affairs in the areas of operation, a key Italian goal for expanding their zone of control in the Balkans despite their continuing difficulties with the partisans. The first phase of Operation Trio, an advance east toward the Drina, begins today, but this is a massive operation using regular army troops as well as auxiliaries that is intended to last for throughout the spring. Italian, German, Croatian, and Chetnik forces take part.

The 718th Infantry Division advances from Sarajevo, Olovo, and Tuzla. The initial goal is to relieve an embattled Croatian garrison at Rogatica in an area swarming with partisans in the surrounding countryside. The Axis forces advance without much difficulty, but the effort is hampered by intra-Axis hostilities between the royalist Chetniks and the Ustaše Black Legion led by Jure Francetić.

In Rennes, France, the French Resistance makes an unsuccessful attempt to assassinate French fascist Jacques Doriot. He is a founder of the Légion des Volontaires Français (LVF), a French unit of the Wehrmacht. Doriot has fought in the Soviet Union as part of Operation Barbarossa and is highly esteemed by the Germans. Separately, German security troops in Rouen shoot 30 hostages in reprisal for an attack on a German troop train.

German Military: At lunch with Hitler and other top generals, Reichsfuhrer SS Heinrich Himmler broaches the idea of using SS troops extensively on the Eastern Front in regular military formations. This has been done very sparingly so far, usually only in emergency situations, as the SS is considered more of a "special operations" force. General Franz Halder notes in his diary that he takes "sharp issue" with this idea, perhaps realizing that this would introduce an entirely separate military command outside of the normal Wehrmacht chain of command. This would reduce both Halder's own control of operations and introduce problems in coordinating attacks.

US Military: US Army Air Force Major General George H. Brett assumes command of all Allied Air Forces in Australia and nearby areas. This includes units in Port Moresby, New Guinea.

The Berlin Philharmonic puts on a concert for Hitler's birthday, 20 April 1942. He is not in attendance, as he remains at his Fuhrer Headquarters in East Prussia.
German Homefront: It is Adolf Hitler's birthday, always marked during the Third Reich with celebrations and speeches. Today's celebration is relatively low-key, and Hitler's main event is having lunch at Fuhrer Headquarters in Rastenburg with his top generals such as Halder and Himmler. New French leader (under figurehead Petain) Pierre Laval lavishes praise on Hitler ("He is a conqueror who did not abuse his victory") and characterizes the war as an attack on "Bolshevism."

Holocaust: Fritz Sauckel, the Reich Plenipotentiary General for Labor Mobilization, sends a memo to Alfred Rosenberg, Reich Minister for the Occupied Eastern Territories, about forced labor. It details a program of abduction and enslavement, focused mainly on Rosenberg's sphere of authority in Eastern Europe. Approximately 5 million men and women will be forced to work for the Reich as slave labor under this program. The document states that the program is necessary "for the armament of the Armed Forces and also for the nutrition of the Homeland" and " to the profit of Germany and her allies."

American Homefront: The San Francisco News reports that "The Army today ordered two more Los Angeles areas cleared of 2000 Japanese by noon of April 29." General De Witt also announces that the army is building a new "reception center" for internees at Tula Lake. All internees are urged to deposit large sums of money and valuables for safekeeping before going to the camps, as there will be no banks or other repositories there. The Army also announces that evacuations will "proceed at a rapid rate from now on."
