AUGUST 10, 1943




Viciously attacking a Japanese submarine by ramming, depth charges and gun fire, a U. S. Navy submarine chaser sank the underseas raider with all hands in the Pacific 15 minutes after lookouts detected her periscopes scan­ning the convoy which the 'chaser was protecting.

The attack, carried out by the USS PC‑487 under the command of Lieu­tenant W. Gordon Cornell, USNR., Port Richmond, Staten Island, N. Y., occurred recently as the 'chaser and other escort vessels guarded a convoy headed for a United States base.



N. D. COMMUNIQUÉ NO. 456, AUGUST 12, 1943

North Pacific.


1. On August 12, at about 8:11 A. M. east longitude time, a formation of nine Army Liberator (Consolidated B‑24) heavy bombers attacked Japanese installations in the Kurile Islands. Numerous hits were scored in the desig­nated target areas. About forty enemy fighters intercepted of which five were shot dawn and others probably destroyed or damaged. Two of the U. S. bombers are missing.





The President of the United States and the Prime Minister of Great Britain, after consultation with the British Admiralty, the United States Navy Department and the Canadian Department of National Defence for Naval Services, have issued the following monthly statement on the progress of the anti‑U‑Boat war:


During the month of July very poor results were obtained by the U‑Boats from their widespread effort against the shipping of the Allies. The steady flow of trans‑Atlantic supplies on the greatest scale has con­tinued unmolested, and such sinking as have taken place in distant areas have had but an insignificant effect on the conduct of the war by the Allies. In fact, July is probably our most successful month, because the imports have been high, shipping losses moderate and U‑boat sinkings heavy.

Before the descent upon Sicily an armada of warships, troop trans­ports, supply ships and landing craft proceeded through Atlantic and Mediterranean waters with scarcely any interference from U‑boats. Large reinforcements have also been landed in that Island. Over 2,500 vessels were involved in these operations and the losses are only about 80,000 tons. On the other hand the U‑boats which attempted to interfere with these operations suffered severe losses.

Our offensive operations against Axis submarines continue to progress most favourably in all areas, and during May, June and July we have sunk at sea a total of over 90 U‑boats, which represents an average loss of nearly one U‑boat a day over the period.

The decline in the effectiveness of the U‑boats is illustrated by the following figures:




In the first six months of 1943, the number of ships sunk per U‑boat operating was only half that in the last six months of 1942 and only a quarter that in the first half of 1942.

The tonnage of shipping in the service of the United Nations continues to show a considerable net increase. During 1943 new ships completed by the Allies exceed all sinkings from all causes by upwards of three million tons.

In spite of this very favourable progress in the battle against the U‑boat, it must be remembered that the enemy still has large U‑boat re­serves, completed and under construction. It is necessary, therefore, to prepare for intensification of the battle both at sea and in the shipyards and to use our shipping with utmost economy to strengthen and speed the general offensive of the United Nations. But we can expect continued success only if we do not relax our efforts in any way.






N. D. COMMUNIQUÉ NO. 457, AUGUST 14, 1943

Pacific and Far East.

N. D. COMMUNIQUÉ NO. 458, AUGUST 15, 1943


1. The U. S. Submarine Pickerel has failed to return from patrol opera­tions and must be presumed to be lost. The next of kin of personnel in the Pickerel have been so informed.




2. The following U. S. Naval vessels have been lost in action against the enemy in operations in this area:


(a) USS PG 496 (Submarine Chaser) sunk 4 June, 1943, as result of underwater explosion.




(b) USS Redwing (Submarine Rescue. Vessel) sunk 29 June, 1943, as result of underwater explosion.

(c) USS Sentinel (Mine Sweeper) sunk 11 July, 1943, in landing operation off Sicily.

(d) USS Maddox (Destroyer) sunk 10 July, 1943, by aircraft off Sicily.




3. The USS Plymouth (Gunboat) was sunk a short distance off the North Carolina coast on 5 August, 1943, as result of underwater explosion.

4. The next of kin of all casualties aboard the above named vessels have been notified.



N. D. COMMUNIQUÉ NO. 459, AUGUST 21, 1943

North Pacific.


1. A Task Force of the Pacific Fleet has landed a force of United States and Canadian troops on Kiska, beginning on August 15th.

2. No Japanese have been found. There were indications of recent hasty evacuation of the Japanese garrison. Presumably, the heavy bombardments by our ships and planes that have been carried on for some time and the danger to their supply lines by our capture of Attu made the enemy positions on Kiska untenable. It is not known how the Japanese got away, but it is possible that enemy surface ships were able to reach Kiska under cover of the heavy fogs that have been prevalent.

3. Since the air and surface bombardments in the latter part of July had apparently destroyed Japanese radio equipment on Kiska, the assumption was that they were not in communication with the homeland. Consequently, no release of Allied operations against Kiska has been made since July 31, as it would have conveyed information to the enemy which he otherwise would not have had. This particularly applied to the period during which the trans­ports were in areas exposed to enemy submarine attacks and while they were unloading.

October 3:


Announcement is made that U. S. forces have occupied positions in the Andreanof group of the Aleutian Islands, without opposition. (Communiqué No. 138). Adak is the island occupied (Communiqué No. 370), and the estab­lishment of adequate airfields enables U. S. heavy bombers and fighters to operate from there in almost daily missions against the Japanese positions in the Western Aleutians. Throughout October, U. S. planes bomb and strafe the enemy ashore, and attack his shipping supply lines. (Communiqués Nos. 140‑143‑145‑150‑155‑157‑160‑161‑162‑170) Date of Adak occupation was August 30.

U. S. forces occupy Amchitka Island, only 63 nautical miles from Kiska, without opposition from the enemy. (Occupation of Amchitka announced in Communiqué No. 370, on May 7, 1943.) Following the occupation, an airfield is established on Amchitka with enemy opposition consisting of a few in­effectual raids by small numbers of planes (Communiqués Nos. 268‑273‑281­287). Date of Amchitka occupation was January 12.




With completion of a close‑up base on Amchitka, U. S. planes execute nine attacks on Kiska during the month, dropping more than 1,000 bombs, No U. S. planes are lost in these operations. (Communiqué No. 298) .




Intensification of the campaign against the Japanese in the Western Aleutians Increases. On March 15, U. S. Army heavy and medium bombers, escorted by fighters, carry out six missions against Kiska in the largest-scale attack thus far. (Communiqué No. 314). Raids on the enemy average better than one a day during the month.

On March 26, U. S. light forces patrolling to the westward of Attu Island engage a Japanese force composed of two heavy cruisers, two light cruisers, four destroyers and two cargo ships. Shell hits are scored on both of the Japanese heavy cruisers and one of the light cruisers. At least one torpedo hit is scored on an enemy heavy cruiser. U. S. vessels receive minor hits. (Communiqués Nos. 327‑365).




The month sees Kiska subjected to air attacks on a mass basis with occasional raids on Attu. The peak day is April 19, when 15 attacks are carried out against Kiska (Communiqué No. 351). Kiska twice is bombed 13 times in a day, on April 15 and April 25. (Communiqués Nos. 346 and 357). The month's average is slightly under five missions a day.






Air attacks on Kiska and Attu continue during the early days of the month, and then, on May 11, U. S. forces land on Attu. (Communiqué No. 376). Supported by bombardment of enemy positions by U. S. Naval surface forces, U. S. Army troops advance inland on Attu from the main landing points on the northeast and southeast ends of the island. In three weeks of fighting made difficult by Attu's rugged terrain and unfavorable weather, U. S. troops complete conquest of Attu. By June 1, all organized enemy resistance has ceased. (Communiqué No. 401).




U. S. forces, now in possession of key positions in the Western Aleutians, concentrate attention on Kiska, and carry out bombing and strafing missions whenever the weather will permit. (Communiqués Nos. 400‑402‑403‑407‑409-­414‑420‑423‑424‑425‑427) .




U. S. Naval surface forces Join in the assault on Kiska, bombarding enemy shore positions on July 6‑9‑11‑14‑15‑20‑22‑30. (Communiqués Nos. 436‑438­-439‑441‑442-446‑448‑455) .

Meanwhile, U. S. Army bombers and fighters continue heavy attacks on all enemy positions on the island.
