US NAVY

PACIFIC—Yacht Isabel (PY‑10) is sighted by floatplane from Japanese seaplane carrier Kamikawa Maru at about 13°24'N,112°21'E. Later in the day, Isabel receives orders to return to Manila.

US NAVY

PACIFIC—Japan assures the U.S. that her troop movements in French Indochina are only precautionary.

            Carrier Lexington (CV‑2) in TF 12 (Rear Admiral John H. Newton) sails for Midway to ferry USMC SB2Us (VMSB231) to that atoll. Like Enterprise (CV‑6)'s deployment to Wake, Lexington's to Midway is in response to the "War Warning" of 27 November.

ATLANTIC—TU 4.1.3 (Commander George W. Johnson) assumes escort duty for convoy HX 163 in North Atlantic.

            Destroyer Babbitt (DD‑128), in TU 4.1.5 escorting convoy ON 41, depth‑charges suspected submarine contact without result.

PACIFIC—River gunboats Luzon (PR‑7) and Oahu (PR‑6) (Rear Admiral William A. Glassford, Commander Yangtze Patrol, in Luzon), followed later by submarine rescue vessel Pigeon (ASR‑6) and minesweeper Finch (AM‑9), reach Manila.

            River gunboat Mindanao (PR‑8) (Captain Lester J. Hudson, Commander South China Patrol, embarked) sails from Hong Kong, British Crown Colony, for Manila. She is the last U.S. Navy ship to depart Chinese waters prior to war. Luzon Stevedoring Company tug Ranger follows subsequently, carrying spare parts and 800 3‑inch shells for Mindanao’s main battery (previously stored ashore at Hong Kong). Only two U.S. naval vessels remain in Chinese waters: river gunboat Wake (ex‑Guam) (PR‑3) at Shanghai to maintain communications until a radio station is established at the Consulate General with Navy equipment, and river gunboat Tutuila (PR‑4) at Chungking, where she furnishes essential services to the U.S. Embassy. Wake had received her new name on 23 January 1941 to clear the name Guam for a new large cruiser (CB 2).

            Carrier Enterprise (CV‑6) ferries USMC F4Fs (VMF 211) to Wake Island; TF 8 (Vice Admiral William F. Halsey, Jr.) then shapes a course to return to Pearl Harbor. TF 8 is slated to reach Pearl on 6 December. Heavy weather on 5‑6December, however, will result in a delay in fueling the force's destroyers and push back the time of arrival in Pearl from the afternoon of the 6th to the morning of the 7th. That same day, a routine scouting flight from the carrier sights Honolulu‑bound tug Sonoma (AT‑12) with Pan American Airways barges PAB No. 2 and PAB No. 4 in tow. Sonoma, armed with only two .30‑caliber machine guns, will eventually reach Honolulu on 15 December 1941, with her tows.

            Japanese naval land attack plane (Chitose Kokutai) reconnoiters Wake Island undetected.

ATLANTIC—TU 4.1.5 (Commander William K. Phillips) reaches MOMP to escort convoy ON 41 which has been delayed by bad weather.

            TU 4.1.6 (Commander Gilbert C. Hoover), encounters "mountainous" seas as it continues to escort convoy HX 161; destroyer Roe (DD‑418) suffers two sailors hurt when torpedo breaks loose atop her after deckhouse.

US NAVY

ATLANTIC—Unarmed U.S. freighter Sagadahoc is torpedoed and sunk by German submarine U‑124 in South Atlantic, 21°50'S,07°50'W. One man of the 37‑man crew is lost.

            Destroyer Mayo (DD‑422), in TU 4.1.5 en route to MOMP and convoy ON 41, encounters two British ships, HMS Tenacity and merchantman Meademere, burning navigation lights south of Iceland; when they fail to answer challenge, Mayo illuminates them with star shells, at which point they turn off lights and answer challenge promptly.

PACIFIC—Yacht Isabel (PY‑10) sails for coast of French Indochina, deployed in accordance with President Roosevelt's "defensive information patrol" order.

            Submarine Argonaut (SS‑166) arrives off Midway Island on simulated war patrol.

Tuesday, 2 December 1941

US NAVY

UNITED STATES—U.S. freighter Dunboyne receives first naval Armed Guard crew. By the end of World War II, the U.S. Navy will arm some 6,236 merchantmen; approximately 144,970 officers and enlisted men will defend these merchant vessels in every theater of war.

ATLANTIC—German submarine U‑43 again attacks unarmed U.S. tanker Astral and this time torpedoes and sinks her at 35°40'N,24°00'W. There are no survivors from the 37‑man merchant crew. 

            Weather encountered by convoy ONS 39, being escorted by TU 4.1.4 (Captain Alan G. Kirk) worsens to the extent that the watch on board destroyer Plunkett (DD‑431) cannot be relieved because officers and men cannot safely traverse the weather decks.

            TU 4.1.5 (Commander William K. Phillips) clears Reykjavik, Iceland, to rendezvous with convoy ON 41, which due to poor weather will be 48 hours late to the MOMP. Over the ensuing period at sea, TU 4.1.5 battles "consistently severe" weather conditions that will cause varying degrees of damage to all of the ships in the task unit. Although ships of the unit carry out attacks (see 5, 9 and 11 December), there will be no U‑boat attacks on the merchantmen under their protection.

            TU 4.1.6 (Commander Gilbert C. Hoover), escorting convoy HX 161, encounters heavy weather; destroyer Bernadou (DD‑153) suffers storm damage; destroyers Roe (DD‑418) and Lea (DD‑118) each lose a man overboard. Neithersailor is recovered (see 4 December).

PACIFIC—Submarine Trout (SS‑202) arrives off Midway Island on simulated war patrol.

Monday, 1 December 1941

US NAVY

ATLANTIC—Patrol Wing 9 (Lieutenant Commander Thomas U. Sisson) is established at Quonset Point, Rhode Island.  

            German submarine U‑575 encounters and tracks unarmed U.S. tanker Astral, the latter en route from Aruba, N.W.I., to Lisbon, Portugal, with a cargo of 78,200 barrels of gasoline and kerosene. After seeing that Astral is unarmed and bears prominent neutrality markings, however, the U‑boat's commanding officer, Kapitanleutnant Gunther Heydemann, allows the American ship to pass unmolested. Subsequently, another submarine in the vicinity, U‑43, encounters Astral and attacks her, but her torpedoes miss their mark (see 2 December).

            TU 4.1.2 (Commander Fred D. Kirtland), accompanied by salvage vessel Redwing (ARS‑4) and oiler Sapelo (AO‑11), while escorting convoy HX 162, encounters heavy weather that scatters 35 merchantmen. Destroyers Charles F. Hughes (DD‑428), Madison (DD‑425), Lansdale (DD‑426), Wilkes (DD‑441) and Sturtevant (DD‑240) all suffer storm damage of varying degrees (see 7 December).

            Destroyer Livermore (DD‑429), escorting convoy ONS 39, is dispatched to investigate darkened merchantman steaming on opposite course. Livermore trails her and after determining her to be Panamanian freighter Ramapo, enroute to join convoy SC 56, allows her to continue her voyage after being warned not to radio a report of contact with a convoy.

PACIFIC—President orders a "defensive information patrol" of "three small ships" established off the coast of French Indochina; he specifically designates yacht Isabel (PY‑10) (reserve flagship for Commander in Chief Asiatic Fleet) as one of the trio of vessels (see 3 and 6 December). Schooner Lanikai is acquired and commissioned, but the start of the war results in her planned mission being cancelled. The third vessel, schooner Molly Moore, is selected for the mission but is never taken over. Lanikai's civilian career had seen her used as a "prop" in the filming of motion picture “Hurricane" that starred Dorothy Lamour and Jon Hall.

            U.S. passenger liner President Harrison arrives at Olongapo, P.I., with the remaining elements of the 4th Marine Regiment (Colonel Samuel L. Howard, USMC) withdrawn from Shanghai. President Harrison soon sails to bring out the last marines from China (see 8 December).

            As river gunboats Luzon (PR‑7) and Oahu (PR‑6) (Rear Admiral William A. Glassford, Commander Yangtze Patrol, in Luzon), submarine rescue vessel Pigeon (ASR‑6) and minesweeper Finch (AM‑9) proceed toward Manila, they become the object of curiosity by Japanese forces in the vicinity; first a floatplane circles the formation, then seven Japanese warships of various types.

PACIFIC—Japanese Foreign Minister Tojo rejects U.S. proposals for settling Far East crisis.

            Small reconnaissance seaplane from Japanese submarine I 10 reconnoiters Suva Bay, Fiji.

            U.S. passenger liner President Madison arrives at Olongapo, P.I., and disembarks the 2d Battalion, 4th Marine Regiment (Lieutenant Colonel Donald Curtis, USMC). President Madison will then proceed on to Singapore. 

            River gunboats Luzon (PR‑7) and Oahu (PR‑6) (Rear Admiral William A. Glassford, Commander Yangtze Patrol, in Luzon) rendezvous with submarine rescue vessel Pigeon (ASR‑6) and minesweeper Finch (AM‑9); they will remain in company until 3 December.

ATLANTIC—Destroyer Decatur (DD‑341), in TU 4.1.4 (Captain Alan G. Kirk), escorting convoy ONS 39, carries out depth charge attack on suspicious contact, 59°24'N, 27°03'W.
