3 Monday
Navy Department General Order No. 143 creates three independent fleets, each commanded by an admiral. Admiral Husband E. Kimmel becomes Commander in Chief U.S. Pacific Fleet (and also Commander in Chief U.S. Fleet in the event that two or more fleets operate together); Patrol Force U.S. Fleet becomes U.S. Atlantic Fleet under command of Admiral Ernest J. King; and Admiral Thomas C. Hart continues as Commander in Chief U.S. Asiatic Fleet.
During routine exercises in Hawaiian Operating Area off Oahu, destroyers Dale (DD 353) and Hull (DD 350) contact what they believe is a submarine. With all U.S. boats accounted for, Commander Destroyers Battle Force orders Lamson (DD 367) to join Dale and Hull. The ships are to maintain contact and to take offensive action only if attacked. Mahan (DD 364) joins in search as well. With speculation that the only possible reason a submarine would be in those waters would be to obtain supplies or land agents, Lamson accordingly searches the shoreline east of Diamond Head (see 4 February).
4 Tuesday
Fleet Landing Exercise (FLEX) No. 7 begins in Culebra-Vieques, Puerto Rico, area, with all available ships of the Atlantic Fleet and elements of the First Marine Division and the U.S. Army’s First Division, to train “Army and Navy Forces in the amphibious operations incident to a Joint Overseas Expedition.” Unlike FLEX No. 6 in 1940, bona fide transports are available for, and participate in, the maneuvers.
Search for submarine off Oahu, begun the previous day, continues. After destroyers Dale (DD 353) and Hull (DD 350) return to Pearl Harbor, destroyers Flusser (DD 368) and Drayton (DD 366) join Lamson (DD 367) in the hunt. Ultimately, however, the search is called off.

24 Monday
Auxiliary Bear (AG 29) and Interior Department motorship North Star rendezvous off Adelaide Island to begin evacuation of U.S. Antarctic Service East Base. Heavy pack ice south of this area, however, prevents the ships from reaching their destination. The two vessels retire north to Dallman Bay. The time spent in the Mechior Archipelago, however, is not unfruitful, as North Star’s people conduct surveys, make soundings, and make a geological study of the island group, in addition to collecting further examples of flora and fauna. Bear, meanwhile, gets under way soon thereafter to attempt passage through the pack ice to reach East Base. She is unsuccessful. Amid growing concern as to whether or not a full or partial evacuation can take place since mid-March and the shortening of the polar days is approaching, North Star, running short of supplies and fuel, is sent to Punta Arenas, Chile, to replenish and return if required (see 22 March).
