            Halsey-Doolittle Raid: TF 16 (Vice Admiral William F. Halsey Jr.), formed around carriers Enterprise (CV-6) and Hornet (CV-8), approaches to within 650 miles of Japan. Discovery by Japanese guard boat No.23 Nitto Maru compels Vice Admiral Halsey to order Hornet to launch 16 USAAF B-25s (Lieutenant Colonel James H. Doolittle) earlier than planned. B-25s bomb targets in Tokyo, Yokosuka, Yokohama, Kobe, and Nagoya; one B-25 bombs and damages carrier Ryuho (being converted from submarine depot ship Taigei) at Yokosuka. Of the 16 B-25s launched, 15 are lost in occupied China, where brutal reprisals by Japanese against Chinese populace (Chekiang province) ensue; one B-25lands intact at Vladivostok where it and its crew are interned by the Soviets. SBDs (VB 3, VB 6) and F4Fs (VF 6) from Enterprise, meanwhile, attack Japanese guard boats ("picket" boats) encountered near TF 16, damaging armed merchant cruiser Awata Maru and guard boats Chokyu Maru, No.1 Iwate Maru, No.2 Asami Maru, Kaijin Maru, No.3Chinyo Maru, Eikichi Maru, Kowa Maru, and No.26 Nanshin Maru. Guard boats No.23 Nitto Maru and Nagato Maru, also damaged by SBDs and F4Fs from Enterprise, are sunk by gunfire of light cruiser Nashville (CL-43) (see 19April). While the material damage inflicted by the bombers is small, the psychological effect of an air raid on the Japanese capital itself is great. Most importantly, the Halsey-Doolittle Raid ends all debate within the Japanese high command whether or not a thrust against the important U.S. advanced naval base at Midway should be attempted.

Doolittle, take off from USS Hornet, standing with naval TF under Admiral Halsey some 800 miles from Tokyo, in morning and at 1215 begin strikes on Japanese homeland, hitting Tokyo, Kobe, Yokohama, and Nagoya with good effect. Search and fighter support are provided by planes of USS Enterprise. After the attack, all bombers head for China where they were to have come under control of General Stilwell, but because of poor weather conditions and the late hour, all crash-land or are abandoned by crews. One lands near Vladivostok and its crew is interned; 2 land in enemy territory and their crews are imprisoned, some of the flyers being executed on 15 October 1942. Admiral Halsey’s naval TF (the 2 carriers plus 4 cruisers, 8 DD’s, and 2 oilers) withdraw safely. This is the first occasion on which medium land bombers are moved by carriers and launched off enemy shores.
