Take Ichi convoy
The Take-Ichi sendan (Japanese: 竹一船団; lit. 'Bamboo Number One convoy') was a Japanese naval convoy of World War II. The convoy left occupied Shanghai on 17 April 1944, carrying two infantry divisions to reinforce Japan's defensive positions in the Philippines and western New Guinea. United States Navy (USN) submarines attacked the convoy on 26 April and 6 May, sinking four transports and killing more than 4,000 soldiers.
