Thanks to CHUCK MYLES (1068-1989) for the huge task of compiling all this data. Every time a U-Boat took on fuel in any foreign port, on the high seas, from another U-Boat, from another ship - any way at all that a U-Boat took on fuel, CHUCK put it on this list. This is a very complete list.

U-704 took on fuel from U-461 about 29 July, 1942. She had departed her home port (the 7th U-BootFlotille at St. Nazaire) on 30 June. She joined GROUP WOLF in the North Atlantic and pursued an unidentified convoy with no results. Later, U-704 attacked CONVOY ON.113, took on fuel as indicated, then joined GROUP STEINBRINK, attacking CONVOY ON.115; then later attacked CONVOY SC.94 where U-704 suffered damage. She withdrew from the battlefield and arrived her home port on 16 August, 1942.
