Commander Richard D. White's first sketch of a submarine attack.
This sketch appeared in a larger report that White sent to Rear Admiral Albert T. Gleaves, Commander of the U.S. Cruiser and Transport Force. White questioned the value of zigzagging, then the Navy's primary method of evading a submarine attack. White served at this time as commanding officer of the troop transport Orizaba.
