USS S-33 (SS-138) - First, Second, and Third War Patrols

First, Second, and Third War Patrols

S-33 arrived at Dutch Harbor, Unalaska, in early July. On 7 July 1942, she departed on her first offensive war patrol. For the first week, she patrolled in the Adak area, then shifted to the Near Islands. There, off Agattu, fog prevailed from 15–29 July. On the morning of 30 July 1942, visibility increased to about four miles for a few hours but then diminished again. Six days later, the S-boat encountered her first clear day, but fog and mist soon returned. On 7 August 1942, S-33 was ordered back to Dutch Harbor.
