USS Seahorse sailed on 20 October for her second war patrol. She sank three enemy trawlers in surface actions and then, along with the USS Trigger commenced a two day attack on a 17 ship Japanese convoy. Seahorse evaded three escort ships and fired three torpedos at two freighters. Four hours later she again attacked, sending three more torpedos at a tanker and another spread at a third freighter. Flames burst from each target as Japanese destroyers turned towards Seahorse but they were too late to catch her. Seahorse expended the last of her torpedos on 30 November. After manuevering for several hours she was finally able to fire her stern tubes at the enemy convoy. However, one torpedo exploded close aboard and the convoy opened fire on the vicinity of Seahorse. With so many explosions around her, it was impossible for her to determine whether any torpedos had hit. Low on fuel and out of torpedos, she returned to Pearl Harbor.

The logbook contains the signatures of five different Officers on board
The original USS Seahorse logbook also comes with
Maru Killer by Dave Bouslog
Slade Cutter Submarine Warrior by Carl LaVO
Both of the above books go into great deal concerning the second war
patrol of the USS Seahorse
and history really does come alive when you cross reference the logbook with the two books.
