I was skimming through a book about WWII Subs and decided to look up the one docked at Pearl Harbor, the USS Bowfin. During a War patrol the sub followed a 3 ship convoy into a harbor and engaged it. The Bowfin’s first Torpedo salvo missed and ended up hitting a Pier. When the Pier blew up it took a Crane and School Bus with it. Consequently the USS Bowfin is the only US Submarine with a Crane and Bus on its Battle Flag. The Captain reported back to Pearl Harbor and said “Sighted Bus, Sunk Same”. For some reason I find this so funny.
