Excerpts from the autobiography of Captain C.Q. Wright indicate he was the "Officer in Charge" of the B3 at Cavite. His crew launched the two subs off the deck of the "Ajax". They then retrofitted the gasoline powered engines and motors in the Cavite Navy Yard shop readying the subs for a 48-hour shake down cruise. The first tour of duty began with sealed orders at 1900 hours, guarding Manilla Bay, in the event hostilities broke out with Japan. Orders were to sink any Japanese war vessel that came into sight, although none did.
