On 4 June, 1918, U.S. submarine chasers arrived at Corfu, Greece, Base 25, in a small bay at Fustipidima Point, which they nicknamed American Bay. From Hunters of the Steel Sharks:

Ens. Dole and his fellow subchaser sailors arrived to discover a pristine bay in a picturesque setting of rocky terrain and ancient olive groves. “We have a location that is full of promise,” he writes home, describing the remote spot. “The place we are at had no name, so it has been named after this bunch.” Thus was coined the name American Bay, which was to be home to thirty-six chasers.
Soon the chasers at Corfu would be joining the barrage lines and hunting U-boats.
