In the Great War

When the U.S. declared war on Germany in April 1917, a massive military buildup commenced, including the construction of a large fleet of small boats, the 110' United States Submarine Chasers. The mission of the subchasers was to find and attack U-boats, to hunt the enemy down.

This episode introduces the new chaser fleet, as the subchaser crews trained in the new science of antisubmarine warfare, and coped with the coldest New London winter in history.
