Holland was commissioned in October of 1900 thus becoming the first of the
unbroken line of commissioned submarines in the United States Navy.
on the surface in Peconic Bay, she was the first submarine to use the
system of an air breathing engine and generator for surfaced propulsion
and a battery, electric motor combination for submerged propulsion.
This system is in use today in all but nuclear powered submarines.
Commanding Officer of Holland was Lt. Harry Caldwell who was Admiral
Dewey’s flag lieutenant during the Battle of Manila Bay.
