Coastal artillery was a critical requirement at the start of the war. Although Bermuda had been heavily fortified over the previous centuries, and hundreds of artillery pieces had been emplaced, most were hopelessly obsolete. Of the newer guns, only two batteries, each of two 6-inch guns, were in serviceable condition (at St. David's Battery and Warwick Camp, both manned by the Bermuda Militia Artillery). Consequently, among the first American units deployed to Bermuda were batteries of artillery at Cooper's Island, Fort Albert and Fort Victoria on St. George's Island, Fort Langton at Prospect Camp, Warwick Camp, Tudor Hill, and also Scaur Hill Fort on Somerset Island. Subunits included "B" Battery, 57th Regiment, United States Army Coast Artillery Corps, deployed to Ackermann's Hill at Warwick Camp in 1941 with two 155mm GPF artillery guns on wheeled carriages, which were placed on "Panama mounts" by October 1941. All US Army defenses outside the leased baselands were withdrawn from Bermuda on the end of hostilities.
