27th Coast Artillery (United States)
military unit
The 27th Coast Artillery Battalion was a Coast Artillery battalion in the United States Army. It was the garrison of the Harbor Defenses of Bermuda, part of the US Army's Bermuda Base Command, from February 1942 through June 1944. A predecessor unit in World War I was the 27th Artillery (Coast Artillery Corps), which existed briefly from October through December 1918.
World War I
The 27th Artillery (Coast Artillery Corps), which was a regiment, was organized in October 1918 at Fort Stevens, Oregon. Moved to Camp Eustis, Virginia later that month; demobilized there in December 1918.
World War II
The 27th Coast Artillery Battalion (Composite) was organized on 20 February 1942 at Castle Harbour, Bermuda by redesignating US Army coast artillery units already in Bermuda. These included Battery F, 52nd Coast Artillery (CA) Regiment and Batteries B, G, and H (searchlight) of the 53rd Coast Artillery Regiment; the latter three had been redesignated from components of the 57th CA in July 1941. On 1 August 1943 the identifier "6-inch gun" was added to the battalion's designation, as the primary batteries (construction nos. 283 and 284) garrisoned by it at that time were of that caliber. The 27th CA Battalion was inactivated at the Royal Bermuda Yacht Club on 1 June 1944.

Why this record matters

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 26, 2026. The linked authority identifier is Q60786346. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1942, 1944, 1918 and 1941.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
