Battery Dyer Plan

World War I

The U.S. entry into World War I resulted in a widespread removal of large caliber coastal defense gun tubes for service in Europe. Many of the gun and mortar tubes removed were sent to arsenals for modification and mounting on mobile carriages, both wheeled and railroad. Most of the removed gun tubes never made it to Europe and were either remounted or remained at the arsenals until needed elsewhere. The guns of Battery Dyer were ordered dismounted for use abroad on 24 Aug 1917 and were transferred to Watervliet on 27 Nov 1917. The gun tubes eventually made their way to France and they were returned to the U.S. after the war. Battery Dyer was not rearmed. The carriages were ordered scrapped 26 May 1920.

A concrete BC and C.R.F. station was built on top of Battery Dyer in 1921 and transferred for service 6 Dec 1921 at a cost of $ 3,043.98.
