World War I (1917-1918)

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 Farnsworth were ordered dismounted for use abroad on 24 Aug 1917. They were transferred to NYC on 1 Oct 1917. The carriages were ordered scrapped in May 1918. Battery Farnsworth was not rearmed.

World War II (1941-1945)
