710:. This was done with most mortar batteries; with four mortars in each pit the reloading time was excessive due to crowding of men and equipment. So, mortars were removed to leave two mortars per pit. The mortars were not shipped to France; most railway mortars remained in reserve through World War II. Some of Fort McKinley's 8-inch (203 mm) guns were dismounted for railway conversion, but never left the fort and were later remounted. The two 6-inch (152 mm) guns of Battery Carpenter and Fort Lyon's three six-inch guns were removed to be mounted on field carriages; all were shipped to France and later returned to the United States, with Battery Carpenter's guns returning to Fort McKinley. The Fort Lyon guns were eventually used elsewhere on new mountings in World War II. A history of the Coast Artillery in World War I states that none of the regiments in France equipped with 6-inch guns completed training in time to see action before the

In late 1941 Fort Lyon added three new temporary buildings, a wharf, and utilities to house 130 enlisted men and 6 officers. The three buildings included a 172-man mess hall, a 74-man enlisted barracks and a modified barracks to house 56 enlisted men and 6 officers. An
