Part of the Harbor Defense of Puget Sound. Battery Valleau was designed to protect the Straight of Juan De Fuca and the Admiralty Inlet to Puget Sound.

Originally built with four, 6" M1905 rifles mounted on M1903 disappearing carriages in two separate batteries connected at an angle to one another. Each of these batteries is a two-story battery with two guns located on the upper level and the magazines and service rooms on the lower level. On the lower level of each battery, a common shell room and a common powder room serve both gun positions. Electrical power was provided from either the plant at Battery Moore, the central power plant, or commercial power. No shell or powder hoists were provided.

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 four 6" guns at Battery Valleau were listed for service overseas on 27 Aug 1917 and by 18 Jul 1918, they had been transferred. The guns were actually transferred on 31 Dec 1917 to Watervliet Arsenal, three of them were actually shipped to France (#18, #21, #22). These three guns were all returned to the U.S. after the end of the war and all three were reused in World War II batteries. The fourth gun, #22, did not make it overseas and was not reused in World War II.

Battery Valleau was not rearmed after the end of World War I and the carriages were all scrapped on 26 May 1920.

Current Status

The battery was clean and dry when visited. No guns or carriages were in place.
