The soldiers' lot is located in Ayer, Massachusetts, in Section 1, lots 193, 203, 206, and 211, of Woodlawn Cemetery. The federal government purchased the lots from Woodlawn Cemetery in 1918. Most of the 52 men interred in the soldiers' lot died at Fort Devens, which is located nearby. The last interment was made in 1931. All of the interments in the soldiers' lot are known. Camp Devens was established in 1917 as part of the World War I mobilization effort. It was named after Major General Charles Devens, a Civil War veteran and Attorney General in the administration of Rutherford B. Hayes. Over the course of World War I, more than 100,000 troops came through the gates of Camp Devens. In 1931, the installation was renamed Fort Devens, and it continued to serve as a post for active duty soldiers until 1996, when it transitioned into an Army Reserve training center.
