On 22 March 1917, he enlisted with the army, and was a private in the Coast Artillery Corps (CAC), stationed at Fort Constitution in New Castle. The following year, the government began sending companies of CAC over to Europe. Lawrence departed New York on 17 Sept 1918, but was only overseas a few months, as he left Saint Nazarre, France on the USS Antigone on 21 Dec 1918. The US Army Transport Service Records listed him as being a private in Battery B, 52nd Artillery (CAC). His obit said he was a corporal, so his promotion must have been received following his return to the States. He was discharged from the army on 24 Jan 1919. When the Emerson Hovey VFW Post was organized in Portsmouth that year, Lawrence was a charter (and life) member.
