What really isn't clear is what happened to Lattin next. It is not known if he ever returned to his company after his wounding. He did however complete his three year term of service. He would be discharged on October 10, 1864.
During the later part of his life he did spend time at the Fitch Home for Disabled Soldiers in Darien, Connecticut. When he died on December 13, 1904, he would be buried in the section of Spring Grove Cemetery in Darien, where other residents of the Soldier's Home were buried.
