Source: January 31, 1916 War Diary Entry. Went missing per Circumstances of Death Card with Private Emerald Brittan Broadwell, reg. no. 53892.
“Previously reported missing, now for official purposes presumed to have died.
About 9 a.m. on January 30th, 1916, he and a comrade [Private Broadwell] left their trench under cover of fog. They reached an unoccupied enemy listening post and found some bombs which they broad back to their own lines. They then returned to the listening post intending to wait there and bomb the enemy when they attempted to reoccupy the post. Private Reeves nor his comrade ever returned and from that time nothing has been seen or heard of them.”
