Footnote 2: Q ships, also known as mystery ships, were disguised as unarmed merchantmen to lure German U-boats close enough for an attack. Although they enjoyed success in the spring and summer of 1917, by this point the Germans had long become aware of their existence, and were taking necessary precautions. The last German submarine to be sunk by a Q ship went down in August 1917, and the Navy Department’s resistance to operating them in American waters was based on the recognition that mystery ships had lost their usefulness.
