Vice Admiral William S. Sims, Commander, United States Naval Forces Operating in European Waters, to Office of Chief of Naval Operations
Cablegram Sent August 15, 1917
To Opnav Washington Serial No. 256
Two hundred and sixty eight.
Replying Opnav 13314 It is considered imperative that only regularly commissioned and experienced officers be sent for duty with destroyers stop The highly specialized installations of this type of vessel combined with the nature of their present service makes it dangerous to employ any but regularly trained officers.
