HMS Dunraven was a Q-Ship of the Royal Navy during World War I. On 8 August 1917, 130 miles southwest of Ushant in the Bay of Biscay, disguised as the collier Boverton and commanded by Gordon Campbell, VC, Dunraven spotted UC-71, commanded by Oberleutnant zur See Reinhold Saltzwedel. Saltzwedel believed the disguised ship was a merchant vessel. The U-boat submerged and closed with Dunraven before surfacing astern at 11:43 am and opening fire at long range. Dunraven made smoke and sent off a panic party (a small number of men who "abandon ship" during an attack to continue the impersonation of a merchant).
