Searching "Dover Patrol - World War 1, I found reference to Bacon's "Dover Patrol" which came in a very detailed two volume version and a less detailed single volume version.
There is also "Dover Patrol" byJJ Bennett Navy/Channel/Zeebrugge in WW1

This book details the wildly adventurous career of Titanic officer Charles Herbert Lightoller. After surviving the Titanic disaster, Lightoller went on to command a torpedo boat in the Nore Defence Flotilla, and two destroyers of the Dover Patrol. A first-hand account, giving a vivid picture of how the "gentlemen of the other firm" felt towards the U-boats. Lightoller sank Werner Fürbringer's UB-110, and it is interesting to compare his account of their encounter with the one in Fips. The hardcover edition is a rarity, there is also a paperback edition, published by Bay Tree Press, which is more readily obtained. There is a hypertext at
