Another officer who contributed greatly to the efficiency of the American forces was Captain E. R. G. R. Evans, R.N., who was detailed by Admiral Jellicoe at my request to act as liaison officer with our destroyers. No more fortunate selection could have been made. Captain Evans had earned fame as second in command of the Scott Antarctic expedition; he had spent much time in the United States and knew our people well; indeed when war broke out he was lecturing in our country on his polar experiences. A few days before our division arrived Captain Evans had distinguished himself in one of the most brilliant naval actions of the war. He was commander of the destroyer-leader _Broke_--a "destroyer-leader" being a destroyer of unusually large size--and in this battle three British vessels of this type had fought six German destroyers. Captain Evans's ship sank one German destroyer and rammed another, passing clear over its stern and cutting it nearly in two. The whole of England was ringing with this exploit, and it was a decided tribute to our men that Admiral Jellicoe consented to detail the commander of the _Broke_. He was a man of great intelligence, great energy, and, what was almost equally to the point, he was extremely companionable; whether he was relating his experiences at the South Pole, or telling us of active life on a destroyer, or swapping yarns with our officers, or giving us the value of his practical experiences in the war, Captain Evans was always at home with our men--indeed, he seemed to be almost one of us.
