operation, but for the patience with which they bore the
almost continuous restriction to their ships, and the long
vigil without the opportunity of a contact with the enemy
forces. Just how well our ships succeeded in this essential
co-operation was expressed by Admiral Sir David Beatty
in the farewell speech which he made to them upon the day
of their departure for home. He said in part:
"I want, first of all, to thank you, Admiral Rodman, the captains, officers, and ships' companies of the magnificent squadron, for the wonderful co-operation and the loyalty you have given to me and to my admirals; and the assistance that you have given us in every duty you had to undertake.

But these were not the only large battleships which the United States had sent to European waters. Despite all the precautions which I have described, there was still one danger which constantly confronted American troop transports. By June and July, 1918, our troops were crossing the Atlantic in enormous numbers, about 300,000 a month, and were accomplishing most decisive results upon the battlefield. A successful attack upon a convoy, involving the sinking of one or more transports, would have had no important effect upon the war, but it would probably have improved German moral and possibly have injured that of the Americans. There was practically only one way in which such an attack could be made; one or more German battle-cruisers might slip out to sea and assail one of our troop convoys. In order to prepare for such a possibility, the Department sent three of our most powerful dreadnoughts to Berehaven, Ireland—the Nevada, Captain
