The largest single group of naval activities wherein cooperation is effected with the British is that in Ireland, all of them being under the jurisdiction of the commander in chief, coast of Ireland, who has been and is Admiral Sir Lewis Bayly, whose cordial appreciation of the work of our forces has gone far to stimulate the personnel coming under his direction. The chief of staff, destroyer flotillas, and the officer in charge of aviation in Ireland are designated by the British Admiralty as members of the staff of Admiral Bayly. [Sidenote: Battleship Division Six.] _Battleship Division Six_, Rear Admiral T.S. Rodgers, is based on Berehaven, Ireland, in readiness for the protection of convoys in general and of troop convoys in particular. Arrangements are in effect for the supply of their needs as to fuel and stores. While lack of destroyers has operated to restrict their training underway, they are in good material condition and their efficiency is being maintained by utilizing all available facilities. [Sidenote: The submarine patrol.] _Submarine Detachment_, Lieutenant Commanders Friedell and Grady, is based on Berehaven, Ireland, and maintains a submarine patrol off the west and south coasts of Ireland. Their service is hard; they have had a great deal of work at sea and have cheerfully met every demand made on them. Despite their relative isolation, they have maintained themselves in readiness with the aid of the submarine tender _Bushnell_, whose limited facilities have been utilized to the utmost. Their performances and condition of material and personnel reflect great credit on all concerned. [Sidenote: Destroyers at Queenstown.] (_a_) _The destroyers based on Queenstown_, Capt. F.R.P. Pringle, are the original United States naval force in European waters--a distinction which is an ever-present spur to cheerful efficiency under any and all circumstances and produces results which must be a satisfaction to their superiors. [Sidenote: Changes in destroyer personnel.] (_b_) Despite the fact that the requirements of supplying personnel for new destroyers has resulted in large changes in the original experienced destroyer personnel, this has been accomplished in such a manner as to maintain the operating efficiency of the force at or near its original high standard. (_c_) Aside from unavoidable casualties, the force is in good operating condition. The systemization of supply and repairs developed and maintained by the destroyer tenders _Melville_ and _Dixie_ effect the readiness of destroyers for sea with commendable promptness and with a view to the comfort of destroyer personnel during their short stays in port.
