Fight Submarines To-day.

New York Times 100 years ago today, July 21, 1912:
Atlantic Fleet Battleships Begin Manoeuvres Off Block Island.
Special to The New York Times.
    NEWPORT, R. I., July 21.— A week's manoeuvres in night attacks at sea under warlike conditions will begin to-morrow morning with the first and second divisions of the Atlantic fleet against the submarines and destroyers in the vicinity of Block Island.
    The war plans will include the mining of harbors against the submarines and destroyers, and an attempt of the battleships to force an entrance from sea into Narragansett Bay to supposedly capture it as a base against the submarines and destroyers. Two groups of the destroyers will be employed against the submarines and two groups of destroyers will be with the battleships.
    Rear Admiral Aaron Ward will command the squadron composed of the flagship Florida, with the dreadnoughts Delaware and Utah, and flagship Louisiana flying the flag of Rear Admiral Cameron McR. Winslow and battleship Kansas of the second division.
    When the squadron returns it will mark the last sea fight Admiral Ward will have taken part in, as he lowers his flag on Aug. 1 to become Supervisor of New York, and will later go to duty with the General Board for a year and then retire from active service.
