LONDON, July 7. "I am pleased to inform the lords commissioners of the Admiralty that the German high sea fleet was brought to action on the 31st of May, 1910, to the westward of Jutland Bank, off the coast of Denmark." In those words, Vice-Admiral Sir John B. Jellicoe, commander-in-chief of the home fleet, opens his report to the Admiralty on the battle over which there has been so much discussion. Continuing, Admiral Jellicoe says: "The ships of the grand fleet, in pursuance of the general policy of periodical sweeps through the North Sea, had left its base on the previous day, in accordance with instructions issued by me in the early afternoon of Wednesday, 31st May, the first and second battle cruiser squadrons and destroyers from the first, ninth, tenth, and thirteenth flotillas, supported by the fifth battle squadron, were, in accordance with my directions, scouting to the southward of the battle fleet, which was accompanied by the third battle cruiser squadron, the first and second cruiser squadrons, the fourth light cruiser squadron, and the fourth, eleventh, and twelfth flotillas. The Junction of the battle fleet with the scouting force after the enemy had been sighted was delayed, owing to the southerly course steered by our advanced forces during the first hour after commencing their action with the enemy battle cruisers. This, or  I course, was unavoidable, as had our battle cruisers not followed the enemy to the southward, the main fleets would never have been in contact.
