The fourth also contained a light cruiser squadron, a squadron of six gunboats for mine sweeping, and four flotillas of destroyers, each with a flotilla cruiser attached. The second fleet was composed of two battle squadrons, the first containing eight pre-dreadnaughts, and the second six. Attached to this fleet were also two cruiser squadrons, a mine layer squadron of seven vessels, four patrol flotillas, consisting of destroyers and torpedo boats, and seven flotillas of submarines. A third fleet contained two battle squadrons, mainly composed of old ships, with six cruiser squadrons. The English strength, outside home waters, consisted of the Mediterranean fleet, containing three battle cruisers, four armored cruisers, four ordinary cruisers and a flotilla of seventeen destroyers, together with submarines and torpedo boats. In eastern waters there were a battleship, two cruisers, and four sloops. In the China squadron there were one battleship, two armored cruisers, two ordinary cruisers, and a number of gunboats, destroyers, submarines, and torpedo boats. In New Zealand there were four cruisers. The Australian fleet contained a battle cruiser, three ordinary cruisers, three destroyers and two submarines. Other cruisers and gunboats were stationed at the Cape, the west coast of Africa, and along the western Atlantic. At the outbreak of the war two destroyers were purchased from Chile, and two Turkish battleships, building in England, were commandeered by the government. It is evident that the union of France and Britain made the Allies easily superior in the Mediterranean Sea, so that France was able to transport her African troops in safety, and the British commerce with India and the East could safely continue. The main field of the naval war, therefore, was the North Sea and the Baltic, where Germany had all her fleet, except a few naval raiders. The entrance to the Baltic was closed to the enemy by Denmark, which, as a neutral, was bound to prevent an enemy fleet from passing. Germany, however, by means of the Kiel Canal, could permit the largest battle fleet to pass from the Baltic to the North Sea. The German High Sea Fleet was weaker than the British home fleet by more than forty per cent, and the German policy, therefore, was to avoid a battle, until, through mine layers and submarines, the British power should have been sufficiently weakened. The form of the German coast made this plan easily possible. The various bays and river mouths provided safe retreat for the German ships, and the German fleet were made secure by the fortifications along the coast. On July the 29th, 1914, at the conclusion of the annual maneuvers, instead of being demobilized as would have been usual, the Grand Fleet of Great Britain sailed from Portland along the coast into the mists, and from that moment dominated the whole course of the war.
