The naval war now entered upon a new phase. The shores of Great Britain had for many years been so thoroughly protected by the British navy that few coast fortifications had been built, except at important naval stations. Invasion on a grand scale was plainly impossible, so long as the British fleets held control of the sea. With German guns across the Channel almost within hearing it was evident that a raiding party might easily reach the English shore on some foggy night. The English people were much disturbed. They had read the accounts of the horrible brutalities of the German troops in Belgium and eastern France, and they imagined their feelings if a band of such ferocious brutes were to land in England and pillage their peaceful homes. There was a humorous side to the way in which the yeomanry and territorials entrenched themselves along the eastern coast line, but the Germans, angry at the failure of their fleets, determined to disturb the British peace by raids, slight as the military advantage of such raids might be. On November 2d a fleet of German warships sailed from the Elbe. They were three battle cruisers, the Seydlitz, the Moltke, and the Von Der Tann; two armored cruisers, the Blucher and the York, and three light cruisers, the Kolberg, the Graudenz, and the Strasburg. They were mainly fast vessels and the battle cruisers carried eleven-inch guns. Early in the morning they ran through the nets of a British fishing fleet. Later an old coast police boat, the Halcyon, was shot at a few times. About eight o'clock they were opposite Yarmouth, and proceeded to bombard that naval station from a distance of about ten miles. Their range was poor and their shells did no damage. They then turned swiftly for home, but on the road back the York struck a mine, and was sunk.

Early in the morning early risers in Scarborough saw in the north four strange ships. Scarborough was absolutely without defense. It had once been an artillery depot but in recent years had been a cavalry station, and some few troops of this service were quartered there. Otherwise it was an open seaside resort. The German ships poured shells into the defenseless town, aiming at every large object they could see, the Grand Hotel, the gas works, the water works and the wireless station. Churches, public buildings, and hospitals were hit, as well as private houses. Over five hundred shells were fired. Then the ships turned around and moved away. The streets were crowded with puzzled and scared inhabitants, many of whom, as is customary in watering places, were women, children and invalids.
