But only for two hours; daylight comes early in northern waters. At 2 a.m. Commander Goodhart dived again, and lay long in 17 fathoms, spending his time in studying the chart. He was now well out of the Sound, and clear of the Swedish coast. Right ahead was the island of Bornholm, and if that could be passed successfully, the Baltic lay open beyond, a long voyage still, but a less crowded thoroughfare. At 9 a.m. he came to the surface for three hours. By noon he was not far west of Ronne, and as he wished to make sure of getting past Bornholm unobserved, he decided to remain on the bottom till dark, then slip by and recharge his batteries for a long run north by daylight. By 7 p.m. he was on his way; by sunrise on the 21st he was passing the east coast of the great island of Gotland. At 9.2 p.m. he dived for a light cruiser, which passed over him; at 10 he returned to the surface and ran past the entrance to the Gulf of Riga and the island of Oesel. By 1 a.m. on August 22nd he had to dive for daylight, but at 3 he came up again, and ran ahead at full speed. At 8.30 a.m. on August 23rd he sighted Dagerort ahead, and joined Commander Max Horton in E9, passed with her and a Russian destroyer into the Gulf of Finland, and by 9 p.m. secured E8 in Reval harbour. Within twenty-four hours he had docked and overhauled her, replaced her broken propeller, and reported her ready for sea. Of the warships sunk by E8 and her consorts, and of their blockade of the German traffic in the Baltic, there is no need to speak. Their feats of war, brilliant as they were, formed only a minor part of the glory of their intricate and perilous voyages in a hostile sea. *CHAPTER XXVIII.* *THE MERCANTILE MARINE AND FISHING FLEETS.* Among the great deeds of the war there is one which, though hardly to be described in detail, ranks in truth among the greatest of all. It is a collective deed: the conduct of the whole British Mercantile Marine and the Fishing Fleet—Services not less worthy than the professional Navy and Army to represent the "decent and dauntless people" of these islands. It had been prophesied before the war that after three ships had been sunk by enemy submarines no merchantman would put to sea. The prophet, though himself a naval man, can have known little of the resourcefulness of his own Service, and still less of the temper of his fellow-countrymen.
