The first of our submarine voyagers in the Baltic was Lieutenant-Commander Max Horton, in E9. He distinguished himself in the early months of the war by sinking a German light cruiser and a destroyer in the North Sea. In January 1915 he entered the Baltic, sank a destroyer on the 29th, a transport on 11th May, and on 5th June another transport and another destroyer. On 2nd July he torpedoed the Pommern, a 13,000 ton battleship, with 11-inch guns. He was then joined by E1 (Commander N. F. Laurence), and on 22nd August by E8, whose log contains the best account of the long, intricate, and dangerous voyage out.

Commander Goodhart started in E8 on 18th August, with 1,500 miles of adventure between him and his new base at Reval. He passed warily up the Skagerrack, avoiding the central line of traffic, and diving once under a whole fleet of steam trawlers. At 7 p.m. he came to the surface again, rounded the Skaw at full speed, and entered the Kattegat. In the fading light several merchantmen were seen going north; the shore and island beacons began to twinkle one by one—Hamnskau, Vinga, Skaw, Trindelen, Anholt. But the night was short; by 3 a.m. he must dive again and lie on shoal ground while traffic passed above him. At 5.25 he ventured up, but was put down quickly by a steamer; to be seen might rouse a hunt. At 7 he came up again and did a survey of l-½ hours in a friendly mist, then down again, to crawl at 3 knots till 1 p.m., when he was off the entrance to the Sound.

Here he must choose between going forward submerged, or waiting for darkness and attempting the channel on the surface. He decided to continue his dive into the Sound and wait for night inside. He went in at 50 feet, came up to 21 feet to verify his position, down again to 50, and altered course to pass through the northern narrows. At 4.10 p.m. he was east of Helsingor Light; at 5.20, after another observation, he went to bottom in 11 fathoms, to wait for darkness. At 8.15 p.m. he rose to the surface; the Danish shore was bright with many lights, the Swedish shore all dark. He steered south-westward on the surface, altering course to avoid being seen by two destroyers which were going north along the Danish shore at a great pace; but now one of them suddenly turned south and stopped. E8 ran on, but into still more dangerous waters. The lights of Copenhagen were bright, and a searchlight was working from Middle Ground Fort; now and again it swept across the submarine. Then came several fishing boats, then two red lights moving south, close over to the Danish shore. There was nothing to show that E8 had been seen, and she headed boldly for Flint Channel.

Off Malmo the shorelights were dazzling, and it was extremely hard to fix a position. There were also many fishing boats about, each carrying two bright lights. Commander Goodhart ordered the boat to be trimmed down, with upper deck awash, and proceeded with one engine only, at 7 knots. He steadied his course through Flint Channel, passing at least twenty vessels with white lights, and one making searchlight signals in the air. No sooner had these been avoided by changing course than a tramp came along, showing first a green light and then three white ones. She seemed to have anchored; but now two other vessels had to be dodged, and then the ship with the searchlight. Immediately afterwards, when just north-east of the lightship's three vertical red lights, E8 was viewed at last; a small torpedo boat sighted her as she was creeping by within 200 yards.

The hunt was up; the enemy showed red and green flares, and altered course to chase. E8 dived, and struck "very strong bottom" at 19 feet, and immediately afterwards at 14 feet. A succession of bumps brought her to a stop. It was 11.40 p.m. After an anxious quarter of an hour Commander Goodhart decided to rise to the surface. On his starboard quarter was the Drogden lightship, ahead of him a large destroyer or small cruiser—the ship which had been signalling with searchlight. She was only 200 yards away, but the commander trimmed his boat deep, and stole past. This took four minutes, and he then found another destroyer right ahead, and within 100 yards. He could but dive; the boat struck bottom at 16 feet heavily, carrying away all blades of the starboard propeller. The pursuers could be heard overhead.

Life was now a matter of minutes and feet. The boat was still moving; at 12.15 a.m. she was at 18 feet, and bumping badly; at 12.19 the commander stopped her and came silently to the surface. The destroyer was still close on his starboard beam, and in one minute he had dived again as slowly as he dared; mercifully the water deepened as E8 glided away. She seemed to be escaping; but at 2.10 a.m. she struck bottom again, and when she ventured up after an hour, there again was the destroyer on her port beam. Happily this time she got down without being seen, and when she came up again at 7.15 there was nothing in sight.

But the danger was not over yet. E8 was nearly out of breath; her battery was running very low. After diving again to avoid a steamer and afterwards a destroyer, Commander Goodhart decided to find a good depth, and lie at the bottom till darkness gave him a chance of recharging. For eight long hours E8 lay like a stone in 23 fathoms. When she came up three or four vessels were patrolling close by, and the moon was too bright. She tried again, but was again put down by a shadowy destroyer to the southward. At last, ten minutes before midnight, she found a bit of quiet sea where she could take breath.

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.
