Commander Goodhart rises to the surface at 9.0 A.M., but dives again at noon. We are now not far west of Rönne; and as he wishes to make sure of passing Bornholm unobserved, he decides to remain on the bottom till dark, then slip by and recharge his batteries, for a long run north by daylight. By 7.0 P.M. we are on our way, and eight hours later we are passing the east coast of the great island of Gotland. At 9.2 P.M. we dive for a light cruiser, which passes overhead forward; at 10.0 we return to the surface and proceed north-east, running past the entrance to the Gulf of Riga and the island of Oesel. By 1.0 A.M. on August 22, we have to dive for daylight; but by 3.0 we are up again, and going on our course full speed. At 8.30 A.M. we sight Dagerört ahead and join E. 9 (Commander Max Horton). In company with her and with a Russian destroyer, we pass into the entrance of the Gulf of Finland; and by 9.0 P.M., E. 8 is secured in Reval harbour. Within twenty-four hours, Commander Goodhart has docked and overhauled her, replaced her broken propeller, and reported her ready for sea. The career of E. 8 in the Baltic was long and successful. It began, so far as sinkings are concerned, with the destruction of the steamer _Margarette_ of Königsberg by gunfire, on October 5, 1915, and the most exciting day in the record was October 23, when the _Prinz Adalbert_, a cruiser of nearly 9,000 tons, fell to her first shot. E. 8 was cruising off Libau when, at 8.50 A.M., Commander Goodhart observed smoke on the horizon, and altered course to intercept the ship which was soon seen to be an enemy. She had three funnels and two very high masts, and was going west with two destroyers, zigzagging--one on each bow. Commander Goodhart ran on, at seven and a half knots, till he got within 3,000 yards, when he eased to five knots in order to lessen his wake. The wind was slight, from S.S.E., and there was bright sunlight. The conditions were ideal for an attack from the southward. All tubes were made ready; the enemy came on at an estimated speed of fifteen knots. At 9.28 the port destroyer passed ahead; four minutes later, Commander Goodhart fired his bow tube at the war-ship’s fore-bridge and began to look out for results.
