squadron of the Grand Fleet. Scheer remarked that "A successful attack on such a convoy would not only result in the sinking of much tonnage, but would be a great military success, and would ... force the English to send more warships to the northern waters." Scheer instituted strict wireless silence in preparation for the planned attack. This denied the British the ability to intercept and decrypt German signals, which had previously been a significant advantage. The operation called for Hipper's battlecruisers to attack the convoy and its escorts on 23 April while the battleships of the High Seas Fleet stood by in support. At 05:00 on 23 April 1918, the High Seas Fleet left harbor with the intention of intercepting one of the heavily escorted convoys. Hipper's forces were west of Egerö, Norway, by 05:20 on 24 April. Despite the success in reaching the convoy route undetected, the operation failed due to faulty intelligence. Reports from U-boats indicated to Scheer that the convoys sailed at the start and middle of each week, but a west-bound convoy had left Bergen on Tuesday the 22nd and an east-bound group left Methil, Scotland, on the 24th, a Thursday. As a result, there was no convoy for Hipper to attack. The same day, one of screws slipped off, which caused serious damage to the power plant and allowed of water into the ship. was forced to break radio silence in order to inform Scheer of the ship's condition, which alerted the Royal Navy to the High Seas Fleet's activities. Beatty sortied with a force of 31 battleships and four battlecruisers, but was too late to intercept the retreating Germans. The Germans reached their defensive minefields early on 25 April, though approximately off Helgoland was torpedoed by the submarine , though she successfully returned to port. Fate was to have taken part in what would have amounted to the "death ride" of the High Seas Fleet shortly before the end of World War I. The bulk of the High Seas Fleet was to have sortied from their base in Wilhelmshaven to engage the British Grand Fleet; Scheer—by now the of the fleet—intended to inflict as much damage as possible on the British navy, in order to retain a better bargaining position for Germany, whatever the cost to the fleet. While the fleet was consolidating in Wilhelmshaven, war-weary sailors began deserting en masse. As and
