and fire first. Admiral Hipper rained fire on Glowworm, scoring several hits. Glowworm attempted to flee, but when it became apparent she could not break away from the pursuing cruiser, she turned toward Admiral Hipper and fired a spread of torpedoes, all of which missed. The British destroyer scored one hit on Admiral Hippers starboard bow before a rudder malfunction set the ship on a collision course with the German cruiser. The collision with Glowworm tore off a section of Admiral Hippers armored belt on the starboard side, as well as the ship's starboard torpedo launcher. Minor flooding caused a four degree list to starboard, though the ship was able to continue with the mission. Glowworms boilers exploded shortly after the collision, causing her to sink quickly. Forty survivors were picked up by the German ship. Admiral Hipper then resumed course toward Trondheim. The British destroyer had survived long enough to send a wireless message to the Royal Navy headquarters, which allowed the battlecruiser time to move into position to engage Scharnhorst and Gneisenau, though the German battleships used their superior speed to break off contact. One of Admiral Hipper'''s Arado seaplanes had to make an emergency landing in Eide, Norway, on 8 April. After trying to purchase fuel from locals, the aircrew were detained and handed over to the police. The Royal Norwegian Navy Air Service captured the Arado, which was painted in Norwegian colors and used by the Norwegians until 18 April when it was evacuated to Britain. After arriving off Trondheim, Admiral Hipper successfully passed herself off as a British warship long enough to steam past the Norwegian coastal artillery batteries. The ship entered the harbor and docked shortly before 05:30 to debark the mountain troops. After the ground troops seized control of the coastal batteries, the ship left Trondheim, bound for Germany. She was escorted by Friedrich Eckoldt; she reached Wilhelmshaven on 12 April, and went into drydock. The dockyard workers discovered the ship had been damaged more severely by the collision with Glowworm than had previously been thought. Nevertheless, repairs were completed in the span of two weeks. Operation Juno Marschall organized a mission to seize Harstad in Northern Norway in early June 1940; Admiral Hipper, the battleships Scharnhorst and Gneisenau, and four destroyers were tasked with the operation. The ships departed from Kiel on 4 June. Three days later, Admiral Hipper and the four
