Operation Juno


Operation Juno was a German naval offensive late in the Norwegian Campaign. The German ships involved were the battleships and, the heavy cruiser and the destroyers,, and.
The mission was launched on 8 June 1940, as an attack on Harstad to relieve pressure on the German garrison at Narvik. After refuelling at Jan Mayen Island the mission became unnecessary as the Allies were evacuating from Norway. On his own initiative, however, the German commander, Admiral Marschall, decided to seek and destroy the Allied transports. The troop transport Orama, the tanker Oil Pioneer and the minesweepeing trawler were sunk. Marschall ordered the Admiral Hipper and the destroyers to Trondheim, where they arrived in the morning of 9 June.
The next day, Admiral Hipper attempted to leave Trondheim, but was forestalled by the sighting of a British submarine.

Sinking of HMS ''Glorious''

As a notorious sideline to Operation Juno, Scharnhorst under the command of Kapitän zur See Kurt-Caesar Hoffmann and Gneisenau sank the British aircraft carrier and her escorting destroyers and on 8 June at around 69° N off Norway.
On the night of 7–8 June, the Glorious, under the command of Captain Guy D'Oyly-Hughes, took on board 10 Gloster Gladiators and eight Hawker Hurricanes from No. 46 Squadron RAF and No. 263 Squadron Royal Air Force, the first landing of modern aircraft without arrestor hooks on a carrier. These had been flown off from land bases to keep them from being destroyed in the evacuation. Glorious was part of a troop convoy headed for Scapa Flow, also including the carrier.
In the early hours of 8 June, Glorious requested permission to proceed independently, and at a faster speed. According to Alan Beith, this was because D'Oyly-Hughes was impatient to hold courts-martial of his Commander, Flying, J. B. Heath, and Lieutenant Commander Evelyn Slessor. Heath had refused an order to attack certain shore targets on the grounds that his aircraft were unsuited to the task, and had therefore been left behind in Scapa to await trial.
It has been noted by Beith that Glorious was in a low state of readiness. The high crow's nest look-out position was not manned, leaving the observation task to the destroyers with much lower observation angles. Only 12 out of 18 of boilers were in use, so she could not develop full speed as fast as was required.
Most important, D'Oyly-Hughes failed to launch any aircraft to form a Combat Air Patrol around the carrier group, reportedly to give the aircrews a rest. The previous commander always had some aircraft in the air. Had he done so, Glorious might have been able to spot incoming threats, or have been able to either turn and run or fight. No aircraft were even on the deck for a quick launch. In her hangars were 10 Hurricanes and 10 Gladiators from the RAF, and her own nine Sea Gladiators plus five Swordfish.
While sailing through the Norwegian Sea, the carrier and her two escorts, the destroyers and, were intercepted by the German battleships and. The carrier and her escorts were sunk in two hours, roughly west of Harstad, with the loss of 1,519 men; there were only 45 survivors. The single survivor from Acasta was rescued by the Norwegian steam merchant Borgund which also saved 38 men from one of Glorious' lifeboats. All 39 men saved by Borgund were set ashore at Tórshavn in the Faroe Islands on 14 June.
Scharnhorsts salvoes hit Glorious at 16:32, before the latter's torpedo-bombers could be launched. Scharnhorsts second salvo, at 16:38, struck Glorious at the extreme range of, one of the longest range hits ever recorded.
A Gneisenau salvo subsequently hit the bridge. The destroyers had started to lay smoke to protect Glorious and themselves. Ardent and Acasta made continual attempts to launch torpedoes at the German ships. At about 17:39, Scharnhorst was hit by one of four torpedoes launched by Acasta. Fifty sailors were killed, of water flooded into her and her aft turret was put out of action.
Ardent was sunk at around 17:20 having made seven attacks with torpedoes. The approximate sinking position based on last transmission from Glorious:.
Admiral Wilhelm Marschall, aboard his flagship Gneisenau, ordered Scharnhorst to cease fire and wasting ammunition on Glorious. At this point, Gneisenau was closer to Glorious than Scharnhorst.

Aftermath

Scharnhorst in company with Gneisenau made for Trondheim for repairs. Due to their exposed position they were not able to stop to rescue survivors of any of the ships. On 13 June, 15 Fleet Air Arm Blackburn Skua bombers from Ark Royal attacked Scharnhorst in harbour, and, with only a single bomb struck her. 8 Blackburn Skua were lost in the process. The Blackburn Skua were withdrawn from the front lines in 1941, and retired in 1945.
As a result of the action, 1,519 servicemen on board the HMS Glorious, and were killed, exceeding any of the other great British naval disasters of the war, along the three warships, two RAF fighter squadrons were lost.
Despite this notable success, damage from the torpedo attacks forced Scharnhorst to return to Trondheim for emergency repairs. It was not until 23 June that she was able to reach Kiel and a dry dock. She remained there under repair for most of the rest of 1940. Although the sacrifice of Glorious was a great loss, the withdrawal of these two powerful German warships allowed the remaining Allied convoys to reach Britain with a greatly reduced threat.
