HMS Apollo with refits and additions through to 1940.
As can be seen when comparing the two versions, the later Apollo had the twin funnels trunked together in 1937, in the same refit, the 5.5" guns were removed and the single 4" guns fitted in their place. In 1938 the 2pd weapons were greatly increased, the HACS units fitted to control the 4", the elevators enlarged to take the Sea Battle torpedo bombers. 1939 the first RADAR outfit was installed and more electronics were added to the ship as refits came due. This takes the ship through to April 1940.
The Norwegian Campaign:
HMS Apollo was added to Admiral Whitworths squadron containing HMS Majestic and HMS Warspite (BB's), HMS Hawkins, HMS Kent, HMS Surrey (CA's), with a dozen destroyers. Their brief was to intercept German shipping in the Trondheim and Narvik areas. The weather was appalling. The latest search radar on Majestic was a godsend. Not only did it manage to spot enemy forces it allowed the Admiral to 'see' were his own ships were and keep some cohesive control over their dispositions. Majestic 'saw' two large blips moving North at high speed, the 'chase' order was given but only Majestic and Apollo were able to match the speed of the enemy ships and even they started dropping behind. Admiral Whitworth called off the chase and the Scharnhorst and Gneisenau sailed off into the Atlantic unaware of how close to being caught they had been.
While recalling his ships together a distress call was heard from HMS Gloworm that had encountered the Hipper and its destroyer escorts. Kent, Surrey and four destroyers were sent to intercept the Hipper and search for survivors. The Hipper made it to Trondheim and secured the port and by the next morning had secured the airfield which was then used by the Germans for air support missions against the British ships. It was now that the Apollo came into its own. In a dawn raid, the Apollo's aircraft caught the Hipper in harbour, putting a torpedo into it and the Skuas hitting it twice with bombs. More Skuas and Griffons attacked the airfield and caught the Germans on the ground, destroying the aircraft and facilities with guns and bombs.
Kent, Surrey and the destroyers having missed the Hipper are ordered to sweep north through the Inner leads up to Narvik. Admiral Whitworth and the main body stay outside the Leeds and head north on a parallel course. The conditions have not improved much outside in the Norwegian Sea and the weather has kept a lot of the air superiority, gained by having the Apollo, is grounded aboard ship. The Inner Leads Squadron (ILS) runs into a group of four German destroyers which turn tail and dive back into Narvik fjord. Admiral Whitworth orders the ILS in after them. The line is led by HMS Hardy (Captain Warburton-Lee), Hereward, Surrey (Commodore Smith). Kent, Hero, Hotspur. (Anybody who has read the 'Smith' series by Alan Evans will recognise my Commodore).
Unknown to the ILS there is actually now ten destroyers stuck in Narvik due to lack of fuel. Conditions of low cloud and mist also hamper the squadrons activities. The squadron went down the fjord at 15-20 knots per the Commodores instructions. Passing one of the numerous cross fjords, the yell of torpedoes is heard from the lookouts, what looked like a veritable shoal of eight torpedoes burst out and onto the line of ships. Hardy and Hereward both received a torpedo hit each. Hardy, hit in the stern uses its momentum to run ashore, the crew flooding over the bow to the safety of dry land, then having to fight the German lookout position that had signalled when to fire the torpedoes to the hidden destroyer. That destroyer did not have much longer to live as in a brisk 5 minute action both Surrey and Kent hit the destroyer with multiple strikes that ignited magazines and literally blew it out of the water. The Hereward with its bows blown off managed to limp backwards out to where the bulk of the squadron waited. It would be many months before Hereward would again be available for service.
At the rate of loss of two to one the squadron would not last long even against the three destroyers that the Commodore thought were left. The Commodore called up the two pilots and asked for a volunteer for what could be a suicide mission, launching a Walrus into the murk of that day. Both men stepped forward and the Commodore selected the more experienced pilot. The Walrus is launched and trundles down the fjord acting as the eyes of the fleet. This pays almost immediate dividends with another ambush point being spotted. The lookout point being blasted, the Hero went past the mouth of the fjord at 30 knots firing two torpedoes, both of which hit the anchored German destroyer, turning it into a sunken wreck. The Walrus had continued down the fjord while the squadron had dealt with the ambush, but found no more ambushes. Reaching Narvik harbour itself the observer sent warning that there were six more destroyers in harbour. It was now that the two heavy cruisers proved their worth being able to use standoff fire outside the range of the German destroyers 5" and using the Walrus to spot for the shoot. The German destroyers made smoke to try to conceal themselves but this was blown away in the windy conditions. Three more German destroyers became total wrecks under the withering fire of the cruisers 7.5" guns. The other three having varying degrees of damage. It was at this point that the missing two German destroyers made an appearance firing torpedoes and guns at the cruisers. A lucky torpedo hit on the Kent forced the remains of the ILS squadron to withdraw. While damaged the Kent was still able to make 15 knots. So ended the First Battle of Narvik.
Offshore the weather started abating in the afternoon allowing the Apollo to launch reconnaissance aircraft. These aircraft surveyed the Narvik fjord system and noted the survivors of the Hardy. The remaining 5 damaged German destroyers were all in Narvik Harbour. The aircraft sent to the north spotted the Scharnhorst and Gneisenau returning from destroying the weather station on Spitzbergen to support the destroyers in Narvik. Having seen they were spotted and having lost the advantage of surprise and not knowing what was facing them, the S&G followed their main orders and reversed course heading for the passes out into the Atlantic. A strike force was sent out after S&G but was unable to locate them before dusk. This left the dive bombers and a few fighters to attack Narvik. The Hero was sent in to retrieve the Hardys survivors. The Narvik air strike force met with heavy covering fire from the destroyers and the troops the destroyers had landed. Despite this two more destroyers were sunk and two more heavily damaged. Of the original ten German destroyers, only one effective unit remained. An eventual decisive victory to the British forces.
At this point having spent almost two weeks at sea the ships of Admiral Whitworths fleet were withdrawn to the Faeroes where replenishment ships were waiting for them. During this passage the Apollo was torpedoed by a U-Boat. Heavy damage and listing was not aided by a crew that had only been together for six weeks. The ship was righted and being down by the stern was taken in tow by the Surrey and with three destroyer escorts, headed for Rosyth and the safety of a dockyard. This first service period of the Apollo had netted the damage to the Hipper, the sinking of the destroyers in Narvik, and while the ship is in for repair, the ships Skua dive-bombers finish off the damaged Hipper, sinking it with a further 5 bomb hits.
More instalments to come on the service life of the Apollo.
