Bombardment of Yarmouth and Lowestoft

Recruitment poster making the most of reaction to German air raids

In February 1916, Admiral Reinhard Scheer became commander-in-chief of the German High Seas Fleet and commenced a new campaign against the Royal Navy. A principal part of his strategy was to make raids into British waters to lure British forces into battle, in conditions advantageous to the Germans.[1] A proposal was made to bombard towns on the east coast of England at daybreak on 25 April, which along with air raids by Zeppelins the night before, would provoke British ships to respond.[2] The raid was timed to coincide with the expected Easter Rebellion by Irish Nationalists, who had requested German assistance.[3]

Immediately before the raid, the German Navy believed that the British had a strong force in the North Sea, off Norway and another at Hoofden and off the south-east coast of England. The Germans intended to sneak out between the two forces to bombard the English coast and then attack whichever British force showed first. With luck, the German battlecruisers could engage the south-east force and after defeating it would run back to the north-west, meeting the northern group in the area around Terschelling Bank. Here the battlecruisers would attack the second British group from the south and the main body of the High Seas Fleet would attack from the north. If successful, the High Seas Fleet would be able to destroy significant elements of the British fleet before the main body of the British Grand Fleet could assist, reducing or eliminating the Royal Navy's numerical superiority. If the British did not take the bait, then merchant ships could be captured and British units off the coast of Belgium destroyed.[2]

The forces sighted by Germany in the North Sea had been part of a raid launched on 22 April, to draw out the German fleet but this did not go to plan. The battlecruisers HMAS Australia and HMS New Zealand had collided in fog off Denmark, causing serious damage to both ships. Later, the battleship HMS Neptune collided with a merchant steamer and three destroyers were also damaged in collisions. The mission had been abandoned and the ships returned north to port, so that on 24 April the main body of the Grand Fleet was near its home bases of Rosyth for the battlecruiser squadron and Scapa Flow for the remainder of the Grand Fleet.[4]

Lowestoft and Great Yarmouth were selected as the targets of the German bombardment. Lowestoft was a base of operations for minelaying and sweeping, while Yarmouth was a base for the submarines that disrupted German movements in the Heligoland Bight. The destruction of the harbours and other military establishments of both towns would assist the German war effort, even if the raid failed to bait the British heavy units. Eight Zeppelin airships would, after dropping their bombs, provide reconnaissance for the battlecruisers, which would conduct rescue operations, should an airship be lost over the water. Two U-boats were sent ahead to Lowestoft, while others were stationed off, or laid mines in, the Firth of Forth, Scotland.[2]

The 1st Scouting Group, consisting of the battlecruisers SMS Seydlitz, Lützow, Derfflinger, Moltke and Von der Tann (Rear-Admiral Boedicker), would be supported by the four light cruisers of the 2nd Scouting Group and the fast torpedo boat flotillas VI and IX, with their two command light cruisers.[5] The Main Fleet, consisting of Squadrons I, II and III, Scouting Division IV and the remainder of the torpedo flotillas, was to accompany the battlecruisers to the Hoofden, until the bombardment was over, to protect them against superior enemy forces.[2]

SMS Seydlitz, which struck a mine and had to return to harbour

At noon on 24 April, German forces were in place and the operation began. The route led around British minefields to the English coast and was intended to put the bombardment group off Lowestoft and Yarmouth at daybreak, where they would bombard the towns for 30 minutes. At 16:00, the battlecruiser Seydlitz—in the vanguard of the reconnaissance force—struck a mine just north-west of Nordeney, in an area swept the night before. She was forced to turn back with a flooded torpedo compartment from a 50 ft (15 m) hole on the starboard side, being only able to make 15 kn (17 mph; 28 km/h) with 1,400 short tons (1,300 t) of water on board and 11 men killed.[3] While the rest of the squadron was stopped for Boedicker to transfer to Lützow and for Seydlitz to escape the minefield, the German ships sighted and avoided torpedoes from one or more British submarines. Seydlitz returned to the river Jade, accompanied by two destroyers and Zeppelin L-7. To avoid other possible mines and submarines, the battlecruiser force altered course to a route along the coast of East Friesland. This had previously been avoided, because in the clear weather the ships risked being sighted from the islands of Rottum and Schiermonnikoog and their movements reported to the British. It was assumed that the British would now be alerted to the movements of the German ships.[2]

The British already knew that the German fleet had sailed at midday. More information arrived at 20:15, when an intercepted wireless message gave the information that they were headed for Yarmouth. At 15:50, the British fleet had been placed on two hours readiness and at 19:05 were ordered to sail south from Scapa Flow. Around midnight, the Harwich Force (Commodore Reginald Tyrwhitt) of three light cruisers and 18 destroyers was ordered to move north.[5]

Around 20:00, German ships received a message from the Naval Staff, that a large British fleet was operating off the Belgian coast and that another large force had been sighted off Norway on 23 April. This suggested that the British Fleet was still divided, giving rise to optimism that the operation would go off as planned, despite the mining of Seydlitz. At 21:30, another message indicated that British patrol boats off the Belgian coast were heading back to harbour, which was interpreted as confirmation that British submarines had reported the German movements.[2] By 24 April the northern British ships had returned to harbour for coaling and were unaware of the moves.[6] The ships off the Flanders coast included 12 additional destroyers from the Harwich Force, which had been sent to assist with a barrage of the coast.[5]

SMS Rostock sighted British destroyers approaching.

The German airships, having dropped their bombs, returned to the bombardment force. Visibility over land was poor, the winds were unfavourable and the towns were better defended than had been thought. The Zeppelins that had bombed Norwich, Lincoln, Harwich and Ipswich had been fired on by British ships but none had been damaged. At about 03:50, the light cruiser SMS Rostock, one of Boedicker's screen ships, sighted British ships in a west-southwest direction.[2] Tyrwhitt reported the sighting of four battlecruisers and six cruisers to the Grand Fleet. He turned away south, attempting to draw the German ships after him away from Lowestoft but they did not follow. The four battlecruisers opened fire upon Lowestoft at 04:10 for 10 minutes, destroying 200 houses and two defensive gun batteries, injuring 12 people and killing three. The ships then moved off to Yarmouth but fog made it difficult to see the target. Only a few shells were fired before reports arrived that a British force had engaged the remainder of the German ships and the battlecruisers broke off to rejoin them.[7][8]

HMS Conquest: hit by shell fire

When he found he could not draw the German ships away, Tyrwhitt had returned and engaged the six light cruisers and escorts but broke off the action when seriously outgunned when the battlecruisers returned.[9] The light cruisers Rostock and Elbing had tried to lead the British ships into the waiting guns of the battlecruisers but upon sighting the German capital ships, the British cruisers turned south. The German battlecruisers opened fire, causing severe damage to the cruiser HMS Conquest, the destroyer HMS Laertes and slightly damaging one light cruiser. Conquest was hit by a shell, which reduced her speed and produced 40 casualties. Boedicker failed to follow the retreating ships, assuming they were faster and probably concerned whether other, larger vessels might be about.[9] The Germans ceased fire and turned north-west towards the rendezvous off Terschelling Bank, hoping the British cruisers would follow, which they did not.[2]

During the bombardment of the two coastal towns, the light cruiser SMS Frankfurt sank an armed patrol steamer, while the leader of Torpedo-boat Flotilla VI, SMS G41 sank the trawler King Stephen, of the earlier King Stephen Incident. The crews were rescued and taken prisoner and around 07:30, the German Naval Staff passed on reports from Flanders of intercepted wireless transmissions instructing British ships to coal and then proceed to Dunkirk.[2] Tyrwhitt attempted to follow the German squadron at a distance. At 08:30, he had located smoke from the ships, but was ordered to abandon the chase and return home. The Grand Fleet had encountered heavy seas and made slow progress coming south, leaving its destroyers behind because of the weather. At 11:00, the Admiralty ordered the chase to be abandoned, at which point the main part of the fleet was 150 mi (130 nmi; 240 km) behind the British battlecruiser squadron, which had started out from further south. The two battlecruiser squadrons came within 50 mi (43 nmi; 80 km) of each other but did not meet.[10]
