4th September 1914, Thornton Bank.
The sea fog was thick, with no wind to disturb it, 1st Battlecruiser Squadron, comprising HMS Lion, HMS Queen Mary, HMS Invincible and HMS New Zealand were sailing just off the Dutch coast. The ships had been alerted to a German sortie by a patrolling submarine, it had sighted the running lights of the German units as they made their way south hugging as close to the coast as they could whilst not straying into Dutch waters. The sortie itself was unexpected, the Royal Navy was not expecting the High Seas fleet to strike first, and its ships and men had been preparing for a raid of their own, prior to having to hurriedly raise steam and sail for the Belgian coast.
Commodore Keys and Commodore Tyrwhitt had been engaged in detailed planning for an attack on the patrolling German destroyers in the Heligoland Bight. That attack had been postponed by the need to secure the ports of Ostend and Zeebrugge, with the need to keep safe the passage of the many transports which plied the North Sea bringing men and equipment from Britain to Belgium. The plan however had not been rejected; the First Lord was insistent on the need for offensive action against the Germans.
The delay had had several benefits as far as the Royal Navy was concerned with additional ships and training time utilised. One division of First Battlecruiser squadron had been detached south to join the Harwich force, HMS Lion aboard which Beatty flew his flag and her sistership HMS Queen Mary. Along with the two battlecruisers, 1st Light Cruiser squadron had been deployed south.
The plan for the raid had been an attack into the Heligoland Bight by the four battlecruisers, six light cruisers and sixteen destroyers with the support of Keyes Submarines. That plan was now irrelevant, but the planning had not been wasted entirely as it gave Admiral Beatty and Commodore Tyrwhitt options for the upcoming fight.
With the movement of the British Army to Ostend and Zeebrugge, the Royal Navy had responded by deploying 1st Destroyer Flotilla and 7th cruiser squadron to Ostend. The recognition of the importance of Ostend and Zeebrugge combined with Dutch neutrality and the absence of a Belgian Navy, had required some ships be deployed for coastal defence. had ships operating in the area, as their operations base had changed to Ostend in line with the importance of the Belgian Ports.
The pre-dreadnoughts HMS Victorious and HMS Mars along with attached destroyers were making steam to engage the German ships should they divert to raid the East Coast. This motley squadron was based at Grimsby and so was too away and too slow to be able to intervene before the German Ships reached Belgian waters but may be able to intercept the Germans on their return.
The Grand Fleet was already sailing south from Scapa Flow to strike at the High Seas Fleet should they have also emerged from their base.
The German ships sailing south from Wilhelmshaven included SMS Seydlitz, SMS Moltke, SMS Von der Tann and SMS Blucher. They were accompanied by four light cruisers SMS Coln, Mainz, Kolberg and Augsburg, with eight modern V1 class destroyers provided a light escort. The raid had been the brainchild of Admiral Franz von Hipper, he had developed the idea of the raid as a way of damaging the British build up in Belgium.
His plan was a simple one, his ships would sail from Wilhelmshaven, keeping as close to the German coast as possible before skirting Dutch waters, they would brush aside the light forces reported by aerial reconnaissance as being based in the Belgian Ports. They would then fire on the ports destroying as much as possible before sweeping south towards Britain sinking any ships in the area and then retiring back to Germany as quickly as was practical.
Aboard HMS Lion Rear Admiral Beatty was waiting, his ships were making just enough steam to be able to reach full speed quickly whilst still minimising fuel burn. His goal was to engage the German ships at the closest range he could, his battlecruisers would need to close the range only HMS Queen Mary had a working fire control director, HMS Invincible was fitted with the equipment but it was not yet fully operational. His plan was to engage the German fleet with his heavy ships whilst his cruisers and destroyers attacked from the flanks, his orders on that subject were also clear, ships were to deliver their torpedo attacks from the closest range they could.
As he and his fleet at waited the fog slowly lifted, his ships had already come to action stations and as dawn broke reports flooded in of German ships to the Southeast of his position near the Thornton Bank, they were already within range of his ships at 18000 yards.
His orders went out quickly and efficiently, aided by their simplicity “make full steam and engage with all guns that bear”
With that the four battlecruisers settled onto their new course, all four ships in line abreast. Aboard HMS Queen Mary her gunnery director was working effectively, only her forward 2 turrets could fire but already they were tracking the leading German Battlecruiser. They would open fire with the rest of the squadron, aboard the other ships gunnery was down to the individual turrets and so close range was required for any sort of accuracy. Standing orders were too close to 12000 yards prior to opening fire.
The German Battlecruisers showed no such desire to close to close range, they swung slightly to the south to open enable their aft turrets to bear and opened fire.
Their fire was shockingly accurate, HMS Lion was almost immediately struck by a German shell, little damage was done but it was a warning that this battle would be bloody. With first blood to the Germans, Beatty gave the British Battlecruisers the order to open fire, instantly Percy Scott was proven right, German gunnery out-performed that of Royal Navy, with the majority of the British fire proving ineffective. HMS Queen Mary was the single British battlecruiser to be able to boast, her 3rd salvo bracketed SMS Seyderlitz, another followed as quickly as her well trained gunners could load the 13.5” guns. A heavy shell from that salvo smashed through Seyderlitz, piercing her deck armour and deflected downwards penetrated the barbette of a midships turret. The explosion when it came rippled down through the barbette and caused a charge being loaded into the hoist to deflagrate, this spread to ready charges awaiting loading, the resultant fire and explosion burst into the magazine, which detonated tearing her apart.
At almost the same time a pair of German shells did something virtually identical to HMS Lion, within minutes of battle being joined two battlecruisers were destroyed. Aboard HMS New Zealand the gunners had finally got the range of SMS Blucher and were steadily pounding her to pieces. HMS Queen Mary had now taken to firing on SMS Moltke whilst HMS Invincible was exchanging blows with SMS Von der Tann.
The light units of the Royal Navy were having a better time of it, the light cruisers had swung out to the south-east at maximum speed whilst the destroyers had headed east, both groups would attempt torpedo attacks on the German Battlecruisers. The German light units had moved to engage them, outnumbered they were forced onto the defensive. The destroyers were grossly outmatched both in weight of guns available and numbers, the British rapidly sinking six of the eight German vessels for the loss of two before the last two German destroyers broke off trailing smoke and sought the safety of the German battle line. The cruiser fight was more equal but like that of the destroyers it went badly for Germany, three cruisers were soon sinking for the loss of one British cruiser destroyer and one badly damaged.
The torpedo attacks which followed were largely unsuccessful, SMS Blucher was hit twice and slowed to 14 knots allowing HMS New Zealand to complete her destruction. Of the other remaining German ships SMS Von der Tann was hit once slowing slightly but to little other effect and SMS Moltke was saved by the surviving German Cruiser SMS Coln, straying into the path of a pair of torpedos, they detonated breaking her back and sending her to the bottom of the North Sea. The two surviving German Battlecruisers with the Destroyers reversed course and headed for Dutch Waters. Commodore Tyrwhitt, in command following the death of Rear Admiral Beatty, considered his options, signals from HMS Invincible indicated she was badly damaged, with an uncontrolled major fire in B turret.
Tyrwhitt ordered HMS Queen Mary and New Zealand to continue firing on the German ships till they reached Dutch waters but to break off and shadow them they were not to reengage unless the German ships came out to fight. His own flagship, three light cruisers and four destroyers provided an escort for them. The remaining British ships he ordered to assist HMS Invincible’s firefighting efforts or if required evacuation and the search for survivors.
The explosion when it came was shocking, HMS Invincible blew apart, shocked, Tyrwhitt realised that the fire must have been worse than he had thought. The sporadic fire from the fleeing German ships was being matched by the two British battlecruisers, HMS Queen Mary again proving the excellence of her gunnery by striking SMS Von der Tann, at least one shell must have struck her steering gear as she appeared to helm over suddenly, her path now taking her away from the other German ships. HMS New Zealand switched targets and soon both battlecruisers had Von der Tann under fire, as the range closed the shells were striking horizontally. Wreathed in smoke and with her only response fitful fire from her secondary batteries, her companions continued to flee, crossing the invisible line into safety. Tyrwhitt ordered his cruisers to close on the German Battlecruiser and torpedo her, this they did, the ship settled almost gracefully going down on an even keel, the water was shallow where she sank and parts of her upper works remained above water, with German sailors clinging to everything they could to remain safe. Soon the cruisers had dispatched boats to bring the survivors in.
The German survivors increased speed to their maximum and sped to the north-east, Tyrwhitt continued his pursuit with the Battlecruisers and Destroyers, he had been ordered to offer no insult to the Dutch by fighting in their waters and he was content to have the few surviving German ships which had begun this raid flee.
Both the Royal Navy and the German Navy had lost a pair of Battlecruisers and the Germans an armoured cruiser, but the German losses of light ships were catastrophic, four cruisers and six destroyers gone. Compared with British losses of one cruiser HMS Birmingham and two destroyers HMS Lark and HMS Liberty lost and one cruiser HMS Liverpool badly damaged. Almost all of the British ships had some damage apart from New Zealand who had managed to avoid any damage at all.
