Battle of Jutland

German Empire achieves undecisive victory in the naval battle against British Empire.

The fleet of the German Empire was created with being a threat to the British domination on the seas in mind... and managed to achieve it. It was numerous, and with its mariners and officers competent. It had 16 pre-dreadnoughts compared to 28 pre-dreadnoughts on British side... but that was enough to remain a threat and tie a most of British Navy on the North Sea.   Finally the fleet got tired with the 'tying' part. This led to Battle of Jutland. The plan of it was to use several of German battlecruisers to lure away a part of Grand Fleet under admiral sir John Jellicoe and have it face entire might of the German Hochsea Flotte under vice-admiral Scheer. Effectively causing a lot of damage to both British Navy and its international image.   Many things played a role in German victory - but none of them greater than Royal Navy's battlecruisers vulnerability to direct hits (one that penetrated armor) at its artillery towers, that could lead to ammo magazine explosion if necessary measures weren't taken prior to battle. And they weren't, because it was the type of construction errors that can be found only the hard way.   Five out of six battlecruisers of the vice-admiral Beatty were sunk, four of them suffering ammunition explosions. This included his flagship, HMS Lion, that exploded right after the first salvo of the Hochsee Flotte, greatly contributing to the disaster of the initial engagement. Three dreadnoughts that followed his battleship squadron came under heavy fire by the German fleet (British fleet had no idea that they even left their ports, a painful oversight). HMW Valiant suffered crippling damage to its engines by a lucky torpedo, and while rest of the Beatty forces fled the beattle succesfully, it was ultimately abandoned by its crew and sunk after it became the target of 22 pre-dreadnoughts and dreadnoughts.   Later on engagement were mostly inconclusive, with German Empire deciding that it achieved it goals for the battle, and the British Grand Fleet out for revenge - the engagements between dreadnoughts ended with a lot of smaller ships sunk and most of bigger ones suffering at least some damages. Germans played it defensively and managed to safely retreat to their ports.   The battle was a minor victory for German Empire, but an almost crippling disaster to the British Empire. It's world famous fleet suffered defeat of the type was never before seen or even imagined. In terms of strategy, the German Empire achieved nothing - as the containment of its fleet in its ports wasn't broken, and most of its ship requiring long repairs that were a major burden on already burdened German industry. But this didn't change the fact that they humiliated British Empire and dealt a major blow to the Grand Fleet, forcing even bigger part of the Royal Navy to be ready for their eventual second trip out of the ports.
