The First Battlecruiser Squadron was a Royal Navy squadron of battlecruisers that saw service as part of the Grand Fleet during the First World War. It was created in 1909 as the First Cruiser Squadron and was renamed in 1913 to First Battle Cruiser Squadron. It participated in the battles of Heligoland Bight, Dogger Bank and the Battle of Jutland. After the end of the war it became the sole Battlecruiser Squadron.

Formation

The first two British battlecruisers of the Invincible-class battlecruiser—HMS Inflexible (1907) and HMS Indomitable (1907)—were commissioned into the Nore Division of the Home Fleet in October 1908. In early 1909, the Nore Division became the First Division of a reorganised Home Fleet, and Inflexible and Indomitable were transferred to the new First Cruiser Squadron in March 1909; they were joined by their recently completed sister HMS Invincible (1907). Also part of the squadron were the armoured cruisers HMS Minotaur (1906) and HMS Drake (1901) (flagship). Rear-Admiral the Honourable Stanley Colville took command of the squadron on 24 February and transferred his flag to Indomitable on 29 July. Drake then became flagship of the Fifth Cruiser Squadron in the Atlantic Fleet. On 24 February 1911, Rear-Admiral Lewis Bayly assumed command of the First Cruiser Squadron, which had been joined in February by the new Indefatigable-class battlecruiser HMS Indefatigable (1909). Upon joining on 4 June 1912, HMS Lion (1910) became Rear-Admiral Bayly's flagship. HMS Princess Royal (1911) joined on 14 November. A reorganisation of the fleet renamed the First Cruiser Squadron to First Battlecruiser Squadron on 1 January 1913. During 1913 gradually all the older battlecruisers left to join the Second Battlecruiser Squadron in the Mediterranean Fleet. Rear-Admiral David Beatty was selected to command the squadron and succeeded Bayly on 1 March 1913. The near-sister to the Lion-class battlecruiser—HMS Queen Mary—joined on 4 September.

First World War

The First Battlecruiser Squadron at the outbreak of war was composed of the four newest battlecruisers in the Royal Navy. On 3 October, it was joined by the recently completed HMS Tiger (1913). The squadron took part in the successful Battle of Heligoland Bight against the Imperial German Navy on 28 August 1914 and participated in the abortive attempt to engage the Germans during their bombardment of Scarborough, Whitby and Hartlepool on 16 December. On 15 January 1915, New Zealand left to become flagship of the Second Battlecruiser Squadron and was joined by Indomitable, which had served with the First Battlecruiser Squadron over the New Year. The Squadron took part in the Battle of Dogger Bank, where Beatty's battlecruisers forced the Germans to retreat, and in the process sank the German armoured cruiser SMS Blücher, while Lion suffered heavy damage. As a result of the battle, in February the battlecruiser force was reorganised, and a Battlecruiser Fleet (BCF) was incorporated, with Beatty reappointed to command it. Captain Osmond De B. Brock of Princess Royal was appointed Commodore, First Class and given command of the First Battlecruiser Squadron, until he was promoted to the rank of Rear-Admiral in March. At the Battle of Jutland on 31 May 1916, all ships were damaged by German shell fire as the First Battle Squadron under Rear-Admiral Brock and Beatty in Lion lead the British line against the enemy. Early in the action, Queen Mary was lost and all but a small number of her crew were killed. Two other battlecruisers—Invincible and Indefatigable—were sunk during the battle. The squadron's losses were made up for by the arrival of the new battlecruisers HMS Repulse (1916) and HMS Renown (1916) in September 1916 and January 1917 respectively. Brock was replaced by Rear-Admiral Richard F. Phillimore. When Phillimore left to become Rear-Admiral Commanding, Aircraft Carriers, he was superseded by Rear-Admiral Henry Oliver on 14 March 1918.
