Example Input: Question: In what year was the man born who captained the HMS Boadicea? Passage:The British eventually recaptured Grappler from the French in September 1809 in the daring raid on Saint-Paul on the Île de Bourbon (now Réunion) from the nearby British-held island of Rodrigues. The British force consisted of a naval squadron under Commodore Josias Rowley and an Army force under Lieutenant Colonel Henry Sheehy Keating. The Army contingent, which consisted of 368 soldiers from the 1st Battalion of the 56th Regiment of Foot under the command Keating, embarked on HMS Nereide under Captain Robert Corbett, Otter under Captain Nesbit Willoughby and the East India Company schooner Wasp under Lieutenant Watkins. The rest of Rowley's squadron, the flagship , and the frigates under Captain Samuel Pym and HMS Boadicea under Captain John Hatley joined off St. Paul. These ships contributed an additional 236 seaman volunteers and Royal Marines to the assault. The entire invasion force then embarked on Nereide, as Corbett had experience with coastline of the Île Bonaparte coastline. On the early morning of 21 September the force seized the port of St. Paul. There they destroyed its defences and recovered a number of British vessels. Nereide and the landing party captured the 44-gun French frigate Caroline, and recovered Grappler as well as the East Indiamen (850 tons (bm) and pierced for 30 guns) and (820 tons (bm) and pierced for 26 guns). The expedition also captured three small merchant vessels (Fanny of 150 tons, and Tres Amis and Creole of 60 tons each), destroyed three others, and burnt one ship that was building on the stocks. The British did not sustain any loss on board the squadron or to their vessels. The British completed the demolition of the different gun and mortar batteries and of the magazines by evening and the whole of the troops, marines, and seamen returned on board their ships.

Example Input: Question: In what year was the commander in chief who sent Elles to investigate the first tanks born? Passage:In August 1915, after recovering from his injuries, Elles was one of three officers specially selected by General Sir William Robertson, soon to be Chief of the Imperial General Staff (CIGS), the professional head of the British Army, to liaise with troops at the front and pass the information directly to the British General Headquarters (GHQ). In January 1916, as a General Staff Officer (GSO), Elles was sent by General Sir Douglas Haig, the Commander-in-Chief (C-in-C) of the BEF on the Western Front, to investigate the first tanks or "caterpillars" being built in England. He attended the first trials of "Mother" and reported back to Haig on its success. During the summer of 1916, he was tasked to report back from the Somme, where the tanks were first used. Elles was appointed to head the Heavy Branch (the first tank units) of the Machine Gun Corps in France on 29 September 1916, with the temporary rank of colonel. His responsibilities included its advanced training and tactical employment. He also commanded the large central depot and workshops established near Bermicourt.
