Question: What area of England did the duke of Normandy first land on when invading? Passage:In the 11th century, Errand of Harcourt and his three brothers followed William the Conqueror, duke of Normandy, on the Norman invasion of England, and the brothers were installed with English lands. The English Harcourt branch entered the English peerage, as barons then viscounts then earls. At first the Harcourts had lands in Leicestershire, but in 1191 Robert de Harcourt of Bosworth inherited lands of his father-in-law at Stanton in Oxfordshire, which then became known as Stanton Harcourt. The manor of Stanton Harcourt has remained in the Harcourt family to the present day, although from 1756 to 1948 their main residence was at Nuneham House, also in Oxfordshire. Simon Harcourt was created Baron Harcourt in 1711 and Viscount Harcourt in 1721. The third viscount was created Earl Harcourt in 1749, but all titles were extinguished with the death of marshal William Harcourt, 3rd Earl Harcourt, in 1830. His cousin Edward Vernon, Archbishop of York, thus inherited the majority of that branch's lands and titles and took the name and heraldic shield of the English Harcourt family by royal authorisation on 15 January 1831. This created the Vernon-Harcourt branch, descended from a Harcourt woman. The title Viscount Harcourt was created a second time in 1917 for Lewis Harcourt, but the title was again extinguished on the death of his son.

Question: How old was General Sir William Robertson when he selected Hugh Elles to liasise with troops? 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.
