heir. In early 1707 George's hopes were fulfilled when Caroline gave birth to a son, Frederick. In July Caroline fell seriously ill with smallpox, and George caught the infection after staying by her side devotedly during her illness. They both recovered. In 1708 George participated in the Battle of Oudenarde in the vanguard of the Hanoverian cavalry; his horse and a colonel immediately beside him were killed, but George survived unharmed. The British commander, Marlborough, wrote that George "distinguished himself extremely, charging at the head of and animating by his example [the Hanoverian] troops, who played a good part in this happy victory". Between 1709 and 1713 George and Caroline had three more children, all girls: Anne, Amelia, and Caroline. By 1714 Queen Anne's health had declined, and British Whigs, who supported the Hanoverian succession, thought it prudent for one of the Hanoverians to live in England to safeguard the Protestant succession on Anne's death. As George was a peer of the realm (as Duke of Cambridge), it was suggested that he be summoned to Parliament to sit in the House of Lords. Both Anne and George's father refused to support the plan, although George, Caroline, and Sophia were all in favour. George did not go. Within the year both Sophia and Anne were dead, and George's father was king. Prince of Wales Quarrel with the King George and his father sailed for England from The Hague on 16/27 September 1714 and arrived at Greenwich two days later. The following day, they formally entered London in a ceremonial procession. George was given the title of Prince of Wales. Caroline followed her husband to Britain in October with their daughters, while Frederick remained in Hanover to be brought up by private tutors. London was like nothing George had seen before; it was 50 times larger than Hanover, and the crowd was estimated at up to one and a half million spectators. George courted popularity with voluble expressions of praise for the English, and claimed that he had no drop of blood that was not English. In July 1716, the King returned to Hanover for six months, and George was given limited powers, as "Guardian and Lieutenant of the Realm", to govern in his father's absence. He made a royal progress through Chichester, Havant, Portsmouth, and Guildford in southern England. Spectators were allowed to see him dine in public at Hampton Court
