Charles ignored the advice of general Lord George Murray and chose to fight on flat, open, marshy ground where his forces would be exposed to superior government firepower. He commanded his army from a position behind his lines, where he could not see what was happening. He hoped that Cumberland's army would attack first, and he had his men stand exposed to the British Royal artillery. Seeing the error in this, he quickly ordered an attack, but his messenger was killed before the order could be delivered. The Jacobite attack was uncoordinated, charging into withering musket fire and grapeshot fired from the cannons, and it met with little success. The Jacobites broke through the bayonets of the redcoats in one place, but they were shot down by a second line of soldiers, and the survivors fled. Cumberland's troops allegedly committed a number of atrocities as they hunted for the defeated Jacobite soldiers, earning him the title "the Butcher" from the Highlanders. Murray managed to lead a group of Jacobites to Ruthven, intending to continue the fight. Charles thought that he was betrayed, however, and decided to abandon the Jacobite cause. James, the Chevalier de Johnstone, acted as Aide de Camp for Murray during the campaign and briefly for Charles himself, and he provided a first-hand account of these events in his "Memoir of the Rebellion 1745–1746". Charles's subsequent flight is commemorated in "The Skye Boat Song" by Sir Harold Edwin Boulton and the Irish song "Mo Ghile Mear" by Seán Clárach Mac Domhnaill. He hid in the moors of Scotland, always barely ahead of the government forces. Many Highlanders aided him, and none of them betrayed him for the £30,000 reward. Charles was assisted by supporters such as pilot Donald Macleod of Galtrigill, Captain Con O'Neill who took him to Benbecula, and Flora MacDonald who helped him escape to the Isle of Skye by taking him in a boat disguised as her maid "Betty Burke". He ultimately evaded capture and left the country aboard the French frigate "L'Heureux", arriving in France in September. The Prince's Cairn marks the traditional spot on the shores of Loch nan Uamh in Lochaber from which he made his final departure from Scotland. With the Jacobite cause lost, Charles spent the remainder of his life on the continent, except for one secret visit to London.
