I of England and a diamond ring which Mary swore to wear. Anne's husband was reluctant to lead the rebellion, whose aim was to depose Queen Elizabeth and replace her with the imprisoned Mary, Queen of Scots, whom Catholics regarded as England's legitimate queen; however, he was soon persuaded after his servants informed him that his enemies were surrounding him. He and Anne fled to Branspeth, the home of the Charles Neville, 6th Earl of Westmorland, who was also persuaded to take up arms against Queen Elizabeth. It was at Branspeth where the rebellion began, headed by the two earls. Henry Carey, 1st Baron Hunsdon, who headed a detachment of royal troops sent by the Queen to quell the rising, reported that Anne, who was pregnant at the time, had been "stouter than her husband", and rode "up and down with the army". Her preganacy suggested a plan for the escape of Mary, Queen of Scots from Wingfield Manor. Christine Hogg, the wife of the queen's embroiderer Bastian Pagez was pregnant, and her child was born in November 1569. Later, the Earl of Shrewsbury wrote that Mary Queen of Scots had planned to escape after the birth, dressed as Christine Hogg's midwife or nurse. The midwife's part would have been played by the Countess of Northumberland, because she and the queen were "something like in personage". The Northumberlands were staying near Wingfield at nearby Wentworth House. Exile The Northern Rebellion failed due to its poor planning and lack of proper organization. After the insurrection was put down by Baron Hunsdon's troops, Anne and Percy fled to Scotland, where they sought refuge with Hector Graham of Harlaw, a Border outlaw. In January 1570 she stayed at Ferniehirst Castle and Hume Castle. In June 1570, Anne gave birth to her daughter, Mary in Old Aberdeen. When Graham betrayed her husband to James Douglas, 4th Earl of Morton, she and her baby escaped to the Continent, arriving in Bruges on 31 August 1570, where she sought aid from Pope Pius V and King Philip II of Spain to raise money for her husband's ransom; the Pope gave her four thousand crowns and King Philip sent her six thousands marks. It was to no avail. Anne would spend the rest of her life as an exile in Flanders, while in 1572, Earl Morton sold her husband to Queen Elizabeth who had him publicly executed
