from the ship Den Briel, proclaiming "the liberties of England and the Protestant religion I will maintain". William's fleet was vastly larger than the Spanish Armada 100 years earlier: approximately consisting of 463 ships with 40,000 men on board, including 9,500 sailors, 11,000 foot soldiers, 4,000 cavalry and 5,000 English and Huguenot volunteers. James's support began to dissolve almost immediately upon William's arrival; Protestant officers defected from the English army (the most notable of whom was Lord Churchill of Eyemouth, James's most able commander), and influential noblemen across the country declared their support for the invader. James at first attempted to resist William, but saw that his efforts would prove futile. He sent representatives to negotiate with William, but secretly attempted to flee on 11/21 December, throwing the Great Seal into the Thames on his way. He was discovered and brought back to London by a group of fishermen. He was allowed to leave for France in a second escape attempt on 23 December. William permitted James to leave the country, not wanting to make him a martyr for the Roman Catholic cause; it was in his interests for James to be perceived as having left the country of his own accord, rather than having been forced or frightened into fleeing. William is the last person to successfully invade England by force of arms. Proclaimed king William summoned a Convention Parliament in England, which met on 22 January 1689, to discuss the appropriate course of action following James's flight. William felt insecure about his position; though his wife preceded him in the line of succession to the throne, he wished to reign as king in his own right, rather than as a mere consort. The only precedent for a joint monarchy in England dated from the 16th century, when Queen Mary I married Philip of Spain. Philip remained king only during his wife's lifetime, and restrictions were placed on his power. William, on the other hand, demanded that he remain as king even after his wife's death. When the majority of Tory Lords proposed to acclaim her as sole ruler, William threatened to leave the country immediately. Furthermore, Mary, remaining loyal to her husband, refused. The House of Commons, with a Whig majority, quickly resolved that the throne was vacant, and that it was safer if the ruler were Protestant. There were more Tories in the House of Lords, which
