(Excerpt): "Marlborough's military career spanned two periods. Aware of the danger of the "exorbitant power of France" and the corresponding danger to the Protestant religion, disgusted with James's actions at the Gloucester shipwreck and in dealing with Scottish Protestants, Marlborough had joined the bloodless shift to William of Orange. For William, he led the English forces in Flanders in 1689 and in Ireland in 1690; in 1691 he was in charge of the British forces in Europe with the rank of lieutenant-general. In January, 1692, however, Marlborough was dismissed from all of his offices for a combination of reasons, each insufficient in itself but all too typical for him—open opposition to William's Dutch dominated army, rumors that he and Sarah, his ambitious and sometimes presumptuous wife, were plotting Anne's usurpation of the throne, and dissension aroused between Anne and her sister Queen Mary by the quixotic Sarah. When rumors of a Jacobite uprising began, Marlborough spent six weeks in the Tower."
