Since Walcourt, though, Marlborough's popularity at court had waned. William and Mary distrusted both Lord and Lady Marlborough's influence as confidants and supporters of Princess Anne (whose claim to the throne was stronger than William's). Sarah had supported Anne in a series of court disputes with the joint monarchs, infuriating Mary who included the Earl in her disfavour of his scheming wife. Yet for the moment the clash of tempers were over-shadowed by more pressing events in Ireland where James had landed in March 1689 in an attempt to regain his thrones. When William left for Ireland in June 1690 Marlborough became commander of all troops and militia in England, and was appointed a member of the Council of Nine to advise Mary on military matters in the King's absence; but she made scant effort to disguise her distaste at his appointment – "I can neither trust or esteem him", she wrote to William.
