Andros swore Phips into his new post in early July, but his council refused Phips' demand that the previously named sheriffs be dismissed. If Phips had simply wanted a share in the spoils of the Dominion, he might have stuck around and kept his head down. Instead he stayed home in Boston only six weeks before shipping back to London to join with Increase Mather in opposing the Dominion and seeking to restore the original charter. This seems to be the first mention of Phips in Increase Mather's diary or correspondence. Motivated by a shared dislike of Andros, Phips and Increase Mather worked together to bring about his downfall. After the Glorious Revolution in late 1688 replaced the Catholic James with the Protestant monarchs William III and Mary II, Phips and Mather petitioned the new monarchs for restoration of the Massachusetts charter and successfully convinced the Lords of Trade to delay the transmission of formal instructions about the change of power to Andros. Phips returned to Boston in May 1689, carrying proclamations from the King and Queen and found Andros and Randolph had already been arrested in a revolt in Boston. Phips served for a time as an Overseer guarding Andros and Randolph in the prison at Castle Island.
