On 18 April 1689, soon after news reached Boston of the overthrow of James II of England, the colonists of Boston rose up against his rule. A well-organized "mob" descended on the city, arresting dominion officials and Anglicans. Andros had his quarters in Fort Mary, a garrison house on the south side of the city, where a number of officials took refuge. The old Massachusetts colonial leadership, restored due to the rebellion and headed by ex-governor Simon Bradstreet, then summoned Governor Andros to surrender, for his own safety because of the mob which they claimed "whereof we were wholly ignorant". He refused, and instead tried to escape to the "Rose", the sole element of the Royal Navy present near Boston at the time of the revolt. However, the boat sent from the "Rose" was intercepted by militia, and Andros was forced back into Fort Mary. Negotiations ensued, and Andros agreed to leave the fort to meet with the rebel council. Promised safe conduct, he was marched under guard to the townhouse where the council had assembled. There he was told that "they must &amp; would have the Government in their own hands", and that he was under arrest. Daniel Fisher grabbed him by the collar and took him to the home of dominion official John Usher and held under close watch.
