Londonderry (War of the Revolution).
This town in which the Ulster Protestants, to the number of about 30,000, had taken refuge, was besieged by James II, April 19, 1689. It was defended by about 7,000 armed citizens, under Major Henry Baker, and held out until July 30, when Colonel Kirke succeeded in forcing the boom at the head of Lough Foyle and reprovisioning the town. The besiegers then withdrew, having lost 5,000 men during the siege. The garrison was reduced to 4,000. Among those who died during the siege was Major Baker.
