The relief of Derry by William Sadler in the Ulster Museum - The relief force, under command of General Kirke, arrived on 11 June 1689 in full sight of the desperate and starving city. The relief force made camp on Inch Island and stayed there for six weeks. An angry order from the Duke of Schomberg set the relief of Derry in motion. Finally, in the evening of 28 July 1689 three vessels, the Phoenix, the Jerusalem and the Mountjoy, broke through the boom of logs and chains in the River Foyle. Helped by the high tide and partying, thus drunk, Jacobite cannoneers the vessels supplied the city with food and ammunition. Realising the siege was over the Jacobites withdraw and the Siege of Derry ended 105 days after it had began. 固opFoto
