died and Mitchelburne became governor of Derry. On 2 July Rosen herded Protestants from the surroundings to under the wall. The besieged responded by threatening to kill prisoners. Hamilton reported this event to James, who disagreed with Rosen's measure and called him a "barbarious Muscovite". Relief Frederick de Schomberg, having been appointed commander-in-chief by William, ordered Kirke to attack the boom. Thereupon, on 28 July, Kirke sent four ships to the mouth of the River Foyle to try to bring food into Derry. These were HMS Dartmouth and three merchant ships: Mountjoy from Derry, Phoenix from Coleraine, and Jerusalem. Dartmouth, under Captain John Leake, engaged the shore batteries, while Mountjoy, commanded by her Master Michael Browning, rammed and breached the boom, whereupon Mountjoy and Phoenix sailed up to Derry, unloading many tons of food. Seeing that he could no longer starve out Derry and not having enough troops to storm the town, Rosen decided to raise the siege. On 1 August the besieged discovered that the enemy was gone. On 3 August Kirke reported the raising of the siege to London. On 31 July another Jacobite army had been defeated at Newtownbutler by the Enniskilleners. The city had endured 105 days of siege, from 18 April to 1 August. Some 4,000 of its garrison of 8,000 are said to have died during this siege. Commemorations The Siege of Derry, like the Battle of the Boyne, is part of Northern Irish Protestant folklore. The siege is commemorated by two parades: the Shutting-of-the-Gates Parade and the Relief-of-Derry Parade. The shutting of the gates by 13 apprentices, which happened on 7 December 1688, is commemorated each year on the first Saturday of December, dubbed "Lundy's Day". The commemoration is organised by the Apprentice Boys of Derry, a Protestant association. The day usually starts with the firing of one and then three cannon shots, meaning 13, from the walls at midnight on Friday. Then follows the ceremony of the touching of the four original gates: Bishops Gate, Butchers Gate, Shipquay Gate, and Ferryquay Gate. On Saturday, first the members of the Apprentice Boys clubs domiciled outside the walls march to the Apprentice Boys Memorial Hall. Then the assembled members march through the city from the Hall to St Columb's Cathedral where a thanks-giving service is held. After the service, a wreath is laid at the Siege Heroes Mound in the cathedral grounds. Finally, Lundy
