I attempted to arrest five members of parliament. When this failed he fled the city, and Parliament retaliated by removing Sir John Byron, the Lieutenant of the Tower. The Trained Bands had switched sides, and now supported Parliament; together with the London citizenry, they blockaded the Tower. With permission from the King, Byron relinquished control of the Tower. Parliament replaced Byron with a man of their own choosing, Sir John Conyers. By the time the English Civil War broke out in November 1642, the Tower of London was already in Parliament's control. The last monarch to uphold the tradition of taking a procession from the Tower to Westminster to be crowned was Charles II in 1661. At the time, the castle's accommodation was in such poor condition that he did not stay there the night before his coronation. Under the Stuart kings the Tower's buildings were remodelled, mostly under the auspices of the Office of Ordnance. Just over £4,000 was spent in 1663 on building a new storehouse, now known as the New Armouries in the inner ward. In the 17th century there were plans to enhance the Tower's defences in the style of the trace italienne, however they were never acted on. Although the facilities for the garrison were improved with the addition of the first purpose-built quarters for soldiers (the "Irish Barracks") in 1670, the general accommodations were still in poor condition. When the Hanoverian dynasty ascended the throne, their situation was uncertain and with a possible Scottish rebellion in mind, the Tower of London was repaired. Most of the work in this period (1750 to 1770) was done by the King's Master Mason, John Deval. Gun platforms added under the Stuarts had decayed. The number of guns at the Tower was reduced from 118 to 45, and one contemporary commentator noted that the castle "would not hold out four and twenty hours against an army prepared for a siege". For the most part, the 18th-century work on the defences was spasmodic and piecemeal, although a new gateway in the southern curtain wall permitting access from the wharf to the outer ward was added in 1774. The moat surrounding the castle had become silted over the centuries since it was created despite attempts at clearing it. It was still an integral part of the castle's defences, so in 1830 the Constable of the Tower, the Duke of Wellington,
