Berkeley Castle 1645
Aug 28 Colonel Morgan, the Governor of Gloucester, surrounds the castle and confines the Royalist garrison under the governorship of Sir Charles Lucas to the grounds preventing them from plundering the nearby countryside.
In discussing terms of surrender, Lucas suggests that the castle is left with no garrison at all, rather than have the castle burnt down and destroyed.
Sep 10 Fairfax captures Bristol. Berkeley Castle is now the only place between Bristol and Gloucester held by the Royalists.
Sep 23 Fairfax sends Colonel Rainsborough with 1000 men who arrives at the castle and summons it to surrender. Sir Charles Lucas replied that he would eat horse-flesh ere he would surrender, and man's flesh when that was done.
A battery of guns was set up to the north east side of town in a field called the Leys. The Church on the north side saw much of the fighting (40 defenders killed and 90 captured) and was eventually captured by the attackers who started preparing to place guns on the roof which overlooked the castle.
Sep 26 Berkeley Castle surrenders. The terms were...the soldiers to march out without arms; the governor, Sir Charles Lucas, with three horses and arms, £50 in money, no more; every field-officer with two horses and £7; foot captains one horse and sword; lieutenants, ensigns, sword and no horse; the field-officers and captains not to exceed £5 the soldiers not 5s.

 

Five hundred men marched out of the gates, and eleven pieces of cannon and six months' provisions fell into the hands of the captors.
Colonel Barrow was appointed Governor of Berkeley Castle to be later followed by Captain William White. The castle was returned to Lord Berkeley after the war on the condition that it was made undefendable. A large breach was made in the north side of the keep.
