I think this is about 1818. Besieged during the Civil War.
From the wiki. See pics of the reenactment in 73 hereNunney Castle continued to be owned by the Roman Catholic Prater family into the 17th century.[25] In 1642 the English Civil War broke out between the rival factions of Parliament and the king; like many Catholics, Colonel Richard Prater supported Charles I.[25] As the war progressed the Royalist situation deteriorated, however, and the south-west became one of the few remaining Royalist strongholds; Nunney Castle was garrisoned in anticipation of Parliamentary attack and took in a number of refugees, including many Catholics.[25][26] In September 1645 a Parliamentary army under the command of Lord Fairfax and Oliver Cromwell advanced into Somerset, taking Sherborne, Cary and Shepton Mallet before turning to Nunney.[25] Two regiments of soldiers with cannons surrounded the castle on 18 September; when Richard Prater refused to surrender, the cannons opened fire on the north side of the castle, breaching the castle wall.[25] Richard continued to resist, hoisting a flag with a Catholic crucifix on it above the castle to taunt the besiegers, but two days later the garrison surrendered.[25]
