During the English Civil War, Helmsley Castle was besieged by Sir Thomas Fairfax. Sir Jordan Crosland held it for the King for three months before surrendering. Parliament ordered that the castle should be slighted to prevent its further use and so much of the castle's walls, gates and the eastern half of the east tower were destroyed (see right). However the mansion was spared.
In each case there was good reason for destroying the castle before leaving it and allowing it to be re-occupied. But destroying a castle is not easy. Generally it was good enough to do just enough damage to make it not worth while for anyone to repair it. To damage a castle in this way is to "slight" it. By analogy we talk about slighting people too - not desroying them but damaging them.http://www.ecastles.co.uk/york.html
During the Civil War the castle was slighted but it was rebuilt afterwards.http://www.scotwars.com/Ayr_citadel.htm
The Citadels did not survive the Restoration being slighted in the years following an order of the estates in 1660. Slighting or "razing" a fortification usually entailed removing its defensible features (parapets / gun emplacements) and at Ayr this was taken further with the landward fronts being demolished and the ditch filled.http://oxforddictionaries.com/definition/slight

Slighted castles of the English Civil Wars
My primary research area is destruction: how it was carried out, the motives underlying its use, and its overall impact on societies. In particular, I am interested in the deliberate destruction, or slighting, of castles in the English Civil War, and what it tells us about the shifting power dynamics during this period. Conventional wisdom says that the phenomenon of slighting was simply a fiscal and military policy by Parliament ‘to deny use to the enemy’, but the full picture is far more complex. It reveals that castles were targeted for a variety of reasons, in several different ways, and that destruction was often a tool for social, political, religious, and economic control.
