- Pontefract Castle 17th Century
- 1645 - On 22nd April, the Scottish troops aiding the Parliamentarians marched away through the Park and were replaced by troops commanded by Sir John Savile. From this time, the besiegers regularly brought up parties to Baghill putting them behind hedges and in trenches. Keeping a constant watch on the garrison, they poured in their shot and opened fire at every available opportunity, which the besieged, in like manner, returned. In these attacks, lives were lost on both sides but it does not appear that the besieged Royalists were ever able to sally beyond the enemy's positions as, from this time, they were completely surrounded.
