Shaw House and its grounds including some Iron Age embankments incorporated into the defences, were defended by Lord Astley, with three "tertias" or brigades of infantry under his son, Sir Bernard Astley, Colonel Thomas Blagge and Colonel George Lisle. Speen was held by Rupert's brother Prince Maurice, with a mixed detachment from the Royalist forces from the west country. Charles's cavalry under George, Lord Goring were in reserve. They were divided into four brigades under Goring himself, Lord Wentworth, the Earl of Cleveland and Sir Humphrey Bennett. The Earl of Brentford was the Lord General, and Charles's deputy Lord Hopton commanded the artillery.
