The Southampton (Hampshire) Trained Bands of 1638 consisted of 4,799 men armed with 2,854 muskets and 1,945 corslets (body armour, signifying pikemen). They also mustered 170 horse.
In 1639 Trained Bands of the Isle of Wight (then part of Hampshire) were alerted by the presence of a Spanish fleet in the Channel, but had little armament due to detachments sent to the King's army in the North. Sir John Leigh, a supporter of Parliament, was colonel of the Isle of Wight militia from 1642 to 1647.
In 1642 the Hampshire Trained Bands supported Sir William Waller's Parliamentarian forces at the siege of Portsmouth and probably that of Southsea Castle.
