Once again I chose a unit because I think they have a cool flag!
When the first Civil War broke out John Lambert he first proved his worth in Lord Fairfax's Parliamentarian Northern army, showing his tactical ability and bravery whilst fighting at Hull and Nantwich.
His reputation as a soldier steadily increased, and he was second in command when he led his regiment of horse at Marston Moor in 1644. In 1645 he took over Fairfax's position as commander of the Northern Army, but was wounded at Wentbridge later in 1645.
He was second in command to Cromwell at Preston when they crushed the northern resistance at Pontefract. Promoted to Major General, Lambert was Cromwell's second in command when he marched into Scotland in 1650 and temporarily took command when Cromwell fell ill in spring of 1651. Later that year he helped slow the Scottish advance at Preston, before going on to attack Worcester.
The end of the wars found him involved in politics and Parliament nominated him Lord-Deputy of Ireland, but then abolished the post and he refused a lesser position. He supported Cromwell when he dissolved Parliament and wrote the Instrument of Government, Britain's first and only written constitution, to be applied when Cromwell became Lord Protector in 1653. He was a prominent supporter of the Army's power and the creation of the Major Generals who ruled England in 1655. A rift started to form between Lambert and Cromwell and he refused to take the oath of loyalty to the Lord Protector or countenance him as King in 1657. He resigned his commission and retired to his house at Wimbledon with Frances and his ten children to "grow flowers".
