Shortly after returning to Parliament as a Member for Cambridge, in 1642 I took up arms for Parliament. I led one of the earliest military actions of the First Civil War when I led 200 underprepared and under equipped volunteers to prevent the King's men from carrying off the silver plate of the Cambridge colleges. My troop joined the army of The Earl of Essex, and my troop was fighting towards the Battle of Edgehill. In July 1643, I impressed people with my Cavalry commanding skills in the Battle of Gainsbourough. And due to my efforts in securinG East Anglia for Parliament in the summer of 1643, I was appointed Governor of Ely and was also promoted to Colonel in the new Eastern Association Army. I was also named one of the greatest soldiers in England in 1646, despite the fact I had no military experience prior to 1642. Finally, in December of 1653, I made one of my biggest accomplishments in my lifetime. The army wanted me to become king, though I refused it, I was too humble to take the title of king, however, I instead became Lord Protector of the Commonwealth.
