As a matter of fact, after a slight cannonade at the Battle of Turnham Green on 13 November, Essex's two-to-one numerical superiority of itself compelled the King to retire to Reading. Turnham Green has justly been called the "Valmy of the English Civil War"; for like the Battle of Valmy it was a victory without having to come to battle, and the tide of invasion having reached this far, ebbed and never returned.
