The Second Battle of Newbury on 27 October 1644 was a major battle during the English Civil Wars (1642-1651). There was no clear winner despite the Parliamentarians having a numerical advantage of 2:1. The seeming lack of coordination between the Parliamentarian commanders at Newbury and the definite lack of progress in destroying the royal army led to Parliament forming a new professional fighting force, the New Model Army, which then prosecuted the war with much more vigour and success.
