 FACT: The Battle of Naseby takes place in 1644, before the creation  of the New Model Army, and Cromwells Parliamentarian troops are  heavily outnumbered by the Kings Army. In reality, the Battle of  Naseby was in 1645, the Parliamentarian troops were represented by  the newly formed New Model Army which had a substantial advantage in  numbers (some 13,000 to the Kings 7400), and Sir Thomas Fairfax,  not Cromwell, was in command.
