There were a lotof private armies given that most ofthe gentry could raise a force intheir command, and then allythemselves to whichever causetheywished in the Civil War - many men found themselves onthe wrong side - when Lord Kilpont in Scotland started out for the Covenenters, and then changed sides to serve Montrose , he tried to take his men with him, but one man rebelled and killed him and went back to the Parliament side, - such mutinies were common - many soldiers found themselves given no food or pay and reacted accordingly - The New Model was disciplined enough and drew enough different armies together underone banner to avoid that - though Cromwell and fairfax did face the Leveler rebellion when John Lillburne tried to do away with rank and priveledge in favourof an equal footing democratic army. The oter armies were town trained band groups in many major towns, - a civil defence team drawn to the attack - manywere reluctant to fight outside oftheir own neighborhoods though asthe war advanced, they were forced into it.
