Whakaotihia te rerenga e whai ake nei: I whai a Rushworth i te ara o John Pym, i roto i tana korero i te Whare o te Whare i te 17 o Aperira 1640, i whakaeke i te Kingi me tana kawanatanga mo nga raru o roto i te whenua. Whai muri i te pakarutanga o te Pakanga Tangata, ko Rushworth hei "kaituhi whakauru" i whai i nga pakanga o Edge Hill (1642), Newbury (
1643 me 1644), Marston Moor (1644) me Naseby (1645). I te tau 1645 ka noho ia hei kaitiaki ki a Thomas Fairfax, te rangatira rangatira o te New Model Army. I te wa i hopukina ai a Charles I, ka tiimata a Rushworth ki te tuhi taipitopito mo nga huihuinga i mua, i te wa, i muri mai hoki i te whakawakanga me te whakamate i te Kingi. I pūrongo ia i te Pakanga o Preston (1648) me te Pakanga o Worcester (1651).
