Parliamentarian cavalry- Parliamentarian cavalry on the right side of the battlefield charge towards the Royalist cavalry- these troops were called the ironsides and were well equipped, well trained and well disciplined. They were Parliament's best troops- the ironsides used swords and pistols against the Royalist cavalry, who they defeated and chased off- Cromwell regrouped the cavalry and led them against the flanks of the Royalist infantry, which began to collapse.- The royalist cavalry had ridden off to loot the parliamentary baggage train at the back of the battlefield and didn't return for an hour, this was mostly due to poor leadership from Prince Rupert. It may have also been the case that a signal was misinterpreted and the cavalry believed that they had to leave the battlefield
