Sir Arthur Haselrig is another prolific commander of cavalry – this time on the Parliamentarian side. He raised a troop of horse for the Earl of Essex and fought alongside them at Edgehill. His cuirassiers became known as the London Lobsters, who were probably the last unit to fight on English soil in full armour.
Haselrig and his lobsters distinguished themselves at Lansdown, but it was at Roundway Down that they gained true notoriety. They proved to be impervious to both pistol-shot and sword blow, only faltering when the royalist cavalry attacked their unarmoured horses!
