The 55-year-old Scarlett quickly assembled just 300 of his Inniskillings and Scots Greys (of Waterloo fame) at the foot of the heights, organising them into parade-perfect formation, and sounded the charge. As astounded onlookers watched from the rear, Scarlett led his red-clad Heavies into the centre of the grey mass of Russians. His attack was soon followed by rest of the column (the remainder of the Inniskillings and the 4th, and 5th Dragoon Guards). Even the two squadrons of 1st Royal Dragoons who had remained behind to hold the Brigade's original position attacked on their own initiative. This action became known as the Charge of the Heavy Brigade and caused the enemy formation to collapse completely. The Russians were routed and retreated across the heights into the valley that shortly after would become so infamous. Although successful, it defied military doctrine of the time, as the Russians were more numerous and, more importantly, the charge was made uphill against an oncoming force.
