There was a dull clatter from beyond the timbers and then they began to swing inwards. Arthur had a glimpse of armed men under the gate tower, then the sergeant swept his portfire down on to the paper cone of the fuse. Even as it flared briefly, Arthur felt a cold fist clench in his stomach, but it was too late to do anything. The gun went off with a boom as a jet of flame and smoke gushed through the pettah gatehouse. Colonel Wallace thrust his sword out and shouted to his men. ‘Forward! Forward, you devils!’

Arthur dismounted and pushed his way through the men and under the gatehouse. The cannon had gone off right in the faces of some of Vesey’s sepoys. One man, who must have been directly in front of the muzzle, had been torn in two and his head, chest and shoulders lay several feet from his pelvis and buckled legs. In between, his guts and pools of blood lay spashed across the ground. Several more men were injured and were staggering out of the way of Wallace’s soldiers as they charged into the town. Beyond them Arthur caught a glimpse of a handful of the Arab mercenaries disappearing into one of the narrow streets.Then he saw Vesey and indicated the injured men.

‘Have them taken back to our lines to get their wounds tended.’

‘Yes, sir.’Vesey saluted.

‘By the way, Captain.’ Arthur clapped him on the shoulder. ‘That was fine work.’

‘Yes, sir. Thank you, sir.’

Arthur drew his sword and entered the base of the gatehouse. He stepped over several enemy bodies on the stairs as he made his way up and emerged on to the paved top of the bastion where the grenadier officer had carved a path through his enemies. The small area was littered with the bodies of the mercenaries, all killed by savage sword blows or thrusts from the bayonet. Amongst the dead were two of the grenadiers, and a third, injured, man was slumped against the inside of the rampart clasping his hands over a wound to his stomach. As he saw his general he raised a bloodied hand to salute. For an instant, Arthur felt a compulsion to tend to the man, but compassion was a luxury a commander could not afford until after the battle. So Arthur returned the salute and made his way to the breastwork to look over the town.
