‘Yes, sir.’ Fitzroy saluted and spurred his mount forward towards the ranks of men marching up to the right side of the pettah’s gate, which Wallace’s column was boldy approaching, dragging a six-pounder cannon with them. Once Fitzroy had passed on the warning the right-hand column split into two as they made for the bastions at each end of the length of wall assigned to them.

Arthur pulled out his telescope to watch the progress of the attack as closely as possible. One of Harness’s grenadier officers had rallied some of his men and they had moved towards the nearest bastion and thrown up a ladder. The first three men and the officer hurriedly began to climb. As they neared the top a handful of defenders suddenly appeared and thrust the ladder away with poles so that it toppled back, throwing the climbers on to the ground. At once the officer was up on his feet. His hat had been knocked off and a livid red streak ran down his face from an injury in his scalp. He helped his men replace the ladder, and while the skirmishers turned their fire on the defenders above he raced back up the ladder, followed by his men. He didn’t pause at the top. Drawing his sword as he reached the rampart, he clambered across the battlements and fell upon the Arabs in the bastion. His sword flashed brilliantly as he carved a path through his enemies.The grenadiers surged up the ladder and joined him to clear the top of the bastion. The struggle was brief as more grenadiers piled into the fight and then disappeared into the bastion. Colonel Harness was hurriedly directing his men towards the place and they began streaming over the top as the distant pop and crackle of musket fire sounded over the pettah walls.

Over on the right Vesey’s men had reached another bastion and were locked in a desperate fight with its defenders.With two bastions out of action Colonel Wallace faced little danger as the central column waited on the track before the main gate. Ahead of them the six-pounder had been loaded and the artillery crew was running it up to the gate so that the muzzle pressed against the stout but aged timbers.

Arthur spurred Diomed forward to join the men waiting to assault the town. He was determined to be there when they did enter to make sure that the officers restrained their men from looting or attacking the civilians within the walls. As he rode along the column towards the gate an artillery sergeant carrying the portfire suddenly shouted. ‘Back, lads! They’re opening the gates!’
