A cannon roared from the corner of the square and sent a blast of grapeshot scything through those at the head of the charge, bringing down several horses and their riders. Close to Napoleon a musket went off and he cupped a hand to his mouth and bellowed,‘Wait for the order! Don’t fire until they are within fifty paces!’

The sergeants relayed the order along the line and the men stood still in grim anticipation as they watched the approaching enemy, so close now that their wild cries could be heard above the drumming of hooves. From behind Napoleon there came a flat thud as a mortar was fired and the shell arced up and then plummeted down amid the enemy before exploding with a great flash and a roar. A pall of smoke and dust filled the air. For a moment the charge faltered and then the colonel of the brigade bellowed the order to open fire and a hail of musket balls added to the slaughter. Men and horses went down like skittles, and still they came on, desperate to get close enough to use their pistols on the French. Only a few managed it and hurriedly discharged their weapons. Most shots went high, or kicked into the sand at the feet of Napoleon’s soldiers.Then the Mamelukes wheeled their mounts away and spurred them out of range of the French weapons so that they could reload and charge again.

Within minutes the ground in front of the square was scattered with the bodies of horses and riders, many writhing as their cries of agony split the air. Still the muskets roared out, cutting even more of the enemy down. Despite their desperate bravery the Mamelukes could not stand up to the withering fire from the French line, and at last they wheeled their mounts away from Napoleon’s formation and galloped across the rear of Reynier’s and Desaix’s divisions to fall upon the artillery battery on the far right of the line. As soon as the artillery crews saw the threat they abandoned their guns, clambered up on to the flat roofs of the village and fired down on the horsemen swirling between the houses.

Once he saw that the flank would hold off the enemy’s cavalry host, Napoleon turned to Berthier with a grin. ‘We seem to have got their attention on the right. Now’s the time to strike at Embabeh and close the trap.’

He wheeled his horse about and galloped back across the centre of the square. Followed by Berthier and a handful of mounted guides, he made his way through a narrow gap between two battalions of the brigade stationed on the left of the division. They made for the bank of the Nile where General Bon and his men were standing ready to assault Embabeh. Napoleon thrust his arm out towards the earthworks encircling the village.

‘Now’s the time, Bon! Send your men in.’
