In those first few days of May the increasingly weary French battalions launched one assault after another, only to be repulsed by the Turkish troops, who fought with a tenacity that the French had not encountered before. There were severe losses on both sides. General Bon was shot dead in the breach as he urged his men forward, and the irrepressible General Lannes was wounded, once again, as he and two companies of grenadiers managed to break into the city, only to discover that Ahmad Pasha’s men had built an inner line of defences.

In the middle of the month Napoleon called his senior officers to a meeting in his tent late in the evening. He watched as they filed in through the flaps and quietly took their seats.The strain and exhaustion of the last sixty days was etched into their faces, and even before he asked them for their views Napoleon knew that the fight had gone out of them and he would have to perform a miracle to persuade them that Acre could be taken. The trouble was, he felt as bitter and tired as they did and he was momentarily tempted to break off the siege and return to Egypt without even asking for their assessment of the army’s chances. Then some inner reserve of determination stirred in him and he resolved to try to persuade them that the fight could yet be won.

‘Gentlemen . . .’ Napoleon smiled faintly. ‘Friends. Berthier tells me that the men are at the end of their endurance, that some of you are openly saying that we cannot take Acre, and that we must retreat. Does any man here wish to say anything?’

Junot stirred uncomfortably. ‘Sir, it’s been two months and we’re no nearer taking Acre than we’ve ever been.’

‘No nearer? I think you seriously underestimate what we have achieved so far. We’ve breached their walls and must have killed thousands of their men. One last—’

‘Sir,’ Lannes interrupted. He wore a bloodstained dressing around his head and looked pained and drawn as he spoke.‘They have built an inner wall. I’ve seen it. We’d have almost as much difficulty overwhelming that as we did the outer wall. And what does it matter how many of them we kill? Yesterday - we all saw it - a flotilla of ships dropped anchor out to sea and they’ve been ferrying in fresh supplies and troops all through the night and the following day. Sir, I’d follow you anywhere, you know I would. But this is a fight we cannot win.’
