There was a deep, rolling boom from his left and he and his staff glanced towards the harbour as a salvo of heavy cannon fire crashed out from the lighthouse mole.
‘What the hell?’ Berthier muttered.
‘Concealed battery,’ Napoleon muttered as he swung his telescope towards the mole and saw the muzzles pointing out through the makeshift breastwork that the defenders had erected at the start of the siege. They must have moved the guns up the previous night, to enfilade the French attack, he realised. As he watched the enemy gunners reload he saw that they weren’t Turks, but sailors from the British fleet. Then it struck him. ‘Those are our captured siege guns!’
He lowered his scope and glanced down the slight incline towards the French batteries. Whoever was in charge of the sailors knew his business; within a few shots they had the range of the nearest of Napoleon’s batteries and the heavy balls tore through the earthworks and smashed into the weapons beyond. The crews did not have a chance and were mown down along with their guns. After a few more rounds there was a short pause before the English trained their cannon on the next target and opened fire.
Napoleon turned his attention back to the desperate charge across the open ground. The first men had reached the city’s defences and were struggling to lean their ladder up against the wall beneath the breach. The top rung was some distance below the gap and even as the first man scrambled up Napoleon realised that the engineers had miscalculated. Reaching the top of the ladder, the soldier valiantly stepped on to the top rung, and flattened himself to the masonry while his hands groped up towards the lip of the breach. The distance was too great, and as Napoleon and his staff watched in silence, willing the man on, a Turk leaned out from the bastion, took careful aim, and shot the French soldier in the back. He spasmed, arched and tumbled off the ladder on to his companions below. As the sailors’ guns knocked out the batteries on the left flank, the assault on the defenders began to slacken and all along the wall musket fire poured down on the attackers as they threw their ladders up against the walls only to discover that none of them was long enough. Seeing that his men were being relentlessly cut down, Napoleon shook his head.
‘It’s no good. They’re getting cut to pieces. Sound the recall.’
The moment the notes from the bugles cut across the battlefield the French troops turned and ran for their lives, pursued all the way back to their trenches by musket fire. At the same time Napoleon ordered the guns on his left flank to be abandoned. As the crews hurried out of range the British sailors methodically knocked out one battery after another until they ran out of targets, and it seemed as if stillness and quiet returned to the scene, until the combatants’ ears recovered from the numbing effects of the previous din and could pick up the thin cries and shrieks of the wounded and dying men still out on the battlefield.
‘What now, sir?’ Berthier asked quietly as he surveyed the wrecked batteries and the bodies scattered before the walls of Acre.
Napoleon shrugged. ‘Now we have to try something else. We’ll attempt another assault when the sappers have mined that bastion.’
It took another five days for the tunnel to be dug under the foundations of the bastion.The engineers packed the small space with barrels of gunpowder, laid a fuse and withdrew from the tunnel. Once again the approach trenches were filled with assault troops as they waited for the moment to attack. When all was ready, the chief engineer lit the fuse and fell back as it sputtered brightly into the darkness of the tunnel. Every man in the French army watched in tense silence, necks and shoulders strained as they braced themselves against the blast.When it came there was a sheet of flame from the end of the tunnel and the ground at the base of the bastion blew up into the air.A shower of rock, stones, soil and dust shrouded the scene. Napoleon felt the tremor pass through the ground under his feet and then the air was filled with the roar of the detonation.
At once, every man on the staff and the assembled senior officers strained to pick out the detail through the slowly clearing pall of dust. Then a puff of wind from the sea cleared the view and Napoleon’s heart sank. The only sign of damage was the collapse of a stretch of the battlements and a small crack that ran only halfway up the wall.There was nothing for it but to call off the attack, and the men trudged back from the approach trenches to their tents in the camp.
The field guns resumed their bombardment of the wall, with the same dispiriting lack of effect, day after day, until Berthier brought it to Napoleon’s attention that their stock of ammunition was running dangerously low.The next day the army headquarters issued a proclamation offering a bounty on any enemy cannon balls that could be retrieved from the ground in front of the walls. Those men who still had enough spirit of adventure amused themselves with daring sprints from their trenches to grab the nearest ball and then hurry back to safety before the Turks could respond with a fusillade of musket fire.A few did not make it, but the steady flow of recovered shot went some way towards supplementing the dwindling supplies in the army’s stores.
The replacement siege guns were landed at Haifa in the middle of April and hauled overland to the siege lines. New, better protected, batteries were constructed on the right flank, and sweating crews manoeuvred the heavy guns into position and brought up the powder and shot ready for the renewed attack on the bastion. They opened fire on the last day of April and Napoleon noted with satisfaction that they were immediately having an effect. Each heavy ball smashed into the city’s defences, dislodging a small fall of masonry. Within a day a practical breach had been opened and the French army prepared itself for another attack.
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—’
