‘Get me on my feet,’ he muttered to Lannes.

The marshal shook his head. ‘You are injured, sire. I’ll have you carried to safety and send for your physician.’

‘You’ll do no such thing,’ Napoleon snapped. ‘Get me up. Bring me my horse.’

‘As you command.’

The marshal was a powerfully built man and he grasped his Emperor’s arm and raised him up easily. Napoleon stood with all his weight on his left foot and fought to hide any sign of the shooting pain that made an agony of any movement of his right leg. He rested his hand on Lannes’s shoulder as the latter called for his horse. While one of the Emperor’s bodyguard held the reins Lannes carefully lifted Napoleon up into the saddle and placed his right foot into its stirrup. Napoleon took the reins and breathed in deeply.

‘Your orders, sire?’ Lannes looked up at him.

‘Continue the attack, until Ratisbon is taken.’ Napoleon clicked his tongue and touched his heels in as tenderly as he could, wincing at the fiery stab in his right ankle as he did so. The horse walked forward and Napoleon steered it along the front of the regiments forming up for another attack on the enemy defences. Berthier trotted up and drew alongside.

‘Do you wish me to have your carriage brought forward?’

‘No. I will stay on my horse. Where the men can see me.’ Napoleon held up his hand to greet the nearest battalion, and a cheer rose up, loud and prolonged. It was taken up by the next formation and continued down the line of Morand’s division. Napoleon continued riding along the front rank, forcing himself to smile at his men, and exchanging greetings with their commanders as he passed by.

He reached the far end and turned to make his way back. Marshal Lannes had remounted his horse and trotted it forward so that he stood in full view of his soldiers. Napoleon reined in alongside, and forced himself to keep his expression impassive as another cannon ball grounded a short distance from the division’s band, took the head off a young drummer boy and smashed through the chest of the one behind.

Lannes took off his plumed hat and raised it high as he filled his lungs and bellowed, ‘Volunteers for the ladder party step forward!’

His voice resonated briefly in the warm air, then died away, but not a man moved. Those in the front rank stared ahead, refusing to meet the gaze of their marshal or their Emperor. Those who volunteered to carry the ladders would be advancing right behind the skirmishers and the enemy would be sure to concentrate their fire on such easy targets. The ground in front of the Austrian defences was already littered with the dead and wounded of the previous attack and the memory of the storm of fire from the walls was still fresh in the minds of the survivors.

Lannes stared at the silent, still ranks with a surprised look on his face, which swiftly turned to scorn. ‘Is there no man amongst you willing to have the honour of being the first to scale the walls? Well?’

No one moved and Napoleon was aware of a terrible tension building between the marshal and his men. If it was not resolved, and quickly, there would be no second attack. Lannes must have shared the realisation, for he glanced anxiously at his Emperor and then suddenly dismounted and strode towards the nearest of the ladders. As the soldiers looked on, Lannes picked it up and adjusted his position so that he could carry it by himself. He turned towards the men and called out contemptuously, ‘If no man here has the stomach for it, then I’ll do it alone. Before I was a marshal I was a grenadier - and I am still!’

With that, he turned away and began to march towards Ratisbon, the unwieldy ladder held in a firm grip.

‘Good God,’ Berthier muttered. ‘What on earth does he think he’s doing?’

Napoleon could not help smiling. ‘What else? His duty.’

For a moment no man stirred, then one of Lannes’s staff officers ran forward and stood in his commander’s path.

‘Sir! You can’t do this. Who will command the corps if you are killed?’

‘What do I care?’ Lannes growled. ‘Out of my way, damn you.’

He brushed the officer aside and continued towards the waiting Austrians. The other man stared after him, aghast. Then, recovering his wits, he hurried to catch up, took hold of the end of the ladder and fell into step with Lannes.

‘Wait, sir!’ one of the other staff officers called out as he and his companions ran forward, snatched up the nearest ladders and hurried after Lannes.

There was a brief pause before the colonel of the nearest battalion turned to his astonished men and bellowed, ‘What are you waiting for? I’ll be damned if I let a marshal of France take a bullet that’s meant for me! Advance!’ He drew his sword and swept it towards the town. ‘Long live France!’

The cry was taken up by his men and they lurched into movement, running down to pick up the ladders and surging after Lannes and his officers. In an uneven tide of cheering soldiers the rest of Morand’s division swept forward, snatching up the remaining ladders as they went. Napoleon felt his blood quicken at the sight and he urged his horse to advance with the rest of the men. The defenders reacted swiftly to the new threat and every gun that could be brought to bear opened fire on the wave of men rushing across the open ground towards the ditch and the wall beyond. A roundshot briefly droned close overhead and Berthier instinctively ducked his head.

‘Sire, is this wise? You’ve already been wounded. I implore you to have your leg attended to.’

‘Later. All that matters now is taking Ratisbon.’

‘With respect, sire, Marshal Lannes can handle the attack.’

‘Really?’ Napoleon glanced at his chief of staff. ‘You saw the men. You saw how fickle their mood is. If their Emperor is with them, they will not lose heart.’

Berthier bowed his head wearily. ‘I am sure you are right, sire. But what if you are killed? Right here, before the men? Not only would the attack fail but it would be a blow to the morale of the whole army.’

Napoleon forced himself to smile.‘My dear Berthier, I can assure you that the bullet that will kill me has not yet been cast. Now, enough of this. We remain with our soldiers.’

‘Yes, sire,’ Berthier replied meekly and did his best to look unperturbed as they rode on.

Ahead of them, Napoleon could make out the gold-laced uniforms of Lannes and his officers, still leading the attack as they hurried forward. They reached the ditch, half running, half slithering down the near slope before they ran at the far side and scrambled up to cross the last stretch of open ground before the wall. Above them the battlements were lined with Austrian soldiers, firing and reloading their muskets as quickly as possible as the tide of blue uniforms surged towards them. On either flank of Morand’s division, the cannon in the enemy redoubts blasted case shot into the French ranks, sweeping several men away at a time in bloody tatters. Napoleon and Berthier reined in a short distance from the ditch and watched as Lannes and his officers reached the wall. They hurriedly raised the ladder and the marshal sprang on to the lowest rungs and started to climb. On either side other ladders were thrust against the wall and the men of Morand’s division streamed up, clambering over the breastworks and falling on the defenders.

Most had fired their muskets as they closed on the wall, and now went in with the cold steel of the bayonet, or used their weapons like clubs as they fought at brutal close quarters with the Austrians. The same fate befell the defenders of the flanking redoubts as the French fought their way in through the gun embrasures and fell on the enemy gunners within. After the death wreaked by their cannon, Napoleon knew that none of the artillery crews would be spared the vengeful wrath of the attackers.

As more men climbed over the walls there was a cheer from those still outside the town as the gates began to open. For an instant Napoleon tensed, wondering if the enemy were about to launch a counter-attack, but as the gates swung back a hatless figure in an elaborate gold-laced uniform emerged from within the town.
