The major frowned, then his head slumped and his legs buckled as he fell on to the bridge. Napoleon paused and reached down to help his companion. As he did so one of his men thrust past, desperate to escape the slaughter. He was a large man and he sent his general reeling towards the edge of the bridge. The rail had been splintered by grapeshot and gave way with a crack the moment Napoleon fell against it. He flung his arms forward, dropping the standard as he desperately tried to keep his balance, but his momentum was too great and he tumbled backwards off the bridge. He landed on his back in the mud, the impact driving the breath from his body. For a second he was staring up at the clear sky, dazed.Then he rolled over and tried to push himself up, but the mud sucked his hands down. With great difficulty Napoleon scrambled upright and tried to take a step, but his boots just churned up the filthy mire and he sank up to his knees, far enough to hold him in place.

‘General!’ a voice cried from above and Napoleon looked up at the bridge.

‘Sir? Where are you?’ Marmont cried out.

‘Here! Down here!’

A moment later Marmont’s head appeared over the rail.

‘Get me out!’ Napoleon shouted.

Marmont nodded and his head disappeared from view. A moment later he leaped over the rail a short distance further along, closer to the bank, and landed in the reeds. Louis jumped after him and they thrust their way through the rasping stalks until they emerged at the edge of the mud. Napoleon leaned towards them, stretching out his arms.

‘Shit! I can’t reach.’

Marmont turned to Louis. ‘Hold my legs!’

Then he fell forward on to the mud and grabbed at his general’s hands. As soon as he had a good hold he grunted over his shoulder, ‘Pull us back.’

Louis wrapped his arms round one of Marmont’s boots, and, digging his heels into the soft ground at the base of the reeds, he pulled with all his might. At first Napoleon did not feel himself budging, and then with a glutinous sucking he lurched towards Marmont.

‘Keep pulling!’ Marmont called back to Louis. ‘He’s coming!’

Napoleon kept as flat as he could to spread his weight, and slowly they drew him out of the mud. Just then there was a shout from the Austrian bank and glancing back Napoleon saw a handful of men pointing at them from behind a wall. One of the men levelled his musket and fired.There was a dull plop close by Napoleon’s side and a plug of dark mud leaped into the air, leaving a furrow in the glistening brown surface. Marmont was back on solid ground now and wrenched Napoleon after him. He emerged from the mud, plastered in filth, as more shots slapped into the mud around them.
