Napoleon walked with them a short distance, until he reached the small rise that gave out on to the open ground. Then he stopped to watch the attack, all the while conscious of the column held up on the track behind him. Even now, a messenger would be riding towards the Austrian commander to alert him to the force that had appeared behind the rearguard. When the column was halfway across the open ground Lannes ordered them to break into a run and with the grenadier company in the lead the men streamed towards the narrow span crossing the river.There was a blasting thud from the far side of the river as a plume of fire and smoke erupted from the muzzle of one of the enemy cannon. An instant later the grapeshot tore through the men at the head of the charge, cutting several down. Lannes was untouched and waved his sword above his head, calling out to his men to follow him as he covered the remaining distance to the bridge. There was no semblance of formation now as his men sprinted forward, heads instinctively lowered. As soon as they pounded on to the first stretch of the bridge the far bank erupted in a cloud of smoke as the infantry fired. More men fell, one tumbling over the low timber rail and out of sight into the reeds below. As Napoleon watched a ball plucked off Lannes’s hat, yet the colonel did not flinch as he turned briefly to beckon his men on, then charged forward again. They reached the centre of the bridge before the second cannon fired, the grapeshot carving a bloody lane through the blue ranks pressing on. The grenadiers edged forward, the front ranks crouching low, holding up those behind them, and all the time musket fire whittled down their numbers. The charge ground to a halt as those at the front fired back and then made to reload.
