‘That comes from the direction of Davout’s corps.’ Napoleon frowned. ‘What the devil is he up to? The orders were for the attack to begin at four. This is the work of some glory-hunter with an itchy trigger finger. Well, whoever it is, he’ll have to answer to me when the day is over.’ He turned abruptly to Berthier. ‘No point in waiting for four now. Send orders to all corps to begin the attack at once.’

‘Yes, sire.’

The distant cannon fire quickly swelled into a continuous rumble as the skirmish line began to filter forward towards the enemy. Then, with a deafening crash, the guns of Masséna’s corps opened fire on the Austrian centre, pounding the village of Aderklaa, a short distance from Wagram in the blue-hued light of the predawn. As the bombardment continued, Napoleon watched the officers of the leading infantry columns ride up and down their ranks, shouting encouragement to the men.

Berthier appeared at his side with a nervous expression.

‘What is it?’

‘Sire, a message from Davout. He is under attack.’

‘Under attack?’

‘Yes, sire. The enemy have fallen on his right flank. He is being driven back.’

‘No, Davout must be mistaken. It’s probably just a local counter-attack. Nothing more.’

‘His messenger says the Austrians are attacking in force, sire.’

‘Rubbish!’

Before Napoleon could give further vent to his anger, he was aware of a sudden increase in the sound of gunfire to his right. He turned to stare towards the flank, unable to comprehend the obvious at first. Then he smiled ruefully. ‘Who would have guessed it? Archduke Charles has finally learned to take the initiative.’ He turned to Berthier. ‘The enemy have got their attack in before us.’

‘Tell all corps commanders to hold their positions, until I discover exactly what is going on.’ Napoleon listened again to the cannonade to his right and made another decision. ‘We must be ready to reinforce Davout. Send the cavalry reserve and all the horse artillery to cover the end of our right flank.’

‘Yes, sire. Do you wish me to order Masséna to suspend his bombardment?’

‘No. It may help to unsettle the enemy. Let him continue.’ Napoleon scratched his chin anxiously for a moment. The situation between the two armies had changed completely. Instead of launching a decisive attack to break the Austrians, the Grand Army was itself under attack. He dared not proceed with his original plan until he had discerned the intentions of Archduke Charles.‘I’m riding over to Davout. I have to see what is happening for myself. The rest of the army is to hold its ground and be ready to receive new orders. One other thing: have the Imperial Guard moved two miles to our right, in case I need to call on them in a hurry.’
