‘Very well, then. Where do you suggest?’

‘I’ve considered a few possibilities already, sire, having questioned the local people.’ Bertrand delved into his saddlebag and unrolled a map. He pointed a gloved finger at the map where it indicated the banks of the river, downstream from Vienna. ‘I think this looks promising, sire. Here, opposite the island of Lobau. It’s over eight hundred yards from our bank to the island, but from there to the far bank it’s only another hundred yards. And the width of the river means that the current is slower there than elsewhere as well.’

Napoleon nodded approvingly. ‘Good. Assuming this site is suitable you are to begin work the moment the bridging train reaches the army. The wagons carrying the pontoons are to have priority over all other vehicles on the road. Issue orders for that in my name.’

‘Yes, sire.’

‘I want the river bridged as quickly as possible. Understand? There’s no time to waste. The army must be across the Danube in less than a week if we are to defeat Archduke Charles.’

Bertrand puffed his cheeks. ‘As you order, sire.’

Smiling coldly Napoleon turned his attention back to the enemy troops on the far bank. The latest reports from Davout indicated that Archduke Charles and his army were still some distance from Vienna, on the far bank. If Bertrand could bridge the Danube quickly the Austrians would be caught between Napoleon and Davout and be forced to give battle. The odds would be in Napoleon’s favour, as further reinforcements under Marshal Bernadotte were marching from Dresden to join him. Provided the French army kept up its momentum Archduke Charles should be defeated before his brother arrived to help him.

Five days after the fall of Vienna, the wagons carrying the pontoons arrived and Bertrand began work on the bridge. Napoleon joined his senior engineer to watch the progress as each raft was manhandled down into the river and rowed out into the current with long oars, until it was in position to drop a heavy anchor upstream. The engineers paid off the cable until the pontoon was in line with those already secured in place; then the pontoon was linked with lengths of timber and covered in decking. A covering force of infantry had been landed on the island and they quickly flushed out the handful of Austrian defenders. General Bertrand drove his men hard and the Danube was bridged in little over a day and a half. The moment the task was complete, the first of the cavalry units began to cross.

‘Fine work!’ Napoleon congratulated the general when he reported the news to the Emperor in person, just after midday. The forward headquarters had been established in a small village close to the end of the bridge, and the countryside around was crowded with men, horses, cannon and their limbers and wagons, as the army massed ready to cross.

‘Thank you, sire.’ Bertrand bowed his head. He had not slept for nearly three days and his exhaustion was evident.

‘What of the last stage?’ Berthier asked. ‘The crossing from Lobau island to the far bank?’

‘The pontoons will cross to the island this afternoon, and we’ll bridge the final gap tonight.’

‘Excellent.’ Napoleon smiled warmly. ‘Then by dawn we’ll have our bridgehead. Massйna’s corps will take the villages of Essling and Aspern and then the rest of the army can cross.’

Marshal Lannes leaned forward in his chair and cleared his throat. ‘That’s all very well, sire, but can we be sure that the enemy will not contest our landing on the far bank?’

‘Rest assured, my dear Lannes, the Austrian army is still many days’ march away. The first they’ll know about our crossing the Danube is when the cannon announce our presence. By then, it will be too late to do anything but give battle.’

‘But if the Austrians are closer than you have calculated, then we could be advancing into a trap of our own making. Sire, I urge caution. We are advancing over a fast-flowing river on a single bridge. What if this span broke, or was destroyed? Then the army would be cut in half. The vanguard would be at the mercy of the enemy if they could gather sufficient forces to oppose us. Sire, it is too much of a risk.’

‘The enemy are not strong enough to hamper the river crossing, I assure you. War is the realm of risk, chance and opportunity. In this case it is my judgement that the opportunity outweighs the risk.’ Napoleon’s tone hardened.‘Gentlemen, the orders are given and the army begins to cross the Danube tonight.’

THE IBERIAN PENINSULA

Chapter 3

Arthur

Abrantes, Portugal, June 1809

General Sir Arthur Wellesley lowered the letter with a frustrated sigh and leaned back in his chair. Even though he sat in the shade outside the small tavern the noon heat was stifling. Not so bad as India, he recalled, but beyond reasonable comfort all the same. He had taken off his coat and sat bareheaded at a plain trestle table as he dealt with the morning’s reports and correspondence. The army had halted at the Portuguese town of Abrantes several days earlier as it waited for supplies and money. The latter was Arthur’s most pressing concern. Not only had his men not been paid for over two months, but there were also numerous bills that required settling with Portuguese grain merchants and horse dealers, as well as the need for twenty thousand pairs of boots to replace those worn out by his men. It was Arthur’s policy that the British army must pay its way in the Peninsula if it was to enjoy the continued support of the Portuguese and Spanish people. His army was outnumbered at least five to one as things stood and the British could not afford the enmity of the people across whose land they campaigned.

Arthur knew that the French took a less enlightened view regarding their supplies, and lived off the land with no regard for the consequent attitude of the local people. As a result the French had incurred the wrath of the Spanish and Portuguese peasants who now waged a pitiless war of resistance, ambushing French patrols, harassing their columns and butchering any stragglers left behind.

Arthur looked down the steep slope towards the river Tagus. The water flowed with a serene grace through hills planted with groves of olive and fruit trees and the men of the British army were enjoying a hard-earned rest as they waited for their commander to decide on his next steps. Hundreds of soldiers were lining the bank, taking the chance to wash their clothes, while the more adventurous had stripped and were splashing in the shallows.

Arthur permitted himself a small smile as he regarded them. The men had performed well at Oporto a month earlier, where they had surprised Marshal Soult and sent him fleeing towards Spain, abandoning all his artillery and wagons in the process. Besides proving that they could march hard, the redcoats had shown that they could stand up to the fanatical attacks of the French at the earlier battle of Vimeiro. Arthur was confident that his army, even outnumbered as it was, had the beating of all the marshals and men of Napoleon’s forces in the Peninsula, provided that the French were prevented from concentrating their armies. That was the trick of it, Arthur reflected. He must defeat them in detail until the Peninsula was liberated. Conversely, he dare not let his army suffer a single setback.

He commanded the largest British army in the field and there were many at home in England who loudly questioned the sagacity of supporting such a large force in the Peninsula, far from the vital battlefields of central Europe, where Arthur’s men could be better used. He disagreed. It was best to deploy valuable British soldiers where they stood a good chance of tipping the scales. Even so, Arthur’s political masters had proved reluctant to allow him to take risks. Or they had been until the victory at Oporto. Then, true to form, the politicians had veered from caution to opportunism in an instant.
