Philipp Stadion reached allied headquarters at nine in the morning on 13 May, eleven days after the battle of Lutzen and one week before the battle of Bautzen. He met Nesselrode twice that day. In a report to Alexander written on 13 May Nesselrode summarized the Austrian position as explained by Stadion. Vienna would insist on the restoration of the territories lost by it in 1805 and 1809. It would support whatever restoration of Prussian territory was stipulated in the Russo-Prussian treaty of alliance. It would demand the extinction of the Duchy of Warsaw, of all French territory east of the Rhine, and of the Confederation of the Rhine itself. If Napoleon did not accept these conditions by 1 June Austria would enter the war, regardless of what had happened on the battlefield between then and now. Stadion would agree with the allies the principles of a plan for joint military operations. Nesselrode commented correctly that ‘without doubt the conditions set out will never be accepted by France’. He added that ‘Count Stadion promises formally in the name of his court that no evasive or dilatory response by Napoleon will hold her back beyond the end of this period from executing the plan of operations which will have been agreed between her and the allied courts’.59
Nesselrode was a very calm and experienced diplomat. It is inconceivable that he misinterpreted Stadion, deliberately or otherwise, on so crucial a matter. Stadion himself was a former Austrian foreign minister. For all his hatred for Napoleon and the French Empire in Germany, he would never deliberately have misled the Russians. To do so would have been hugely risky both in military terms and in its impact on Austro-Russian relations. Perhaps Stadion allowed his enthusiasm too free a rein in interpreting his instructions, though it is impossible to know what was said between him and Metternich before his departure to allied headquarters. Whoever was to blame, however, there is no doubt that what Stadion told Nesselrode did not represent the true state of affairs in Vienna.
In the first place it was by no means certain that Francis II would take the uncompromising line suggested by Stadion in the event of Napoleon rejecting any of the Austrian minimal conditions, seeking delay, or winning victories over the allies on the battlefield. In addition, when Nesselrode three weeks later finally got to meet Field-Marshal Schwarzenberg and General Radetsky, the two key officers of the Army of Bohemia, they assured him that it had never been conceivable for the Austrian army to cross the Bohemian frontier before 20 June. Russian bafflement and suspicion was inevitable. Did Stadion speak for Metternich? What were the slippery foreign minister’s true views and did he speak for Francis II? Did any Austrian statesman understand, let alone control, what the army was doing to prepare for war?60
Categorical Austrian assurances of support were a powerful additional reason for the allies to risk another battle against Napoleon by stopping their retreat at Bautzen. Nevertheless, though there were excellent reasons for trying to gain time and delay Napoleon, the decision was a very risky one. At the battle of Bautzen on 20–21 May the allies could muster only 96,000 men: Napoleon had double that number present by the end of the battle and his superiority was even greater as regards infantry, which would be the decisive arm on the battlefield. On the map the terrain at Bautzen seemed to favour a stout defence. When they arrived on the scene, as was their habit, the Russian troops immediately began to dig entrenchments and fortifications. Although individual strong points were formidable, however, the position was divided up into a number of sectors by streams and ravines. It would be very difficult to coordinate the defence or move reserves from one sector to another. Above all, the allied position was too extended for such a relatively small force. The Russians had four times fewer men per kilometre than had been the case at Borodino.
