Russia Against Napoleon_ The True Story of the Campaigns of War and Peace - Dominic Lieven [305]
Castlereagh could sign a treaty with Napoleon so long as this secured Belgium and was accompanied by formidable barriers against renewed French aggression, and so long as there appeared to be no other force available in France with which to make peace. Under no circumstances, however, could he accept France’s ‘natural frontiers’. Even Austrian hints about such terms would drive Castlereagh into Alexander’s arms. By the end of February, therefore, Metternich had every reason to seek a compromise. So too, however, did the Russian emperor. His political isolation from his allies in early February, coupled with Napoleon’s military victories, showed the dangers of intransigence. As a result, on 1 March 1814 the four allied great powers signed the Treaty of Chaumont, pledging themselves only to accept a peace based on France’s historic borders, an independent and extended Netherlands, and a German confederation of sovereign states dominated by Austria and Prussia. At least as important, the treaty was also a military alliance between the four powers, designed to last for twenty years after the peace was signed and to uphold this peace by joint military action if France attempted to breach its terms. The Treaty of Chaumont could not determine whether the allies would make peace with Napoleon or some alternative French regime. All the allied leaders knew that to a great extent this would have to depend on the French themselves. Nevertheless the treaty was in both real and moral terms a big boost to allied unity.7
Ultimately, however, it was military operations that were most likely to determine Napoleon’s fate. Only total defeat could persuade him to accept, even temporarily, the 1792 frontiers. Equally, the emperor’s defeat was the likeliest catalyst for a revolt of the French elites against his rule. In the second half of February defeat once again seemed far away. Schwarzenberg’s army was in full retreat. Initially the plan was to summon Blücher to march south to join with the main army and offer battle but by the time the Army of Silesia arrived in the vicinity on 21 February Schwarzenberg had changed his mind. The commander-in-chief insisted on detaching most of his Austrian troops southwards to block what he considered to be a growing threat to his communications from Marshal Augereau’s army in Lyons. This gave him an excellent reason – his critics used the word ‘excuse’ – to continue his retreat southwards and avoid a battle. Blücher was outraged and Alexander seriously considered removing himself and the Russian corps from the main army and joining up with Blücher.
In the end a compromise was hammered out in a conference of the allied leaders at Bar-sur-Aube on 25 February. Schwarzenberg would continue his retreat as far as Langres if necessary, where he would be joined by the newly arriving Austrian reserves. If Napoleon was still pursuing him he would turn at Langres and fight a defensive battle. Meanwhile Blücher was to march northwards and, it was hoped, draw Napoleon off Schwarzenberg’s back by threatening Paris. If, as was expected, Napoleon turned round and pursued Blücher, Schwarzenberg was to resume the offensive. Bülow and Winzengerode’s Army Corps of Bernadotte’s former Army of the North had in the meantime marched from the frontiers of Holland towards Paris and were now approaching Soissons on the river Aisne. They would come under Blücher’s command, as would the newly formed Saxon corps of the German federal forces, whose job it would be to hold the Low Countries. Even without the Saxons, Blücher
