Since Britain had no troops in the allied army, Lord Burghersh – its military representative at headquarters – was a relatively impartial observer. He called the Russian performance at Craonne ‘the best fought action during the campaign’. Vorontsov, Vasilchikov and their troops had certainly shown great skill, discipline and courage. The performance of Vorontsov’s infantry was particularly striking because few of his regiments had seen serious combat since the spring of 1813 and for many of his men this was their first experience of battle. The French subsequently claimed victory because Blücher’s plan had failed and because they held the battlefield at the end of the day. In this narrow sense they were indeed victorious, just as they had been ‘victorious’ in these terms in every Russian rearguard action during their advance to Moscow in 1812. But the Russians left behind no guns and very few prisoners. Clausewitz sums up the battle of Craonne by saying that ‘the Russians defended themselves at Craonne so successfully that the main goal, to reach Laon undisturbed, was achieved…this was accomplished by exceptionally brave soldiers, a very self-possessed commander and an excellent position’.12
The Russians lost 5,000 men. The earliest full French account puts their own casualties at 8,000 and since they were very disinclined indeed to overstate their losses this figure may be accurate. Subsequently, however, French historians chipped away at the numbers and Henri Houssaye wrote that ‘the Russians lost 5,000, the French 5,400’. A contemporary French expert tweaked the figures still further, claiming that the allies lost 5,500 men and Napoleon only 5,000. Presumably this was in order to stake an additional claim to victory. In the same spirit 29,000 Frenchmen are said to have faced 50,000 allies, which may be true if one counts every soldier within a day’s march of the battle but completely distorts what actually happened on the battlefield on 7 March. In reality all of this juggling of statistics is irrelevant, though it does help to illustrate the historian’s difficulties in getting at the truth. Even if in fact the Russians and the French had lost the same number of men at Craonne, the basic point was that Napoleon could no longer afford this kind of attrition.13
Napoleon followed up Blücher to Laon and on 9 March attacked the Russo-Prussian forces there. Once again he believed that he was likely to face only a rearguard and drastically underestimated the size of the allied army. In fact Blücher had concentrated all his corps near Laon, almost 100,000 men, and outnumbered the French by more than two to one. In addition, Napoleon’s army was divided in two, with the emperor advancing up the road from Soissons and Marmont up the road from Rheims. Communication between the two wings was very difficult because of the Russian light cavalry and the swampy terrain. Not at all surprisingly, Napoleon’s attack on 9 March failed. After darkness set in that evening the Prussians themselves surprised and routed Marmont in one of the most successful night attacks of the war. Napoleon’s army was now at the allies’ mercy. He was saved by Blücher’s breakdown, which paralysed the Army of Silesia. The immense strains of the previous two months had ruined the health of the 72-year-old field-marshal. After Prussia’s defeat in 1806–7 Blücher had suffered a breakdown, a side effect of which was alarming hallucinations about giving birth to an elephant. Now staff officers who came to him for orders found him in another world and unable to respond to their enquiries. Any light on his eyes caused him great suffering.14
The next few days revealed the fragility of the coalition armies’ command structure and just how much the Army of Silesia had depended on Blücher’s drive, courage and charisma. In principle the army’s senior full general was Alexandre de Langeron but there was no chance of Yorck or Bülow obeying him. Langeron himself dreaded the idea of having to take over command and argued that Gneisenau should do so, as Blücher’s chief of staff and the man best informed of the commander-in-chief’s intentions. Neither Yorck nor Bülow much respected Gneisenau, however, and in addition he was junior to both of them. Yorck chose this moment to act the prima donna and resign his command, only returning to duty after Blücher scrawled an appeal to him which was supported by the pleas of Prince William of Prussia, one of Yorck’s brigade commanders and the king’s brother. Deprived of Blücher’s strength and inspiration, Gneisenau lost confidence and courage. He fell prey to one of his congenital failings, the belief that Prussia was being betrayed by her allies. The result was that for more than a week after the battle of Laon the Army of Silesia spread out in search of food but played no useful role in the war.15
