In the longest campaign in European history, in less than two years the Russian army had marched from Vilna to Moscow and then all the way back across Europe to Paris. With the enemy capital in sight at last, speed was now essential. Paris must be taken before Napoleon arrived to galvanize and reinforce its defence. The Bavarians and Sacken’s Army Corps had been left at Meaux to guard the allied rear in case Napoleon attempted to march on Paris by the most direct route. But that night orders went out to all other corps for a full-scale assault on Paris on the very next day, 30 March. On the allied right, the Army of Silesia was to attack the capital from the north, heading for Montmartre and La Chapelle. On the left the Württemberg corps was to advance from the east along the north bank of the Seine, past the chateau of Vincennes. General Gyulai’s Austrians would support the Württembergers. Peter Wittgenstein had returned to Russia, handing over command of his Army Corps to Nikolai Raevsky. He would lead the attack in the centre towards Romainville and Pantin. In all, the attacking force added up to 100,000 men. Behind Raevsky, to be used if necessary, stood the Grand Duke Constantine’s Reserve Army Corps, made up of the Guards and Grenadiers.33
The position held by the French was very strong. The heights of Montmartre to the north and of Romainville in the centre were major obstacles for an attacking army, around which the capital’s defence could be anchored. As one would expect on the outskirts of one of Europe’s greatest cities, the whole area was also a maze of stone buildings and walls. Napoleon, however, had done nothing to strengthen the city’s natural defences. Moreover, there were only 38,000 men to hold a long defence line, and of these many thousands were National Guardsmen with minimal training and unreliable muskets. Under the overall authority of Napoleon’s brother Joseph, Marshal Mortier was responsible for defending the northern sector against the Army of Silesia and Marshal Marmont the eastern sector against the allied main army. All three men knew that unless the defenders were willing to fight in the streets of Paris and bury themselves under the city’s rubble, their chances of success were slight. If the whole allied assault force had attacked simultaneously early in the morning of 30 March, the city would probably have fallen by lunchtime.
In fact, allied plans went awry. It was clear even on the evening of 30 March that the Württembergers and Austrians were still so far in the rear that they could not launch their attack until early the following afternoon. Meanwhile the aide-de-camp carrying Schwarzenberg’s orders to Blücher got lost in the dark, which meant that most of the Army of Silesia would only be ready to attack at eleven o’clock, six hours later than planned. As a result, the initial allied assault was only made by the 16,000 men of Raevsky’s Army Corps in the allied centre. Fortunately for the Russians they found the key village of Romainville undefended and were able to seize it before Marmont had time to send troops to occupy it. They also took the village of Pantin early in the morning. But it was all they could do to hold these strongholds against French counter-attacks in the morning of 30 March.
All attempts to break forward out of the villages came to nothing. The Prussian Guards infantry, not in action since the spring of 1813, stormed forward out of Pantin with great courage but was stopped in its tracks with heavy casualties. Amidst the buildings, walls and gardens all formation was lost and the battle dissolved into confused skirmishing and fire-fights. Barclay de Tolly moved up the two Russian Grenadier divisions in Raevsky’s support and came up to the front line himself to coordinate operations. Very sensibly, he got most of the regiments back into battalion columns ready for a new push, but ordered Raevsky not to mount a major new attack until the Württembergers were in position on his left and the Army of Silesia was absorbing Mortier’s full attention on his right.34
