The sortie was planned to take place on January 19th. On that day, as we have seen, General Faidherbe advanced as far as St. Quentin on the way to Paris, and the army which was to make the sortie stood on the eastern and northern fronts of the capital. The attempt to break through was, however, made in the opposite direction. But in fact, the peninsula of Gennevilliers was now the only ground on which large masses of troops could still be deployed without being exposed for hours while they were being assembled, to the fire of the German artillery. Two days previously the mobilized National Guards had already relieved the three Divisions of the sortie-Army from the positions they had held; and those Divisions, collectively 90,000 strong, were to move to the attack in three columns simultaneously. General Vinoy on the left, supported by the fire from the enceinte, was to carry the height of Montretout; General Bellemare in the centre was to push forward through Garches; General Ducrot on the right by way of the Chateau of Buzanval. The attack was set to begin at six in the morning, but blocks occurred at the bridges of Asnieres and Neuilly, as no specific orders had been issued for regulating the crossing. When at seven o'clock the signal to advance was made from Mont Valerien, only the advance of General Vinoy's force was ready, the other columns had not yet deployed, and the last detachments tailed back as far as Courbevoix. Before they had reached their rendezvous-points the left wing was already marching on St. Cloud with fifteen battalions. These at first met only isolated posts and patrols, eighty-nine men in all, who rushed into the open gorge of the redoubt of Montretout, and there made a stand for some time; they then fought their way out with great bravery, but some of them were taken prisoners. There, and in the northern part of St. Cloud, the French promptly prepared for defence. The centre column under General Bellemare also took possession without difficulty of the height of Maison du Cure. Not till now, at nearly nine o'clock, did the first supports of the German forepost line appear on the scene. Till within a short time the observatories had been able to report nothing but "thick fog;" but reports from the right and left wings announced that a serious attack was threatened on the whole front from St. Cloud to Bougival. The Vth Corps was now alarmed, and General von Kirchbach betook himself to the 9th Division. On the German right, in the park of St. Cloud, stood the 17th Brigade; on the left, behind the Porte de Longboyau, the 20th; the other troops of the Corps marched from their quarters in Versailles and the villages to its north, to Jardy and Beauregard. The Crown Prince ordered six battalions of the Guard Landwehr and a Bavarian Brigade to Versailles, and himself rode to the Hospice of Brezin; the King went to Marly.
