One man, M. Clement, an officer of Engineers, played a prominent part in this historical affair. Soon after midday, proceeding cautiously in advance of a party of his men, who were lying in concealment between the nearest parallel and the Porte de St. Cloud, he crept up to the bastion and found it and the ramparts adjoining without a single sentinel. Keeping near the ground, he waved a white handkerchief; it was seen by the small party of Engineers who were lying outside the last parallel, and also by Lieutenant Treves, of the French Navy. At first the signal was not understood; but M. Clement continued to wave the handkerchief violently, and beckon to those who saw him to come on immediately. It was with difficulty 100 men could be collected in the trenches, but about that number advanced and occupied the deserted position. In the meantime the word was passed from post to post in their rear, and a batallion was soon on its way after them. By half-past 3 o'clock dispositions had been effected for occupying both Auteuil and the Point du Jour with a sufficient force, and proceeding to the other gates both right and left. The gates and drawbridge of Auteuil had been demolished several days previously, but the Insurgents had substituted an enormous barricade, which shut off the iron bridge uniting the Railway Station with the Viaduct. The Division of General Vergee marched direct upon Auteuil. Scarcely had the first column arrived there, when volleys of musketry were opened by the Insurgents concealed in houses. A few of the troops were put _hors de combat_ by this fire, but the artillery of the Division turned their pieces on the ramparts against the enemy, Mitrailleuses were also brought into requisition by the troops, and within an hour the Insurgents had fled to a distance. The Division of General Douai entered by the gate of St. Cloud, which is at the Point du Jour, and occupied the salient between the ramparts and the viaduct. Here there was a second bastion of considerable solidity. The soldiers entered the half-ruined barracks and casemates, and made prisoners of a number of Insurgents whom they found concealed there. Immediate preparations were then made for the advance right and left, but as the enemy was still keeping up a fire from 7-pounders and Mitrailleuses, along the bastions between Vaugirard and Montrouge, a regular assault of these positions by the division under General Cissey was determined upon. I have already announced that it has been successful. The Division began to march in by the Gates of Vaugirard and Montrouge. At 2 o'clock this morning La Muette was occupied without serious resistance. A Division subsequently advanced to Passy to join that which had taken La Muette.
