"The tricolour flag waves over the Buttes-Montmartre and the Northern Railway station. These decisive points were carried by the troops of Generals Ladmirault and Clinchant, who captured between 2,000 and 3,000 prisoners. General Douai has taken the Church of the Trinity, and is marching upon the Mairie in the Rue Drouot.

"Generals Cissey and Vinoy are advancing towards the Hôtel-de-Ville and the Tuileries.

may 24th.

"The Generals, desiring to treat the city with lenity, withheld any attack upon public monuments in which the insurgents had taken up positions. This morning they carried the Place de la Concorde. The Ministry of Finances, the Hôtel of the Conseil d'Etat, the Palace of the Légion of Honour, and the Palace of the Tuileries were burnt by the insurgents. When the troops gained possession of the Tuileries, it was but a mass of smouldering ashes. The Louvre will be saved. The Hôtel de Ville is in flames. I am convinced that the insurrection will be completely conquered by this evening at the latest. No one could have prevented the crime of these wicked wretches. They have made use of petroleum for their incendiary purposes, and have sent petroleum bombs against the soldiers. What remedy can be applied? The best of the Generals of the army have shown an amount of talent and valour which has excited the admiration of foreigners.

I have just returned from witnessing one of the saddest sights that has occurred in the world's history.

I announced that the insurgents had set fire to several of the public buildings of Paris, the Royal and historical Tuileries included. Flames and bombshells are fast reducing the magnificent city to a huge and shapeless ruin. Its architectural glories are rapidly passing away in smoke and flame, such as have never been witnessed since the burning of Moscow, and amid a roar of cannon, a screaming of mitrailleuses, a bursting of projectiles, and a horrid rattle of musketry from different quarters which are appalling. A more lovely day it would be impossible to imagine, a sky of unusual brightness, blue as the clearest ever seen, a sun of surpassing brilliancy even for Paris, scarcely a breath of wind to ruffle the Seine. Such of the great buildings as the spreading conflagration has not reached stand in the clearest relief as they are seen for probably the last time; but in a dozen spots, at both sides of the bridges, sheets of flame and awful volumes of smoke rise to the sky and positively obscure the light of the sun. I am making these notes on the Trocadéro. Close and immediately opposite to me is the Invalides, with its gilded dome shining brightly as ever. The wide esplanade of the École Militaire, almost immediately underneath it, is nearly covered with armed men, cannon, and horses. Shells from the positions of General Cissey, at Montrouge, are every minute falling close to the lofty dome of the Panthéon. It and the fine building of Val de Grace, near it, seem certain to be destroyed by missiles before the incendiary fire reaches them. There is a dense smoke close to St. Sulpice, and now flame rises amid the smoke, and the two towers of the church are illuminated as no electric light could illuminate them. Some large building is on fire there. Every one asks which it is; but no one can approach that Quarter to put the matter beyond doubt. Burnt leaves of books are flying towards us, and the prevailing opinion is that the Sorbonne and its Library are being consumed. There are a dozen other fires between that and the river. No one doubts that the Palais de Justice is sharing the fate of the Tuileries and the Louvres. The Château of the Tuileries has all but disappeared. The centre cupola has fallen in, and so has the roof along the entire length of the building. Some of the lower stories yet burn, for fire and smoke are rushing fiercely from the openings where up to this morning there were window-frames and windows.

The Louvre is not yet wholly gone, and perhaps the fire will not reach all its Courts. As well as we can make out through the flame and smoke rushing across the gardens of the Tuileries, the fire has reached the Palais Royal. Every one is now crying out, "The Palais Royal burns!" and we ascertain that it does. We cannot see Notre Dame or the Hôtel Dieu. It is probable that both are fast becoming ashes. Not an instant passes without an explosion. Stones and timber and iron are flying high into the air, and falling to the earth with horrible crashes. The very trees are on fire. They are crackling, and their leaves and branches are like tinder. The buildings in the Place de la Concorde reflect the flames, and every stone in them is like bright gold. Montmartre is still outside the circle of the flames; but the little wind that is blowing carries the smoke up to it, and in the clear heavens it rises black as Milton's Pandemonium. The New Opera House is as yet uninjured; but the smoke encircles it, and it will be next to a miracle if it escapes. We see clearly now that the Palais de Justice, the Ste. Chapelle, the Prefecture of Police, and the Hôtel de Ville are all blazing without a possibility existing of any portion of any one of them being saved from the general wreck and ruin.

The military are as far as the Pont Neuf on the left bank of the river, and just beyond the Hôtel de Ville on the right. Now, at 6 o'clock, it is all but certain that when this fire is extinguished scarcely one of the great monuments of Paris will have escaped entire destruction.

The barricade of the Insurgents at the end of the Rue Royale was taken last night by a movement in which the troops made their way from house to house, starting from the Rue Boissy d'Anglas, to the Rue Faubourg St. Honoré. The fighting in the Rue Faubourg St. Honoré and the Avenue Marigny was very severe. Six shells fell and exploded in the grounds of the British Embassy. The two houses which formed the angles at the corners of the Rue Royale and the Rue Faubourg St. Honoré were burnt to the ground. The Place Vendôme was taken by the troops. In the Faubourg St. Germain during the whole night an energetic combat was raging between the Insurgents and the men of General Cissey's division.

The Versailles batteries are firing furiously against the Quarters which still hold out. By the aid of the telescope the horrible fact is disclosed of numerous dead and wounded left lying about the streets without any succour whatever.
