A great explosion, followed by a conflagration, occurred at half-past 12 at the Staff Quarters near the Esplanade of the Invalides.

Paris is now completely surrounded.

It is asserted that Dombrowski is hemmed in at Ouen.

The Insurgents have established a battery upon the terrace of the Garden of the Tuileries, the fire of which sweeps over the Champs Elysées; but this position has been turned by General Clinchamp, and there is reason to hope that the resistance will not be of long duration.

The Versailles troops have already captured from 8,000 to 10,000 prisoners.

Fighting has been going on all this morning, the cannonade and musketry fire being incessant.

There is a large fire in the neighbourhood of the St. Lazare Railway Station, and a dense cloud of smoke hangs over the heights of Montmartre. Not only have the Germans completely isolated Paris, but all communication between Versailles and St. Denis is also cut off. Trains arriving from the North no longer enter Paris, but stop at St. Denis.

It is rumoured that the Prussians occupy Fort Vincennes.

The strictest orders have been given to the German outposts to drive back all Insurgents, and the advanced corps have been doubled tonight to prevent any from breaking through the circle of investment north of Paris.

A wounded Insurgent General attempted to pass the Prussian outposts, but was forced to retrace his steps.
