We have been in a state of wild enthusiasm all this afternoon. At about 1 o'clock it was rumoured that 20,000 Prussians and 40 cannon had been taken. There had been a heavy firing, it was said, this morning, and a Prussian force had approached near the forts of Ivry and Bicetre. General Vinoy had issued forth from Vincennes, and, getting behind them, had forced them under the guns of the forts, where they were taken prisoners. The Boulevards immediately were crowded; here a person announcing that he had a despatch from the front, here another vowing he had been there himself. Wherever a drum was heard there was a cry of "Here come the prisoners!" Tired of this, at about 4 o'clock I drove to Montrouge. It is a sort of Parisian Southwark. I found all the inhabitants lining the streets, waiting, too, for news. A regiment marched in, and there was a cry that it had come from the front; then artillery filed by out of the city gate. I tried myself to pass, and had got half-way through before I was stopped, then I was turned back. The prisoners here, close by the scene of action, had dwindled down to 5,000. Imagine Southwark, with every man armed in it, and a battle going on at Greenwich, and you will have an idea of the excitement of Montrouge. 6 _o'clock_ P.M. The Boulevards almost impassable; the streets before the Mairies absolutely impassable; no official confirmation of the victory. Everyone who is not inventing news is waiting for it. A proclamation has been issued by General Trochu conceived in a very sensible spirit, telling the National Guard that the moment is ill chosen for pacific demonstrations, with crowns and bouquets. I hear that some of the soldiers who ran away at Clamart have been shot.
