Late that evening, the 20th, we resumed our old quarters at Lagny, and early next day I made a visit to the royal headquarters at Ferrires, where I observed great rejoicing going on, the occasion for it being an important victory gained near Mendon, a French corps of about 30,000 men under General Ducrot having been beaten by the Fifth Prussian and Second Bavarian corps. Ducrot had been stubbornly holding ground near Mendon for two or three days, much to the embarrassment of the Germans too, since he kept them from closing a gap in their line to the southwest of Paris; but in the recent fight he had been driven from the field with such heavy loss as to render impossible his maintaining the gap longer. The Crown Prince of Prussia was thus enabled to extend his left, without danger, as far as Bougival, north of Versailles, and eventually met the right of the Crown Prince of Saxony, already at Denil, north of St. Denis. The unbroken circle of investment around Paris being well-nigh assured, news of its complete accomplishment was momentarily expected; therefore everybody was jubilant on account of the breaking up of Ducrot, but more particularly because word had been received the same morning that a correspondence had begun between Bazaine and Prince Frederick Charles, looking to the capitulation of Metz, for the surrender of that place would permit the Second Army to join in the siege of Paris.
Learning all this, and seeing that the investment was about completed, I decided to take up my quarters at Versailles, and started for that place on the 22d, halting at Noisy le Grand to take luncheon with some artillery officers, whose acquaintance we had made the day of the surrender at Sedan. During the meal I noticed two American flags flying on a couple of houses near by. Inquiring the significance of this, I was told that the flags had been put up to protect the buildings—the owners, two American citizens, having in a bad fright abandoned their property, and, instead of remaining outside, gone into Paris,—“very foolishly,” said our hospitable friends, “for here they could have obtained food in plenty, and been perfectly secure from molestation.”
