Our conversation was now lost in the roar of artillery, and after a tremendous fire of an hour on the French position, which was answered with equal weight from the heights, a powerful division was sent to assail the principal battery. The attempt was gallantly made, and the success seemed infallible, when I heard, through all the roar, the exclamation of Macdonald, "Brave Steingell!" At the words, he pointed to a heavy column of infantry hurrying down the ravine in rear of the redoubt. "Those are from the camp," he exclaimed, "and a few thousands more will make the post impregnable." The sight of the column seemed to have given renewed vigour to both sides; for, while the French guns rapidly increased their fire, aided by the musketry of the newly arrived troops, the Prussian artillerists, then the first in Europe, threw in their balls in such showers, that the forest, which hitherto had largely screened the enemy, began to fall in masses; branch and trunk were swept away, and the ground became as naked of cover as if it had been stripped by the axe. The troops thus exposed could not withstand this "iron hail," and they were palpably staggered. The retreat of a brigade, after suffering immense loss, shook the whole line, and produced a charge of our dragoons up the hill. I gave an involuntary glance at Macdonald. He was pale and exhausted; but in another moment his eye sparkled, his colour came, and I heard him exclaim, "Bravo, Chazot! All is not lost yet." I saw a group of mounted officers galloping into the very spot which had been abandoned by the brigade, and followed by the colours of three or four battalions, which were planted directly under our fire. "There comes Chazot with his division!" cried the aide-de-camp; "gallant fellow, let him now make up for his ill fortune! Monsieur Brunswick will not sleep on the hill of Valmy to-night. He has been unable to force the centre, and now both flanks are secured: another attack would cost him ten thousand men. Nor will Monsieur Brunswick sleep on the hills of Valmy to-morrow. Dumourier was right; there was his Thermopylae. But it will not be stormed. _Vive la France!_" The prediction was nearly true. The unexpected reinforcements, and the approach of night, determined the generalissimo to abandon the assault for the time. The fire soon slackened, the troops were withdrawn, and, after a heavy loss on both sides, both slept upon the field.
