Two cannon shots, and a rattling crash of small arms, told us that the combat had begun; and as we rose the hill, the bridge of Landshut was seen on fire in three places. Either from some mistake of his orders, or not daring to assume a responsibility for what was beyond the strict line of duty, the French commander of the artillery placed his guns in position along the river's bank, and prepared to reply to the fire now opening from the town, instead of at once dashing onward within the gates. Moulon hastened to repair the error; but by the delay in pushing through the dense masses of horse, foot, and artillery that crowded the passage, it was full twenty minutes ere he came up. With a storm of oaths on the stupidity of the artillery colonel, he ordered the firing to cease, commanding both the cavalry and the train wagons to move right and left, and give place for a grenadier battalion, who were coming briskly on with their muskets at the sling. The scene was now a madly-exciting one. The chevaux-de-frize at one end of the bridge was blazing; but beyond it on the bridge the Austrian engineer and his men were scattering combustible material, and with hempen torches touching the new-pitched timbers. An incessant roll of musketry issued from the houses on the river side, with now and then the deeper boom of a large gun, while the roar of voices, and the crashing noise of artillery passing through the streets, swelled into a fearful chorus. The French sappers quickly removed the burning chevaux-de-frize, and hurled the flaming timbers into the stream; and scarcely was this done, when Moulon, dismounting, advanced, cheering, at the head of his grenadiers. Charging over the burning bridge, they rushed forward; but their way was arrested by the strong timbers of a massive portcullis, which closed the passage. This had been concealed from our view by the smoke and flame; and now, as the press of men from behind grew each instant more powerful, a scene of terrible suffering ensued. The enemy, too, poured down a deadly discharge, and grape-shot tore through us at pistol range. The onward rush of the columns to the rear defied retreat, and in the mad confusion, all orders and commands were unheard or unheeded. Not knowing what delayed our advance, I was busily engaged in suppressing a fire at one of the middle buttresses, when, mounting the parapet, I saw the cause of our halt. I happened to have caught up one of the pitched torches at the instant, and the thought at once struck me how to employ it. To reach the portcullis, no other road lay open than the parapet itself--a wooden railing, wide enough for a footing, but exposed to the whole fire of the houses. There was little time for the choice of alternatives, even had our fate offered any, so I dashed on, and, as the balls whizzed and whistled around me, reached the front.
