Worth came up almost immediately; and, directing the Sixth to advance as best they could along the causeway in the teeth of the _tête de pont_, despatched Garland and Clarke’s brigades through the fields on the right to attack it in flank. Every gun was instantly directed against the assailants; and, though the day was bright and clear, the clouds of smoke actually darkened the air. Hoffman, waving his sword, cheered on the Sixth; but the shot tore and ripped up their ranks to such a degree that in a few minutes they had lost ninety-seven men. The brigades on the right suffered as severely. One hundred men fell within the space of an acre. Still they pressed on, till the Eighth (of Clarke’s brigade) reached the ditch. In they plunged, Lieutenant Longstreet bearing the colors in advance--scrambled out on the other side--dashed at the walls, without ladders or scaling implements--bayoneted the defenders as they took aim. At last officers and men, mixed pell-mell, some through the embrasures, some over the walls, rushed or leaped in and drove the garrison helter-skelter upon their reserves. The _tête de pont_ gained, its guns were turned on the convent, whence the Mexicans were still slaughtering our gallant Second and Third. Duncan’s battery, too, hitherto in reserve, was brought up, and opened with such rapidity that a bystander estimated the intervals between the reports at three seconds. Stunned by this novel attack, the garrison of San Pablo slackened fire. In an instant the Third, followed by Dimmick’s artillery, dashed forward with the bayonet to storm the nearest bastion. With a run they carried it, the artillery bursting over the curtain; but at that moment a dozen white flags waved in their faces. The whole fortified position of Churubusco was taken.
