Cavalry Crossing a Ford - by Walt Whitman

A LINE in long array, where they wind betwixt green islands;
They take a serpentine course—their arms flash in the sun—Hark to the musical
Behold the silvery river—in it the splashing horses, loitering, stop to drink;
Behold the brown-faced men—each group, each person, a picture—the negligent rest
Some emerge on the opposite bank—others are just entering the ford—while,
Scarlet, and blue, and snowy white,
The guidon flags flutter gaily in the wind.
