Cavalry Crossing a Ford

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 clank;
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 on the saddles;

Some emerge on the opposite bank--others are just entering the
   ford--while, 5
Scarlet, and blue, and snowy white,
The guidon flags flutter gaily in the wind.
