Convinced of the imminence of the crisis and the peril of delay, Gen.
Lyon immediately commenced active operations against the secessionists
at Potosi, and ordered the seizure of the steamer which had supplied the
offensive army with material of war from the United States property at
Baton Rouge. In the meantime, Gen. Harney, with a culpable blindness,
had made an extraordinary arrangement with Gen. Price, by which he
pledged himself to desist from military movements so long as the command
of Gen. Price was able to preserve order in the State. Upon his removal

but retreated, after a skirmish which did not assume the proportions of
a battle; and the Union army, two thousand strong, entered the town,
where the national colors and the welcomes of the inhabitants testified
