 On 13 June, the expedition entered the White River and proceeded uneventfully upstream for four more days.With intent only to slow down the progress of the Union vessels and not to make a determined stand, the Confederates had set up a pair of batteries on the bluffs near St. Charles, Arkansas, some 80 miles (130 km) above the river mouth.The guns were taken from a gunboat which they had then scuttled in the middle of the stream as a further impediment.
