and McCulloch strongly disagreed over command issues. Price would move towards Kansas, fearing a counterstroke from Union troops there, leaving McCulloch with an army that soon dwindled after terms of enlistments expired and some of the remaining troops were reassigned elsewhere. Price followed up Wilson's Creek with a strike northwards towards the Missouri River, and was victorious at the Siege of Lexington.
