And that it would be vigorously resisted there was every promise; for if Lee purposed making a stand between the North and South Anna, he would naturally seek to gain all the time possible in order to establish himself well in his new position.
Moreover, the North Anna covers the Virginia Centra the line of march of the army made a wide circuit eastward and then southward to pass the Pamunkey.
