Daniel H. Wells, general of the Territorial militia, the Nauvoo Legion (about 3000 troops), left SLC for Echo Canyon, 65 miles east, where he established headquarters. The militia he commanded employed various measures to block the progress of the army through the canyon.
Gov. Young wrote a Proclamation to the commander of the Utah Expedition explaining that he was the legitimate Governor and forbade the Army's presence in the Territory.
