H. W. Halleck,
Elements of Military Art and Science
“ We will suppose war to be declared, and the army to be just entering upon a campaign. The political and military authorities of the state determine upon the nature of the war, and select the theatre of its enterprises. The chief selects certain points, on or near the borders of the seat of war, where his troops are to be assembled, and his materiel collected. These points, together, form his base of operations. ”
