William E. Barton, The Life of Clara Barton, Founder of the American Red Cross… (1922)
“ This land, as the property of the American National Red Cross, will be the one piece of neutral ground on the Western Hemisphere protected by international treaty against the tread of hostile feet. It is a perpetual sanctuary against invading armies, and will be so respected and held sacred by the military powers of the world. Forty nations are pledged to hold all material and stores of the Red Cross, and all its followers, neutral in war, and free to go and come as their duties require. ”
