The Red Cross created portable base hospitals for the Army, consisting of staff, tents, and supplies. In North Carolina some $2 million was raised by individuals, as well Red Cross groups, to pay for the hospitals. North Carolinians also contributed almost two million surgical dressings, over 100,000 hospital garments, and about 100,000 knitted socks, hats, and gloves. In field units just behind the lines and at base hospitals further back, nurses worked endless days and nights to help mend the sick and wounded.
