The activities of the Committee were similar to those during World War I: visiting and monitoring POW camps, organizing relief assistance for civilian populations, and administering the exchange of messages regarding prisoners and missing persons.
Kegiatan ICRC mirip dengan yang dilakukannya selama Perang Dunia I: mengunjungi dan memantau kamp-kamp POW, mengorganisir bantuan kemanusiaan bagi penduduk sipil, dan mengatur pertukaran berita terkait tawanan dan orang-orang hilang.
