The movement for an international set of laws governing the treatment and care for the wounded and prisoners of war began when relief activist Henry Dunant witnessed the Battle of Solferino in 1859, fought between French-Piedmontese and Austrian armies in Northern Italy. The subsequent suffering of 40,000 wounded soldiers left on the field due to lack of facilities, personnel, and truces to give them medical aid moved Dunant into action. Upon return to Geneva, Dunant published his account "Un Souvenir de Solferino". He urged the calling together of an international conference and soon co-founded the International Committee of the Red Cross in 1863.
