Henry Dunant: Du rouge sur la croix

Henry Dunant, a Genevan bourgeois, works for a Swiss company in French Algeria and determines to convince the firm and emperor Napoleon III to build a dam for the colonists. On his way to the emperor, he gets stuck in Austrian Castiglione which French troops came to 'liberate'. His letters home, published in Geneva, the shocking first-hand truth about war cruelty, start enough public commotion to make his plans eventual turn true in the form of the now worldwide International Red Cross.
