“Here We Drown Algerians.” That chilling claim was actually written on the side of the Quai Conti in Paris, and then immortalized in Jean Texier’s snapshot. It refers to one of the darkest incidents in recent French history: the attack by French police on a peaceful march by Algerians supporting the independence of their country on October 17, 1961. Many marchers died on the streets, while other jumped or were forced into the Seine, resulting in even more deaths. Remarkably, news reports of this tragedy were largely quashed, and it remained unknown until a series of articles and books appeared in the early 1990s. Drawing on some remarkable period footage and photographs, as well as interviews with some of survivors and their families, Yasmina Ada offers a richly detailed account of the events leading up to the march as well as the cover-up and its aftermath.
