Paris Gun
On 29 March 1918, a German shell, fired by the long-range "Paris Gun", fell on the church, killing 91 people and wounding 68 others; the explosion collapsed the roof when a Good Friday service was in progress. This was the worst single incident involving a loss of civilian lives during the German bombardment of Paris in 1918. Among those killed was Rose-Marie Ormond Andre-Michel, the niece and a favorite model of John Singer Sargent.
