 In modern days, a rafting photographer still uses pigeons as a sneakernet to transport digital photos on flash media from the camera to the tour operator.The pigeon post that was in operation while Paris was besieged during the Franco-Prussian War of 1870–1871 is probably the most famous.Barely six weeks after the outbreak of hostilities, the Emperor Napoleon III and the French "Army of Châlons" surrendered at Sedan on 2 September 1870.
