In the night from the 22nd to the 23rd of June, 1871, towards one o'clock in the morning, the Paris suburb of Sauveterre, the principal and most densely populated suburb of that pretty town, was startled by the furious gallop of a horse on its ill-paved streets. A number of peaceful citizens rushed to the windows. The dark night allowed these only to see a peasant in his shirt sleeves, and bareheaded, who belabored a large gray mare, on which he rode bareback, with his heels and a huge stick.
