Monument to the memory of the national guards killed in action on 19 January 1871 during the second battle of Buzenval, which took place during the Franco-Prussian war on the territory of the communes of Rueil-Malmaison, Garches and Saint-Cloud. The troops besieged in Paris tried to escape in the direction of Versailles. Following the unsuccessful attempt at Champigny a month and a half later, this second sortie, which was insufficiently prepared and of questionable strategic interest, was devised and led, in a politically divisive context, by General Louis Jules Trochu, Military Governor of Paris and President of the Provisional Government, to "calm down" the most bellicose Parisians. Its failure exacerbated the division between those in favour of a negotiated peace, who tended to be supported by the provinces and the army, and those in favour of "outrageous resistance", which included a majority of the Garde Nationale.
