The monument was inaugurated in 1928 to commemorate this battle which cost the lives of more than 500 French soldiers and 100 Germans, during the second advance of French troops on Mulhouse, in an Alsace which had remained German since the 1871 Treaty of Frankfurt. In 1939, the medallion of General Plessier, the first French senior officer to be killed during the Great War, mortally wounded between Walheim and Wittersdorf on 19 August 1914, was affixed to the hill.
