Hartmannswillerkopf, also known as the Vieil Armand (French) or Hartmannsweiler Kopf (German; English: Hartmansweiler Head) is a pyramidal rocky spur in the Vosges mountains of the Grand Est region, France. The peak stands at 956 metres (3,136 ft) overlooking the Rhine valley. At Hartmannswillerkopf stands a national monument of World War I for the fighting which took place in the trenches here.
The French and Germans fought for control of the mountain peak during the First World War. Fighting took place throughout 1915. An estimated 25,000 French soldiers died there.[1] After about 11 months of fierce combat, both sides began to focus most of their attention farther north on the Western Front. Only enough men to hold the lines were left at Hartmannswillerkopf. The lines remained relatively stable for the remainder of the war and generally only artillery exchanges took place.
Today, the area is a French national monument. There is a museum and a cemetery at the site, and it is also possible to explore the extensive trench system. Because the lines were static for such a long period, the trenches are very well preserved, especially on the German side of the front line.
There is a small memorial on the D431 north of Vieil Armand, commemorating Halifax bomber MZ807 of No. 433 Squadron RCAF, which crashed nearby in December 1944.
