Design

The French Army developed the St Chamond from the Holt tractor.

Colonel Rimailho designed the St Chamond.

The transmission added five tons to its weight.

Bogged Down

With the hull front and rear extending well out in front and behind the tracks caused the St Chamond to get stuck in rough terrain quite easily.

Armament

The 75 mm gun was located in the front and two machine guns were located on each side.

A prototype of the St Chamond first appeared in 1916.
