The 9th Company was a unit of the 3rd battalion RMT, part of the French 2nd Armored Division.
During the move on Paris, due to combat conditions and poor road progress, General Philippe Leclerc, commanding general of the Second Armored, ordered Dronne to form an advance party, go to Paris and let the Resistance know that the Second Armored would be in Paris in 24 hours.
His advance party, the 9th Company, consisted of armoured cars, and Sherman tanks from another regiment of the division.
The armored cars were called Guadalajara, Madrid and Ebro and the added Sherman tanks were called Montmirail, Romilly and Champaubert.
