I have a nice little book detailing the French order of battle for the Saar Offensive and I can't seem to find it. Off the top of my head, I recall that element of 9th Corp, along with the 11th and 21st I.D. participated as well as units of Algerian and Senegalese troops.

Most of my sources indicate similar numbers of casualties for the Saar Offensive, around 1,100 -1,500.
