Probably from Canrobert's memoirs. Talking about the capture of Constantine in 1836, he writes
It were buried … and the commandant of engineers Vieux, a giant, hero of Waterloo. There he had thrust open with a push of his shoulder the gate of Hougoumont, which was tenaciousy defended by the English.On enterra le général de Caraman, le commandant de Serigny et le commandant du génie Vieux, un géant, héros de Waterloo. Il y avait enfoncé d'un coup d'épaule la grande porte de la ferme d'Hougoumont, opiniâtrément défendue par les Anglais.
