Battle Record
The following information was taken from the Historique du 151e Regiment d'Infanterie by Jean Lieffroy (the unofficial regimental historical published in 1997), the official regimental historical published in 1919, and the official war-time campaign journal referred to as the Journal des Marches et Operations (JMO). When available, casualty figures are given, drawn from these three sources. The casualty percentages are estimates, as the exact number of the regiment's effectives at any given time are not always known.
