The logistic prelude to the Meuse attack was planned by then U.S. Colonel George Marshall who managed to move American units to the front after the Battle of Saint-Mihiel (Saint-Mihiel is a town on the river Meuse, the most important water obstacle on the Western Front). The September/October Allied breakthroughs (north, center, and east) across the length of the Front line – including the Battle of the Argonne Forest – are now lumped together as part of what is generally remembered as the Grand Offensive (also known as the Hundred Days Offensive) by the Allies on the Western Front. The Meuse–Argonne offensive also involved troops from France, while the rest of the Allies, including France, Britain and its dominion and imperial armies (mainly Canada, Australia, and New Zealand), and Belgium contributed to major battles in more North-Western sectors of the western front, including the Hindenburg line.
