During October, Bradley incurred very heavy casualties in fighting in the Battle of Aachen and the Battle of Hürtgen Forest in October and November. This resulted in a critical shortage of infantry replacements even before the crisis situation created by the Ardennes Offensive. Noting that casualties among newly arrived reinforcements greatly exceeded those among veterans, Lee tried to humanize the replacement depots, and suggested changing the name so that they sounded less like spare parts. Bradley opposed this, arguing for more substantial changes.
