The light cavalry was not the only units ordered to leave their eagles in depot. After the 9th Leger lost their regimental colors in the winter of 06/07 Napoleon had a melt down, until it was learned the eagle had been removed from the flag staff for repairs to damage caused by a musket ball. I do not have the dates but the Leger infantry were ordered to leave all their eagles in depot and only allowed one standard in the field.
