Louis Antoine Fauvelet de Bourrienne, Memoirs of Napoleon Bonaparte…
“ For the first time Napoleon had recourse to an expeditious mode of transport, and 20,000 carriages conveyed his army, as if by enchantment, from the shores of the Channel to the banks of the Rhine. The idea of an active campaign fired the ambition of the junior part of the army. All dreamed of glory, and of speedy promotion, and all hoped to distinguish themselves before the eyes of a chief who was idolised by his troops. Thus during his short stay at Strasburg the Emperor might with reason prophesy the success which crowned his efforts under the walls of Vienna. ”
