surprise was complete and its success overwhelming. French and British
troops reeled back day after day in stunned confusion. The head of
intelligence at French G.H.Q. came into the cryp-tologic bureau three

Marcel Givierge, and Soudart's assistant, Marcel Guitard: "By virtue of
my job I am the best informed man in France, and at this moment I no
longer know where the Germans are. If We're captured in an hour, it
wouldn't surprise me." Within a week the Germans had punched a hole
38 miles deep in the Allied lines, and it was not until the British and
French
troops fell back to Amiens that they collected themselves and halted
the advance.
