the army corps were (1) MacMahon, (2) Frossard, (3) Bazaine, (4)
Ladmerault, (5) Failly, (6) Canrobert, and (7) Felix Douay. Both Frossard
and Failly, however, were at first made subordinate to Bazaine. The head
of the information service was Colonel Lewal, who rose to be a general and
Minister of War under the Republic, and who wrote some commendable works
on tactics; and immediately under him were Lieut.-Colonel Fay, also
subsequently a well-known general, and Captain Jung, who is best
remembered perhaps by his inquiries into the mystery of the Man with the
Iron Mask. I give those names because, however distinguished those three
men may have become in later years, the French intelligence service at the
outset of the war was without doubt extremely faulty, and responsible for
some of the disasters which occurred.

On returning to Paris one of my first duties was to go in search of
Moulin, the detective-artist whom I mentioned in my first chapter. I found
him in his somewhat squalid home in the Quartier Mouffetard, surrounded by
a tribe of children, and he immediately informed me that he was one of the
"agents" appointed to attend the Emperor on the campaign. The somewhat
lavish Imperial _equipage_, on which Zola so frequently dilated in "The
Downfall," had, I think, already been despatched to Metz, where the
Emperor proposed to fix his headquarters, and the escort of Cent Gardes
was about to proceed thither. Moulin told me, however, that he and two of
his colleagues were to travel in the same train as Napoleon, and it was
agreed that he should forward either to Paris or to London, as might prove
most convenient, such sketches as he might from time to time contrive to
make. He suggested that there should be one of the Emperor's departure
from Saint Cloud, and that in order to avoid delay I should accompany him
on the occasion and take it from him. We therefore went down together on
July 28, promptly obtained admittance to the chateau, where Moulin took
certain instructions, and then repaired to the railway-siding in the park,
