According to the "Cracked" website [quite reliable, in spite of the name], "A.A. Milne, acclaimed children's author and creator of Winnie the Pooh, was known to view his billion-dollar bear with the frothing dislike of a thousand exploding bile factories. This is actually pretty impressive, considering some of the other stuff he penned.
"Recently found documents reveal that, during World War I, the famously pacifist Milne worked for MI7b,
a top secret British military intelligence unit that specialized in
maintaining morale via misinformation. The group consisted of 20 or so
top British writers of the time, and their sole purpose was to create
newspaper articles and treatises that were so skillfully crafted, they
could not be recognized as propaganda."
