Winnie-the-Pooh is the first volume of stories about Winnie-the-Pooh,
by A. A. Milne. It is followed by The House at Pooh Corner. The book
focuses on the adventures of a teddy bear called Winnie-the-Pooh
and his friends Piglet, a small toy pig; Eeyore, a toy donkey; Owl, a
live owl; and Rabbit, a live rabbit. The characters of Kanga, a toy
kangaroo, and her son Roo are introduced later in the book, in the
chapter entitled "In Which Kanga and Baby Roo Come to the Forest
and Piglet has a Bath." The bouncy toy-tiger character of Tigger is
not introduced until the sequel, The House at Pooh Corner. Portions
of Winnie-the-Pooh were adapted from previously published magazine
stories.

Sergeant Stubby was a stray Pit Bull/Terrier mix,that became the most decorated
war dog of World War I and the only dog to be promoted to sergeant through
combat. He served 18 months ‘over there’ and participated in seventeen battles
on the Western Front. He saved his regiment from surprise mustard gas attacks,
found and comforted the wounded, and even once caught a German spy by the
seat of his pants, holding him there until American Soldiers found him. Back home
his exploits were front page news on most major newspapers.  

Stubby was wounded in the foreleg by the retreating Germans throwing hand
grenades. He was sent to the rear for convalescence, and as he had done on
the front was able to improve morale. When he recovered from his wounds,
Stubby returned to the trenches.

Upon returning home, Stubby became a celebrity and marched in,
and normally led, many parades across the country. He met with 
Presidents Woodrow Wilson, Calvin Coolidge, and Warren G.
Harding.
