"Uncle Alf" (2002) is an alternate history short story by Harry Turtledove.
It was first published in Turtledove's edited anthology Alternate Generals II in 2002 and was later reprinted in his short story collection Atlantis and Other Places in 2010.
[1][2][3] The point of divergence occurs in 1913 when Alfred von Schlieffen, who in real life died in 1913, survives to personally oversee the successful implementation of his famous plan for two-front war against France and Russia.
Two years later in 1916, an earlier communist revolution erupts in Russia, Kaiser Wilhelm II (fearing the consequences within his country's own borders if the Russian Empire collapsed) helps his cousin and former enemy Tsar Nicholas II to crush it quickly.
The main action of the story itself is set in May of 1929, as sergeant Adolf Hitler of the Feldgendarmerie is sent to Lille in pursuit of communist agitator Jacques Doriot.
