Indy Journal Confusion

I'm currently working on my own Indy Journal and I've run into some confusion as to dating. The first is Attack of Hawkmen. The first half of the story is set in February, 1917 as evident by the calendar. Now, some sources I read put the second half as Alhorn - Late Feb, 1917, though some other sources put it in April, after Austria, but before Petrograd. The other thing I need to add and if anyone can help place them would be the levels from Instruments of Chaos on Genesis.

The dates I'm using:

Feb 1917 - Ravenel, France
March 1917 - Austria
April, 1917 (?) - Alhorn
May,1917 - Barcelona
July, 1917 - Petrograd
August, 1917 - Prague
October 1917 - Palestine
unknown date, 1917 - Morocco

Jan 1918 - Transylvania
March 1918 - Moscow
June 1918 - Italian Alps
September 1918 - Istanbul
November 1918 - Western Front

Jan 1919 - South Pacific
April 1919 - Bombay
May 1919 - Paris
Unknown date 1919 - Princeton
December 1919 - Havana

April 1920 - Chicago
June/July 1920 - New York
August 1920 - Hollywood/Mexico
December 1920 - Honduras

June 1921 - Alaska
December 1921 - Brazil

All of "Hawkmen" takes place in February 1917.

I've never played "Instruments of Chaos" but good ol' DIrishB placed it during March-April 1918.

Unicorn, if you want discuss more dating details, it would be good if The Mods merged your thread with this one: The Indiana Jones Timeline / Chronology

There's no official dates given in the game. It's just said that it's during Indy's tenure with French Intelligence, which puts it in the 1917/1918 bracket. So the Red Baron parts follow Early Feb 1917 and the Alhorn parts take place in Late Feb 1917.

Thanks Stoo.
