Sending 2nd army to Serbia first. The delay in shifting them to Galicia forced 3rd army to face two Russian armies alone. So 4th army had to be diverted from its near total victory at Kamorov (sp?) and let the Russian 5th army live to fight another day...that day being when the 4th Austrian was engaged with another Russian army and caused a route back to the Carpathians. 2nd Austrian when it showed up got caught in the flight to the San river and wasn't able to alter the situation except put a floor on how bad the defeat was.
This thread on AH.com is a good alternative history scenario covering what if 2nd army went to Galicia instead:

I've decided to rewrite my original version of this TL, so I'm going to start a new thread.

Apologies for asking, but did you yourself make that thread on AH.com?
