The Croatian claim is that rumours coming from Serbia were the cause of the exodus. I doubt that can be documented either.

The Serbs of Croatia also took arms first, in the Log Revolution.

As a part of his plea bargain with the prosecution, Milan Babić testified against Martić during his ICTY trial, saying Martić "tricked him into agreeing to the Log Revolution". He also testified that the entire war in Croatia was "Martić's responsibility, orchestrated by Belgrade".
