2003–04 Indonesian offensive in Aceh

The 2003–2004 Indonesian offensive in Aceh against the Free Aceh Movement (GAM) separatists was launched May 19, 2003 and lasted nearly one year. It followed a two-week ultimatum to GAM to accept special autonomy under Indonesian rule. It was one of the Indonesian military's largest campaigns since the 1975 invasion of East Timor. It severely disabled the rebel movement, and along with the 2004 Indian Ocean earthquake brought the 30-year conflict in Aceh to an end.
