The Battle of Galidraan was a conflict that led to the destruction of the Mandalorians by the Jedi. The Jedi were led by Master Dooku, with his last padawan Komari Vosa . The Mandalorians followed Jango Fett. The casualties on both sides were heavy, with Jango being the only surviving Mandalorian. The Jedi handed Jango over to the Governor of Galidraan, and the Mandalorian was sold into slavery.
Dooku would later reflect that "It was a misguided mission from the start and not the first of the Council's poor decisions."
