The Battle of Adré took place in Adré, Chad on December 18, 2005. The battle began when the Chadian rebel groups Rally for Democracy and Liberty (RDL) and Platform for Change, Unity, and Democracy (SCUD), allegedly backed by the government of Sudan, attacked the garrison in this city. However, Chadian loyalists, who had been forewarned by military intelligence of the attack, easily repulsed the attackers. Either seventy, one hundred, or three hundred rebels were killed, depending on reports. Governmental losses are unknown, but they lost at least one Russian-made helicopter in a collision with electric wires during the fighting, while another Mil Mi-17 helicopter was heavily damaged by rebel fire which killed at least one crew member.
On December 19, SCUD leader Yaya Dillo Djérou said, "A few of our troops have participated in the action in Adré, but it is being led by RDL. Yesterday we took control of the city."
