Hattusili I
The Hittite king Hattusili I exploited Alalakh's proclamation of sovereignty and the internal dissent it caused in Yamhad. He attacked Alalakh in the second year of his Syrian campaigns and conquered it, cutting Aleppo's route to the sea. Yarim-Lim did not send troops to aid Alalakh and the city was destroyed. He (Hattusili) then attacked Urshu. Yarim-Lim and Carchemish sent aid to the city in vain, and Hattusili destroyed it.
