Cause

Somalia launched a military invasion of the Ogaden region in July 1977 in support of the Western Somali Liberation Front insurgency, seeking sovereignty over the ethnically Somali-populated territory held by Ethiopia. The Soviet Union, previously a patron of Somalia, withdrew its backing and shifted support to Ethiopia in response to the invasion.

Event

Somali National Army forces rapidly advanced into the Ogaden, achieving initial gains before a Cuban-Ethiopian counteroffensive reversed their progress. A Cuban armored force equipped with 300 tanks, 156 artillery pieces, and 46 combat aircraft inflicted decisive defeats on Somali units at Harar and Jijiga. On 23 March 1978, Ethiopia declared the last border post recaptured, ending the conflict.

Consequence

Somalia lost approximately one-third of its regular army, three-eighths of its armored units, and half of its air force. The military defeat left the armed forces demoralized and disorganized, fueling an internal revolt that eventually contributed to the collapse of the Somali state and the onset of the ongoing Somali Civil War.
