Prince (Leul) Asfawossen Kassa was the third son of Duke (Ras) Kassa Haile Darge.
During the Second Italo-Ethiopian War, Asfawossen Kassa fought for his father. At the Second Battle of Tembien, the armies of his father and Ras Seyum Mangasha were defeated in battle and bombed out of existence as they withdrew. During the early days of the Italian occupation of Ethiopia, Asfawossen Kassa was part of the armed Ethiopian resistance.
After the failure of that attack, he and Aberra Kassa fled together to avoid capture.
On 21 December 1936, Asfawossen Kassa and Aberra Kassa surrendered. They had been assured by Ras Hailu Tekle Haymanot that they would not be harmed.
Hailu Tekle Haymanot was speaking on behalf of the Italian Viceroy and Governor-General of Ethiopia, Rodolfo Graziani. However, once in captivity, the bodyguards of the brothers were disarmed and they were executed as rebels in the market square in Fikke.
