Amr ibn al-As vs Yue Yi

Amr ibn al-As led the Muslim Arab army into Egypt, then a province of the Byzantine Empire. He defeated the Byzantines at the Battle of Heliopolis and captured the fortress of Babylon, leading to the surrender of Alexandria in 642.

Amr ibn al-As established the city of Fustat near the Nile Delta as the new capital of Muslim Egypt. The city became a major administrative and commercial center, later evolving into modern Cairo.

After the conquest, Amr ibn al-As was appointed governor of Egypt by Caliph Umar. He administered the province, implemented tax systems, and oversaw the construction of the Mosque of Amr ibn al-As, the first mosque in Africa.

Yue Yi formed a coalition of five states

Yue Yi led the coalition forces to a series of victories, capturing over 70 cities of Qi, including the capital Linzi. Qi was reduced to only two remaining cities, Ju and Jimo, and was on the verge of total annihilation.

King Zhao of Yan appointed Yue Yi as general to lead a campaign against the state of Qi. Yue Yi had previously served in Wei and Zhao, but his talents were recognized by King Zhao, who trusted him with the command of the Yan army.

After King Zhao of Yan died, his successor King Hui distrusted Yue Yi due to slander from Qi spies. Yue Yi fled to the state of Zhao to avoid execution. His departure allowed Qi to recover under Tian Dan and recapture its lost cities.
