Amr ibn al-As vs Guo Huai

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.

Guo Huai served under Cao Zhen during the first Shu invasion. He provided reinforcements to Zhang He at Jieting, where Zhang He defeated Ma Su, forcing Zhuge Liang to retreat. This victory secured Wei's western border.

Guo Huai defended against Zhuge Liang's second northern expedition. He held the strategic position of Mount Qi, repelling Shu attacks and inflicting heavy casualties. Zhuge Liang withdrew due to supply issues.

Guo Huai participated in the defense against Zhuge Liang's final northern expedition. He commanded a section of the Wei army and helped maintain the stalemate that led to Zhuge Liang's death and the Shu retreat.

Guo Huai led Wei forces against Jiang Wei's invasion of Longxi. He used a pincer movement to trap Jiang Wei's army, forcing him to retreat with heavy losses. This victory solidified Wei control over the western regions.

Guo Huai was appointed Grand Commandant, one of the highest military offices in Wei. He continued to oversee western defenses until his death later that year, maintaining stability against Shu incursions.
