Eumenes of Cardia vs Guo Huai

Eumenes was appointed as Alexander the Great's personal secretary (chief scribe) after the death of Philip II. This position gave him intimate knowledge of imperial administration and access to Alexander's inner circle.

Eumenes defeated Craterus and Neoptolemus at the Battle of the Hellespont. Craterus, Alexander's most trusted general, was killed in the battle. This victory established Eumenes as a major military commander in the Wars of the Diadochi.

After being declared an outlaw by Antipater, Eumenes was besieged by Antigonus Monophthalmus at the fortress of Nora in Cappadocia. He held out for over a year, negotiating a truce that allowed him to escape and continue his campaign.

Eumenes fought Antigonus Monophthalmus at Gabiene. Though the battle was tactically indecisive, Eumenes' own Silver Shields mutinied and handed him over to Antigonus, who had him executed. This ended his campaign.

After being betrayed by his own troops at Gabiene, Eumenes was executed by Antigonus Monophthalmus. His death removed the last major supporter of the Argead royal house and consolidated Antigonus's power in Asia.

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.
