Kirill Meretskov vs Shaka Zulu

Meretskov was arrested during the Great Purge and imprisoned. He was released in 1938 after confessing to fabricated charges, and was reinstated to the military, though his reputation was damaged.

Meretskov commanded the 7th Army during the Winter War against Finland. His forces failed to break the Mannerheim Line initially, leading to heavy Soviet casualties and his temporary relief from command.

Meretskov commanded the 1st Far Eastern Front in the Soviet invasion of Manchuria. His forces broke through Japanese defenses in the mountains and advanced into central Manchuria, contributing to Japan's surrender.

Shaka introduced the iklwa, a short stabbing spear, and the 'horns of the buffalo' tactical formation to the Zulu army. These innovations replaced the traditional throwing assegai and allowed for close-quarters combat, significantly increasing the Zulu's military effectiveness and enabling rapid conquest.

Shaka's Zulu army defeated the Ndwandwe kingdom at the Battle of Gqokli Hill, a decisive victory that eliminated a major rival. This conquest allowed Shaka to consolidate control over a large territory in present-day KwaZulu-Natal, marking the rise of the Zulu as a dominant regional power.

Shaka was assassinated by his half-brothers Dingane and Mhlangana, with the support of his aunt Mkabayi. The coup ended his reign of terror and expansionist wars, leading to a period of instability and the eventual rise of Dingane as king.
