The Battle of Mengo Hill refers to the successful 1966 assault upon the residence of the Kabaka of Buganda by the army of Uganda.
In February 1966, Prime Minister Milton Obote had changed the constitution, taking the powers of the presidency, formerly held by the Kabaka, for himself. The Kabaka is the ruler of Buganda, the largest and most influential of the five traditional kingdoms within Uganda, and the capital of the kingdom, Kampala, is also the capital of the country. The Kabaka at the time was Mutesa II. Kabaka Mutesa II protested Obote's actions, ordering Obote to leave Buganda lands and appealing to United Nations Secretary-General U Thant to intervene. Obote immediately accused the Kabaka of high treason and ordered his protégé, Idi Amin Dada, to lead troops against the Kabaka's residence on Mengo Hill, which was promptly surrounded.
The Kabaka called for his subjects to defend him, and many responded by acts of sabotage throughout Buganda, while thousands of monarchists attempted to set up blockades to hinder Amin's troops and engaged in running street skirmishes. However, the Kabaka's bodyguards were lightly armed with hunting rifles, especially as compared to the army units and, two days after the palace was surrounded, the palace was overrun and set alight. Kabaka Mutesa II himself escaped the compound during a cloudburst in the middle of the battle.
"When Obote sent his soldiers to bring Mutesa to him ‘dead or alive’ the King was unprepared. Out numbered, with only 120 guards and facing the Uganda Army with its Lee–Enfield rifles, three carbines, six Sterling machine guns and six automatic rifles, it was a losing battle. Determined to protect the King, the [royal] guards knew the only option was for him to flee. Rain connived with the royals, as it slowed the attackers’ advancement. Jumping over bodies as they fled, Mutesa and 20 royal soldiers hauled each other over the six foot high brick walls of the palace. Unfortunately, Kabaka Mutesa landed in a precarious angle that left his back bone injured. But the king was free and that’s all that mattered."
