The Battle of Baçente was fought on February 2, 1542, when a Portuguese army under Cristóvão da Gama took a hillfort held by Adalite forces in northern Ethiopia.
Queen Seble Wongel (likely justifiably) advised against this attack, arguing that Gama should wait until her son the Emperor Gelawdewos could march north from Shewa and join the Portuguese due to Ahmed Gragn having known of them.
[1] However, Gama was concerned that if he marched around this Muslim-held strongpoint, the local peasantry would be disappointed and stop providing supplies for his troops.
"[1] A mosque, which had originally been a church before the hillfort was occupied by Imam Ahmad ibn Ibrahim al-Ghazi's men, was reconsecrated as a church, and dedicated to "Our Lady of Victory", and mass was celebrated there the next day.
Whiteway identified the Portuguese "Baçente" as referring to Amba Senayt in Haramat.
