It is interesting to note that Quote" In the 16th century, Adal organised an effective army led by Imam Ahmad ibn Ibrahim al-Ghazi that invaded the Abyssinian empire. This campaign is historically known as the Conquest of Abyssinia or Futuh al Habash.
During the war, Ahmed pioneered the use of cannons supplied by the Ottoman Empire, which were deployed against Solomonic forces and their Portuguese allies led by Cristóvão da Gama.
Some scholars argue that this conflict proved, through their use on both sides, the value of firearms such as the matchlock musket, cannons and the arquebus over traditional weapons.
