Invading powers were much more easily frustrated when an indigenous force chose to wage a guerrilla war instead of committing to pitched battles, such as in the Franco-Hova Wars or the First Indochina War. Indigenous leaders such as Abdelkader ibn Muhieddine of Algeria, Mahmadu Lamine of Senegal, and Samori Ture of the Wassoulou Empire were able to resist European colonialism for years after disregarding traditional methods and using guerrilla tactics instead. In practice, regular and irregular forms of warfare generally happened within quick succession of one another. A handful of traditional battles were won by indigenous Asian and African forces with numerical superiority or the element of surprise over colonial powers, but over time they faced staggering losses and discouraging defeats. Such trends were marked by the German suppression of the Maji Maji Rebellion, the defeat of the Zulus at the hands of British forces at the Battle of Rorke's Drift, and the destruction of Mahdist cavalry by British Maxim machine guns at the Battle of Omdurman.
