Battle of Jassin

Battle context

The Battle of Jassin was an early engagement of the East African campaign of World War I, fought along the border between British East Africa and German East Africa. A British garrison of four Indian companies, numbering just over 300 men under Colonel Raghbir Singh, had occupied Jassin to secure the frontier but was weakly positioned when a German Schutztruppe force of approximately 1,350 under Paul von Lettow-Vorbeck engaged them in January 1915. The British and Indian troops suffered 276 casualties, including the death of the commanding officer Colonel Singh, against German losses of around 200. The disparity in force size and the fall of the garrison commander underscored the vulnerability of thinly held border posts in the theater, and the engagement reinforced Lettow-Vorbeck's approach of aggressive forward operations to tie down British resources in East Africa rather than ceding the initiative to the numerically superior imperial forces.
