Battle of Dioubouldou
The Battle of Dioubouldou was fought on 25 February 1855 between French forces of Colonel Louis Faidherbe and the combined Waalo and Trarza forces under Queen Ndaté Yalla Mbodj.
Background
Although they were historical enemies, relations between Waalo and Trarzas had recently got a bit warmer when Mohamed El-Habib married the sister of Queen Ndaté. Together, they started challenging the growing influence of the French in the vicinity of Saint-Louis.In January 1855, Queen Ndaté sent an imperious letter to French governor Louis Faidherbe, ordering him to evacuate the outskirts of Saint-Louis immediately. In response, Faidherbe gathered troops and local volunteers and departed from Saint-Louis in order to march on N'Der, the village of Queen Ndaté.
Battle
On 25 February, the French column, composed of 400 regulars, 400 volunteers from Saint-Louis and a platoon of colonial cavalry, met with the Waalo-Trarza army near a wood in the plain of Dioubouldou, not far from N'Der. Queen Ndaté's forces had been waiting here for French. Trarza cavalry was positioned at the center, while Waalo infantry was disposed on each sides of the cavalry. A large number of Waalo warriors were also hidden in the field of tall grass that separated the French from the Waalo-Trarza army.Colonel Faidherbe started by firing some artillery rounds on the field, which caused great disorder in Waalo ranks. He then sent a company of marines under Captain Benoit and a group of volunteers led by a man named Amadou Sar to attack the warriors in the grass. Meanwhile the French rearguard, which consisted in a company of marines under Captain Bruyas, easily repulsed an attempt at envelopment by Trarza cavalry. French cavalry was then sent against the retreating Waalo warriors, turning their flight into a complete rout.
