 The French had already conquered or taken over all of the surrounding kingdoms which trapped the Mossi kingdoms.The last king of Ouagadougou, named Wobgo or Wobogoo, was warned a day before the French forces were going to attack the city and so sent a small force to meet them in battle as he fled the city.The French fired four shots in the air which caused the Mossi force to scatter, but Wobgo was able to escape capture.
