The allied forces spent the following months marching the provinces before heading to Imam Ahmad's camp next to Lake Tana. On 13 February 1543, they defeated a group of cavalry and infantry led by the Imam's lieutenant Sayid Mehmed in Wogera (roughly corresponding to the modern woreda of the same name), killing Sayid Mehmed. From the prisoners it was learned that the Imam was camped only 5 days' march away at Deresgue, and flush with victory the army marched to confront their enemy.
