Ahmad Gragn, certain that the surviving Portuguese are scattered, without their firearms, and alone in a foreign land, concludes that this threat is ended, dismisses all but two hundred of the foreign musketeers, and proceeds to his camp at Derasge on the shores of Lake Tana.

However, over one hundred and twenty men have joined Queen Sabla Wengel, who has taken refuge at the Mountain of the Jews.

Ten days later, her son, Emperor Gelawdewos, arrives and they take measure of their situation.

Using the arms stockpiled at Debre Damo, the Portuguese are able to rearm themselves; with the promise of their ability, Gelawdewos is able to raise a new army, which meets Ahmad Gragn at Wayna Daga on February 21, 1543.

The Portuguese musketeers aim their fire only at the Muslim musketeers, who had played a decisive part at Wofla—and at Imam Ahmad himself.

While the sources differ on the exact details, all agree that Cristóvão da Gama’s men killed Ahmad Gragn to avenge their commander's death.

Gelawdewos had devoted time and energy to rallying his people against Ahmad, a determination his chronicler credits with preventing Ahmad's forcible conversions from being permanent.

With Ahmad's death, Gelawdewos is not only able to eject the leaderless Muslim forces from the Amhara plateau, but also from the lowlands to the east, which include Dawaro and Bale.

The Ottomans, who had in 1541 contributed a force of nine hundred musketeers but have their own troubles to deal with in the Mediterranean, are unable to help Ahmad's successors.
