He then reduced the number of mercenary Ottoman arquebusiers to 200, and relying on his own forces retired to Emfraz near Lake Tana for the coming rainy season.
Miguel de Castanhoso states that these arquebusiers left his service because they were upset that he beheaded da Gama, whom they wanted to present to the Ottoman emperor.
When the rest of the group learned of their success, they came to the Imam and made a similar demand; deciding that he had no further need of their services, he sent them home giving them 2,000 ounces of gold.
[6] However, de Gama had inspired a fierce loyalty in his surviving followers, all but 50 of whom had reassembled after their defeat around Queen Seble Wongel, and taken refuge at "The Mountain of the Jews", which Whiteway identifies as Amba Sel.
A message was sent to a company of Portuguese soldiers who had proceeded to Debarwa to find passage home, but they failed to respond in time for the coming battle.
[11] Richard Pankhurst in The Ethiopian: A History places the engagement in "Western Bagemder", which covered the area corresponding to the contemporary Debub Gondar Zone.
"[15] However, as Whiteway points out, "The difficulty that presents itself to my mind is, to understand by what possible strategy one army starting from Darasgue, and the other from Woggera, neither desiring to avoid an engagement, and both starting-places being north of Lake Tzana, the decisive battle could have taken place at its south-west corner.
[17] Whiteway notes that two explorers, Combes and Tamisier, who crossed the mountainous country north-east of Lake Tana in 1835 call that region "Ouenadega" or Wayna Daga, and he concludes his discussion by locating the battle there.
The Portuguese, seeing that the Muslims were prevailing, charged them, slaying many and driving the rest back; the Abyssinians, ashamed to see them fight alone, threw themselves in so vigorously that they left a "track as they went".
Joram had driven Gelawdewos "from his hiding-place on Mount Tsalem, and forced him to cross the Tacazze on foot, with equal danger of being drowned or taken."
"[29] The father of the Bahr negus, who had despaired of the rightful Emperor being restored to power and had come to be a valuable supporter of the Imam, sought pardon from Gelawdewos, offering Imam Ahmad's son in exchange; despite the Emperor's anger at the man's betrayal, out of respect for the Bahr negus, who had provided critical help in getting the Portuguese expedition into Ethiopia, Gelawdewos consented to the offer.
[30] A number of other Christians who had joined Imam Ahmed Gragn accompanied the Bahr negus' father into camp, but not having the influence or bargaining chip he did, the Emperor ordered the execution of some of them.
"[31] By Easter (25 March), it became clear to Gelawdewos that he would not be able to make a circuit of his newly-won empire to impress his authority on all parts of it before the start of the rainy season, so he set up camp "three leagues away" in an unnamed location on the shores of Lake Tana.
