Prester John was there, or if any one knew where he was to be found,
and on the promise of a splendid reward, in case of success, this was
readily undertaken.

The conclusion of the adventure of Bemoy, was extremely tragical.
A quarrel having arisen between him and the commander of the
expedition, the latter stabbed the African prince on board his own
vessel. Whether this violent deed was prompted by the heat of
passion, or by well-grounded suspicions of the prince's fidelity, was
never fully investigated, but the king learned the event with great
regret, and in consequence, gave up his design of building a fort on
the Senegal. Embassies were, however, sent to the most powerful of
the neighbouring states, nor was any pause made in the indefatigable
efforts to trace the abode of Prester John. Amongst the great
personages, to whom an embassy was sent, are mentioned the kings of
Tongubutue, (Timbuctoo,) and Tucurol, a Mandingo chief named
Mandimansa, and a king of the Foulhas, with all of whom a friendly
intercourse was established. All endeavours were, however, vain as to
the primary object, but the Portuguese thereby gained a more complete
knowledge of this part of interior Africa than was afterwards
attained in Europe till a very recent period.

There is, however, one circumstance attending these discoveries of
the Portuguese, and the embassies, which they in consequence sent to
the native princes, which deserves particular attention. There is
very little doubt existing, but that the Portuguese were acquainted
with the town and territory of Timbuctoo; and the question then
presents itself, by what means did the Portuguese succeed in
penetrating to a kingdom, which, for centuries afterwards, baffled
all the efforts of the most enterprising travellers to arrive within
