He was sent back to his own country with a Portuguese squadron of twenty caravels, which had for its instructions, besides his restitution, to found a fort on the banks of the river Senegal.
The Portuguese arrived at the river, and began building the fort, but are said to have chosen an unhealthy spot to build on.

Whether they could have chosen a healthy one is doubtful.

The commander, however, Pedro Vaz, thought that there was treachery on Bemoin's part, and killed him with the blow of a dagger on board his vessel.

The building was discontinued, and Pedro Vaz returned to Portugal, where he found the king excessively vexed and displeased at the fate of Bemoin.

We have seen it making its way with quiet perseverance, for seventy years, from Cape Nam to the Cape of Good Hope, a distance of some six thousand miles.
