town belonging to the Moors, who, being always professed enemies to the Christians, began to thwart the designs of the Portuguese as they had formerly done in India.  They even attempted to poison the Portuguese army, and some of the men and horses actually died in consequence; but the cause being discovered by one of the Moors, they were all put to the sword, their chiefs being blown from the mouths of cannon, the informer only being pardoned.  After this Barreto sent an embassy to the king, desiring permission to march against the chief of the Mongas, who was then in rebellion, and from thence to continue his march to the mines of Butua and Mancica.  The first of these requests was a piece of flattery to obtain leave for the other, as the province of the Mongas lay between Sena and the mines, and it was necessary to march thither by force of arms.  The king gave his consent to both requests, and even offered to send 100,000 of his own men along with the Portuguese; but Barreto declined any assistance, wishing to have the whole honour of the war to himself, and thinking by that means to gain favour with the king.  He accordingly marched with 23 horse and 560 foot armed with muskets; and after a march of ten days, mostly along the rapid river Zambeze, in which the troops suffered excessively from hunger and thirst, the enemy were descried covering the hills and vallies with armed men.  Though the multitude of the enemy was so great that the extremity of their army could not be seen, Barreto marched on giving the command of the van to Vasco Fernandez Homem, while he led the rear in person, the baggage and a few field pieces being in the centre.  On coming up to engage the cannon were removed to the front and flanks.

The enemy were drawn up in the form of a crescent; and as the Portuguese marched to the charge, an old woman came forward to meet them scattering some powder towards them, having persuaded the enemy that she alone would gain the victory by virtue of that powder.  Barreto understood the meaning of this superstitious act, having seen similar things in India, and gave orders to level a field piece at the notorious witch, which was so well pointed that she was blown to atoms, at which the Kafrs were astonished, as they believed her immortal.  The enemy however advanced, but without any order, either from ignorance or because they relied on their immense numbers, and discharged clouds of arrows and darts against the Portuguese; but finding that the musqueteers slew them by hundreds at every discharge, they took to flight, and great numbers of them were slain in the pursuit.  Barreto continued his march for the city of the Mongas, and was opposed by another multitude similar to the former which was put to flight with equal facility, above 6000 of the Kafrs being slain with the loss of only two Portuguese soldiers.  The city was abandoned by the enemy and taken possession of by Barreto without opposition, at which he entrenched his small army.
