Allan and Jesse are assisted by Umslopogaas, a fearless warrior and old friend of Allan's, to put together an expedition. Swarma, a spiritual guru, and five Askari warriors, accompany them. The group crosses the Sahara desert; two Askari are lost when Swarma trips a trap that opens a pit under the road to the city. Another member of the party is lost when savage Esbowe warriors attack the group. Many spears are thrown at Quatermain and his friends, but Umslopogaas deflects most of them with his giant axe.
