In 1872, there was reason to fear that the expedition of the American, Stanley, was in great danger.

It had been sent to the great lake region in search of Livingstone.

Lieutenant Cameron offered to go over the same road.
The offer was accepted.

Cameron, accompanied by Dr.Dillon, Lieutenant Cecil Murphy and Robert Moffat, a nephew of Livingstone, started from Zanzibar.

After having crossed Ougogo, he met Livingstone's faithful servants carrying their master's body to the eastern coast.
