Bottego then crossed the tract separating him from the Dawa, and ascended that river until lack of provisions compelled him to retrace his steps.

His party reached the Ganale Doria once more after six forced marches, in the course of which eleven men died of hunger.

[1] In his second expedition (1895–1897), Bottego ventured into the then unknown region of the upper Juba, Lake Rudolf and the Sobat.

He then tried to return through Ethiopia, unaware that the country was at war with Italy, let alone that there had been a recent Ethiopian victory at Adwa.

[3] Bottego is commemorated in the scientific names of two species of fishes: Neobola bottegoi [4] and Labeo bottegi.
