[Dr. Livingstone seems to have been unable to find opportunity to make
daily entries at this period. All was turmoil and panic, and his life
appears to have been in imminent danger. Briefly we see that on his
way back from the Lake he found that his Arab associates of the last
few months had taken up Casembe's cause against the devastating hordes
of Mazitu, who had swept down on these parts, and had repulsed them.
But now a fresh complication arose! Casembe and Chikumbi became
alarmed lest the Arabs, feeling their own power, should turn upon them
and possess the whole country, so they joined forces and stormed
Kombokombo, one of the leading Arabs, and with what success we shall
see. It is a fair specimen of the unaccountable complications which
dog the steps of the traveller, where war is afoot, and render life a
misery. He writes as follows on the 5th October:--]

I was detained in the Imbozhwa country much longer than I relished.
The inroad of the Mazitu, of which Casembe had just heard when we

feeling grateful, hated the new power thus sprung up among them! They
had suffered severely from the sharp dealing of the strangers already,
and Chikumbi made a determined assault on the stockade of Kombokombo
in vain.

Confusion prevailed all over the country. Some Banyamwezi assumed the
offensive against the Bauesi, who resemble the Imbozhwa, but are
further south, and captured and sold some prisoners: it was in this
state of things that, as already mentioned, I was surrounded by a
party of furious Imbozhwa. A crowd stood within fifteen or twenty
yards with spears poised and arrows set in the bowstrings, and some
