Today is Lumumba's death anniversary. And I have been searching for first hand material on Lumumba...till I found one precious today!
Lumumba wrote a book which was published only after his death. The publisher, in 1962, included his correspondence with Lumumba about the manuscrit.
I would like also to take this opportunity to salute Franziska Seel who was encouraging me to search more on Lumumba.
Here is poem writen by an Indonesian poet at the announcement of Lumumba's death:

The news came early in the morning.
Lumumba is dead
Lumumba is dead

Anger split the whole world asunder.
A worker shouts:
who can murder my age --
the rails of the trains
the length of the light of the sun
we are all Lumumba
Lumumba.

A peasant stamps his feet
the people never die --
the heart is in the paddy
growing along in struggle and song

Freedom that's Lumumba
Lumumba.

The news came early in the morning
Lumumba is dead
Lumumba is dead
the earth shook
the revolution marches on.

Long live Lumumba.
