Re slave armies.
The most famous was the elite of the Ottoman Army, the Janissaires, made up of children of Christian subjects of the Empire, recruite at age 10-11. So, in effect, slaves.
The novel, and upcoming film, [b]Ender's Game [/b]by Orson Scott Card, is based on this historical example (Card is controversial for his views re gay marriage etc. but he is a very good Science Fiction writer).
The Mamluks were slave warriors, who wound up taking over the state of medieval Egypt and making themselves emperor.
Most ancient armies had armed slaves who accompanied their masters into battle. Usually to finish off an opponent after the master had beaten him in single combat.
Slavery in the ancient world was seldom so defined as it was in the American south pre Civil War (and even there it varied very much between the brutal, huge, plantations on the Mississippi and say Virginia).
As to castrated soldiers can't think of an example. However Justinian's second best general (after Belisarius) in 5th century Rome/ Byzantium was Narses the Eunuch.

The worst are full of passionate intensity
And the best lack all conviction
All around is chaos
And the centre cannot hold
