What message was sent to the gates by Ignosi?

Infadoos sent the message to the gate. 

So soon as we started Infadoos had despatched a runner to warn the people of the kraal, which, by the way, was in his military command, of our arrival. This man had departed at an extraordinary speed, which Infadoos informed me he would keep up all the way, as running was an exercise much practised among his people.
