Hunter dispatched a company of 60 soldiers to put down what they thought might become an armed rebellion, not what was an armed rebellion. The land that had been set aside for the refugees was not useable, so Hunter tried to secure additional land. Apparently the Palantines were not foresters, but were farmers, and many of their youngsters were apprenticed in Albany, while they were relocated to a pine forest area a good distance from Albany, where they were expected to produce products from pine trees. There was an unconnected "slave revolt" as well in NY and the militia turned out to put it down, so there were locals with arms. So perhaps the Palatines were not in possession of arms, but you don't have to be too sharp to hit a lone militia man in the head with a rock, and take his firelock, eh?
