Ankus

[Jens Nordlunde]

Yes ancuse' could have fire arms attached, although it was not the norm. However, should someone directing an elephant feel attached, he would use the ancus to defend himself and his master, as he would likely not be armed with anything other than a dagger. The ancus would have been a rather good weapon, as it had the spikes. Getting a blow if one of these spikes would not have been very pleasent.
It is, however, likely that the elephant would have run away before such a thing happend, due to the battle noice and the firering of guns and cannons.
