I had an interesting question come up yesterday whilst playing a game.
I placed a 35p wide river that ended up being in spate, therefore it was classed as difficult terrain for all troop types.
I had several groups up against the river line waiting to cross over.
However, when I attempted to cross it by wading, we could not find a specific rule that gave us the information how to do this other than you have to be between 45 and 90 degrees to the flow of the river before crossing.
So, my question is, how is the crossing performed? My opponent felt that you could not cross as a group, unless in column, only in single elements.
Can any one help?
