In the rules it says that any foot can interpenetrate Artillery perpendicularly front to back or back to front. Since those mean completely different things... Should that be parallel meaning they cannot do so at an angle?

Probably not a topic that comes up much... but should be added to the errata if that is the case.

Thanks,

It means not side to side or at any other angle than from their rear edge to their front edge, directly. Or vice versa. So nothing else is needed.

At an angle could be 90 degrees, 180 degrees, 124 degrees, 327 degrees. So at an angle means nothing.

What is confusing is that the word Perpendicular means at a 90 degree angle... it is not possible to be both perpendicular and front to back or back to front. We started at each other after reading the first part thinking it meant we can only march directly across the artillery then saw the second bit which made alot more sense but was un-perpendicular.

Perhaps it should say 'may interpenetrate perpendicular to the front or rear edge'? But that would be harder for people to understand tho grammatically more correct

I think they mean that the direction of movement must be perpendicular to front and back.

Draw a line across the front of the artillery, the interpenetrating unit must pass from the front of the artillery directly to the back or back to front. The line of march would then be perpendicular to the line across the front of the artillery (90 degrees). This is the only allowed angle of interpenetration. Hope that helps.
