Hitting a unit through a wall

[Rogue]

This came up in my last game: can a unit engage in melee with an enemy unit on the other side of a solid wall? The wall in question is one of the older terrain pieces (with all the rectangular panels that glue together, and a small balcony), so the wall was properly solid, with no windows, and just one broken bit allowing a view of one model.

 

I had a unit of aberrants hard up against the wall inside the ruin, and my opponent wanted to charge in with a dreadknight. He chose not to fire on them, worried that if he did, I could remove the one aberrant by the broken bit, and potentially meaning that he couldn't then fight them. But is that right?

 

The charge rules specify that you can charge a unit you can't see. The charge is successful if you get within engagement range (1") - with a thin wall, and the aberrants pressed against it, a model on the other side of the wall is easily within 1". A dreadknight can't move through the wall, but in this case, it doesn't have to - in fact, it doesn't even have to touch the wall to get within 1".

 

And because the knight is within engagement range, it's eligible to fight. At no point do the rules refer to being able to see the target models, nor to having to be in direct combat.

 

In the end, he fired elsewhere, then charged the aberrants, and we concluded that even if he had killed the visible one, it was fine for the dreadknight to fight through the wall - it seemed plausible that a massive armoured fighting suit would simply punch holes in the wall to reach the aberrants on the other side.

 

But if we've missed something, please let me know what.
