Cannon Hits
URL Copied!

The following is an excerpt from page 20 of the Warhammer Annual 2002 release with an expanded explanation by Gav Thorpe regarding how to resolve cannon hits.

The cannon rules on page 122 of the Warhammer rulebook contains the line, "When a cannonball collides through a unit, only one model per rank is hit". This has, understandably, caused some players to think that a unit hit in the flank by a cannon (enfilading fire, for you word buffs) will only ever lose one model out of a rank (see diagram 5).

Diagram 5 - Wrong! One model hit per rank. 3 models struck by the cannon ball.

Actually, the rule is written that way because the imaginary line that traces the course of the cannonball is infinitely thin, and therefore cannot pass between two models and affect them both (see diagram 6).

Diagram 6 - Right! One model hit per rank, 5 models struck by the cannon ball.

You should consider a unit that is hit in the flanks by a cannon (or a bolt thrower, for that matter) to have a number of ranks equal to its width. This means that if the shot passes along a rank, it can affect more than one model (see diagram 7).

Diagram 7 - If crew A fired its cannon at the flank of the unit of Orcs it could cause 5 possible hits. However, if crew B fired its cannon at the front of the Orc unit it could only cause 4 possible hits.

Sometimes a cannon ball may bounce through intervening terrain which the players think should probably stop it. When discussing the terrain before the battle commences, it is worth bearing in mind if any pieces of scenery will stop a cannon ball passing through. As ever, the diversity of terrain which people may have makes a hard and fast list impossible, but cliffs and very steep slopes, buildings, ruins and the like may well stop a cannon ball in its tracks, although the majority of terrain (including woods, obstacles and such) should not (see diagram 8).

Diagram 8 - A) If the cannon ball bounces before the cliff face it stops when it collides with the cliff. B) If the cannon ball lands on top of the cliff it bounces as normal and smashes into the unit of Goblins.
