| Notes | Another weapon that saw action in World Was One was the 8in howitzer. The Mk. I, II, III IV and V were adapted from naval guns which were heavy with only a short range. The Mk. VI, VII and VIII were completely different and came from a new design. The Mk. VIII saw action again in World with three batteries being sent to France with the BEF and those that remained were used to defend Britain. Many of these were converted into 7.2in Howitzers. |
