Found in a British WW1 information site. www.firstworldwar.com/ Greatest Grenade Battle of the War Undoubtedly the greatest grenade battle of the war occurred on the Pozieres Heights on the night of 26-27 July 1916. Lasting for twelve-and-a-half hours without a break the Australians, with British support, exchanged grenades with their German foes (who threw multiple types of grenade: sticks, cricket balls, egg bombs and rifle grenades). The allied contingent alone threw some 15,000 Mills bombs during the night. Many grenadiers were killed that night, while many others simply fell down due to complete exhaustion In another part re grenades they wrote that the British soldier found it hard due to the tightness of his uniform to attache many grenades while the Australians with their looser fitting uniform could attache six or more to their uniform. The Brits quickly of course found other ways of carrying multiple grenades.
