Catapults were used in some numbers during the Gallipoli campaign. The engineers of the Royal Navy Division’s 2nd company built a number catapults along the lines of the Leach - Gammage’s The Royal Marine Cyclist Company provided specialist support for the use of catapults and they were used in support of British troops such as the Bedfordshire Regiment. (One has to wonder just what a Cyclist Company was supposed to be doing in the confined area of Gallipoli.) In October 1915 the Australian forces were also issued with catapults, these are described as consisting of a triangular frame with a sling which was made of india rubber bands. The sling fired a cricket ball bomb and had a range up to 120 yards. It is not clear if these were the same as those built by the Royal Navy Division’s engineers or another example of parallel military evolution (this latter is quite possible for there were other examples of this at Gallipoli, the Royal Navy Division had produced a periscope rifle at about the same time as the Australians). Both British and Australian troops became very efficient in their use. The Turks soon began to use catapults themselves particularly against the Australian position known as Quinn’s Post, however they appear to have been very inaccurate. When the time came to evacuate the peninsula catapults were used to give the impression that the positions were still manned, time fuses were used to release bombs at intervals from a number of catapults left in the trenches.
For your gaming information.
