Cold Lake Kid, SASS # 51474 Posted December 9, 2018 Share Posted December 9, 2018 I knew an old veteran, of the British Army, who described that weapon as a "Pom-Pom" It was used by the Boers in the Boer War. Link to comment Share on other sites More sharing options...

I believe this one shown is a Hotchkiss gun and not a Gatling. Gravity feed hopper and much slower than the Gatling. Seems I recall the Hotchkiss guns being used in the Spanish American war... but I've been wrong a time or two. Link to comment Share on other sites More sharing options...

Subdeacon Joe Posted December 9, 2018 Author Share Posted December 9, 2018 General information here: https://www.forgottenweapons.com/manual-machine-guns/hotchkiss-revolving-cannon/ Quote During testing by the US Ordnance Board in 1876 and 1877, a total of 1,136 rounds were fired from a 37mm (1.5″) gun with only 5 malfunctions of any kind. One projectile failed to explode on impact, which was found be to the result of a broken firing in in the fuse. The other four malfunctions were light strikes early in the testing – the firing pin spring in the cannon was found to be faulty and replaced. After that repair, no more problems were recorded. That is an impressive performance for a repeating cannon in 1876, and the Ordnance officers were rightfully impressed. They were also impressed with the manufacturing quality and mechanical design of the gun – particularly how the barrels are set in place and not rotating while loading and firing occurs (unlike the Gattling gun and other contemporaries). Primary use of the Hotchkiss revolving cannon was as navel armament, to defend large ships against smaller and much more agile torpedo boats. In this role, the Hotchkiss competed with other mechanical machine guns like the Nordenfelt and Gardner, but it was of a heavier caliber than the others. In addition to its original 37mm chambering, Hotchkiss cannons were also made in 47mm and 53mm in response to military demand. They were adopted by a number of nations including Brazil, France, China, the US, Holland, Greece, Chile, Argentina, Russia and Denmark. And from:http://www.victorianshipmodels.com/antitorpedoboatguns/Hotchkiss/hotchkissammunit.html Quote Case Shot Naval tactics in the 1880s were firmly based on close range encounters, indeed ramming had been seen at the principal means of destroying an enemy fleet following the battle of Lissa. Taking a ship by boarding was still a valid tactic, and weapons - cutlasses, pistols and rifles were provided throughout each warship for the crew to board or repel boarders. Every man on board had an assigned weapon for boarding. Therefore, there was a need for guns to be able to sweep away the mass of boarders at short range, as had been done from Trafalgar and before, by loading cannon with cases containing a large number of bullets. These could be fired from a Hotchkiss revolving cannon at a rate of up to 60 rounds per minute, and would provide devastating hail of lead at short range against anyone exposed on an opposing ship. The 37 mm case shot round was a thin drawn brass case filled with 28 hardened lead balls of 19 grams each. The 47mm and 53mm guns fired 30 and 58 balls respectively, each nearly 30 grams in weight. The balls were embedded in sawdust to stop them moving. In land service, however, the use of case shot was more important, to sweep away the massed ranks of troops at short ranges.
