Gibbet Rath-massakren i Irland

Jacob Smith Jarmann ble født
Jacob Smith Jarmann ble født i Nord-Fron i Gudbrandsdalen. Jarmann er best kjent som konstruktør av Jarmann-geværet. Opprinnelig tenkte han å slå inn på en militær løpebane og gikk opp til offiserseksamen i 1840, men fikk imidlertid så dårlig karakter i tysk at han oppgav dette.

Omkring 1838 skal Jarmann ha konstruert et enkeltskudd bakladningsgevær for enhetspatroner i papp, som på tross av rosende omtale aldri ble innført i armeen, fordi det hadde en skuddhastighet på 13 skudd i minuttet og dermed et for den tid enormt ammunisjonsbehov. Dette gjorde at Jarmann la geværkonstruksjonene bort en periode.

Jarmann anla i 1854 Nylands Verksted og ledet det til 1878. Verkstedet bygde dampskip og maskiner til teknisk bruk. Men direktør Jarmann arbeidet i ledige stunder også med geværkonstruksjoner. 1870 hadde han ferdig en enkeltlader, forløperen til et 10,15 mm repetergevær med 8 patroner i et langsgående rørmagasin i skjeftet. Dette geværet ble etter mange inngående prøver med datidens beste europeiske og amerikanske geværmodeller antatt som armégevær i Norge ved kgl. resolusjon av 28. mars 1881. Jarmann fikk 24 000 kroner for arbeidet, og hans navn ble kjent over hele landet og ikke minst i utlandet. For sine geværkonstruksjoner ble Jarmann dessuten utnevnt til ridder av St. Olavs Orden 1881 og av den svenske Vasaorden.

Gibbet Rath-massakren i Irland
Mellom 300 og 500 ubevæpnede irske opprørere ble massakrert av britiske soldater ved Gibbet Rath etter at de hadde overgitt seg mot et løfte om amnesti.

Det irske opprøret i 1798 var et opprør mot det britiske styret på Irland. Det varte i flere måneder. Hovedorganisatoren var United Irishmen, en republikansk og revolusjonær organisasjon, som var påvirket av idealer fra den amerikanske og den franske revolusjon. Det er også kjent som «Wolfe Tone-opprøret» etter en av de fremste lederne, Theobald Wolfe Tone.

      Portrait of an original Remington percussion revolver

    • Portrait of an original Remington percussion revolver

      June, 1863: As the American Civil War raged on, a newly made percussion revolver passed the gates of the E. Remington & Sons factory in the small city of Ilion, New York. Exactly 150 years after the old veteran became mine. Now it was time to bring it back to life.

    Kammerlader

    Model 1860 Army kammerlader, converted to metallic cartridge after Lund's system some time after 1867.

    The 18 bore kammerlader rifles were continuously improved from the time the first model was adopted in 1842. In 1860 a new model was adopted. This model had several radical changes: The most important being the reduction of the calibre from 18 bore to 4''' (linjer, an old Norwegian measuring unit). Since roundballs were no longer used it served no purpose to designate the calibre in bullets per pound. 4''' equals 11.77 mm, and compared to the 18 bore rifles the calibre was reduced with 5 mm. The internals of the barrel were also changed. While the 18 bore kammerlader rifles had Krupp rifling the Model 1860 had hexagonal Whithworth rilfing. Another new feature was rifled chambers. The 4''' kammerlader is a lighter and slender firearm compared to the old models.

    Both civilian and military 4''' kammerlader rifles. Civilian kammerlader rifles for the shooting societies were made from parts that were intended for the military rifles. The shooting society kammerlader rifles are distinguished by the steel buttplate and barrel bands. The Army versions had brass bands and buttplate.

    Kammerlader

    Landmark conversion.

    The new kammerlader rifles had a short active service, and were soon converted to fire metallic cartridges. When the metallic cartridge was adopted along with the Remington rolling block rifle in 1867, most of the Model 1860 kammerlader rifles were converted to the new calibre. Two conversion systems were used. The Army used the system of Jacob Lund and the Navy relied on the system of Jens Landmark. The conversions are called Lund's rifles and Landmark's rifles. The new calibre was decided to be 12.17 mm, and the new cartridge got the official designation '12 mm Remington' (also known as 12.17x44, 12x42, 12.17x42, 12.7x44 and similar). You can read more about this cartridge in the article about the Remington rolling block.

    Models

    The following 4''' models are known:

    • M/1860 4''' Army three bander (long)
    • M/1860 4''' Army two bander (short)
    • M/1860 4''' three bander (long) for shooting societies
    • M/1860 4''' two bander (short) for shooting societies
    • M/1860 4''' Navy two bander
    • M/1862 4''' artillery carbine
    • M/1865 4''' cavalry carbine

    Lund's conversion. Notice the
    rimfire breech block.

    Today it is extremely rare to find an unconverted 4''' kammerlader rifle. If you find one, it is probably one of the shooting society models. The 4''' kammerlader rifles were very accurate in it time, and they performed very well in a comparativ shooting competition in Belgium in 1861.

    Bayonets

    The short Model 1860 kammerlader rifles were equipped with yataghan style sabre bayonets similar to that of the Remington rifle. It was also basically similar to the 18 bore short rifle bayonet. The long rifles was fitted with a socket bayonet.
