One question that occurs to anyone interested in the naval war is why the otherwise forward-looking Confederate Navy did not try to use breech loading cannon? There seem to be two answers: 1) the British were not interested in having advanced ordnance sold to foreign powers, and 2) by the middle of the war, a very public demonstration of the limits of current technology with breech loaders appeared when the Royal Navy opened fire in mid-1863 on the Japanese fortifications at Kagoshima. This was the first battle test of the infamous Armstrong guns. Intended to become the main armament of the heavier British warships, there were 28 accidents including bursting from only 21 guns firing a total of 365 rounds. The British "went back to muzzle-loaders for fifteen years". In one case at Kagoshima, "the Euryalus's forward 7-inch gun blew out its breech-block and concussed the whole (gun)crew..." ref: Preston & Major, Send a Gunboat, Revised Edition, Conway via Anova Books Ltd, London, 2007, pp 54-55. Although small rifled breech loaders were tried on a limited scale by the Confederate Army, (Hughes and Whitworth), there appears to be no record of an attempt to mount either type on a vessel. The Whitworth breech-loaders look as though they might have been adaptable for Naval use. They also had the advantage of being used as a muzzle-loader if the breech mechanism was damaged. The unique Hughes mini-cannon were produced in a very limited quantity (50 or less) and fired a very small round. They did have a rapid reload rate and good accuracy, suggesting that they might have made an excellent anti-personnel secondary armament aboard river gunboats or rams for suppressing Union snipers.
