RAM (AS. rant, ramm, Ger. Ramme, batter ing-ram, 011G. ram, ramnio, Ger. Ram in, male sheep), MARINE. It was evident to the ancients that a ship. if given a sufficient rate of speed, could deal the enemy's vessel a more disastrous blow than could any weapon then known, so that the use of the rain is as ancient as maritime war. The oar-propelled galley furnished requi site speed and control for ramming, and to fur ther the efficacy of the craft of this sort they were furnished with beaks. The short ranges at which ancient weapons were dangerous were favorable to the use of the ram, and most of the celebrated actions of the galley were decided by it. But the advent of gunpowder rapidly effected a change. With the introduction of sail propul sion ramming wag nearly given over, but when steam came to the front it reappeared in a form which soon reached its highest development. The ram, however, has never aecomplished much ex cept under special conditions, and it is now re garded as a very subordinate weapon in naval warfare. W. Laird Clowes has carefully tabulated all the cases of ramming or attempted ramming which have taken place in modern naval warfare, and he finds that,: (a) when both vessels have had plenty of sea room and were able to steer not one of the thirty-two attempts to rim were wholly suecessful—indeed, the ships attempting to ram received slightly the gravest injuries: (b) where the ramming took place in waters which were too contracted to admit of free manceuvring (32 cases also), 28 per cent. of the vessels attacked by ramming were sunk, as were 3 per cent. of the attacking ships, while the percentages of the attacked vessels which were seriously injured was about double that of the ships attempting to ram. The torpedo and the greatly enhanced gun power of recently built ships both serve to weaken the influence of the ram upon naval operations, leaving its probable effective use confined to unusual and special con ditions.
It is difficult to determine who first suggested ramming by steam vessels. One of the earliest designs is that of Capt. Samuel Barron of the united States Navy, which was made in 1827 and a model of which is preserved at the Naval Academy. Annapolis. At this time, however,
there was hut one steam man-of-war in exist ence, and it was not until the Civil War broke out that attention was seriously attracted to the importance of ramming. The Merrimac was fitted with a ram with which she sank the Cum berland, and the Monitor was designed to use her sharp bow for ramming if opportunity offered. After the sinking of the Gumberland many War were supplied with rams, and at present nearly all fighting ships are so fitted, but it is not expected that the use of the ram will be other than exceptional.
The marine ram as a special vessel designed to use its beak as its principal weapon of offense appears to have had few advocates after the time of Captain Barron's ram in 1827 until late in the Civil War. Admiral Ammen of the United States Navy was a strong advocate of the purely rain type of vessel, and one of his designs was embodied in the U. S. S. Katandin. About 1880 the British built the torpedo ram Polyphemus; which is like the Katuhdin in many respects. No other large ram vessels have been built which are not also well armed with guns.
Among naval officers the use of the ram is now regarded as the last resort—a weak ship en deavors to sacrifice herself in destroying a more powerful one a ship whose battery is disabled attempts to destroy a still powerful enemy; or a ship which refuses to surrender is given the coup-de-grlice. In all this, however, the danger of the torpedo is to be faced, and that is com monly regarded as more to be feared than the ram.
