Sir W. G. Armstrong, the chairman and founder of this great firm of warship builders and makers of big guns at Elswick, Newcastle-on-Tyne, is the son of a Cumberland yeoman, and born at Newcastle in 1810. He early showed a turn for mechanical contrivances, and delicate youth as he was, when confined to the house he was quite happy making toys of old spinning-wheels and such-like things. He would also spend hours in a joiner's shop, copying the joiner's work, and making miniature engines. He had ample opportunity in his father's house of making himself acquainted with chemistry, electricity, and mechanics. In spite of his turn for mechanics, he was articled to a solicitor, who, at the finish of his apprenticeship, made him his partner. In his leisure hours he conducted his experiments. Fishing was also a favourite pastime with him, and in 1836, while rambling through Dent Dale, he saw a stream descending from a great height and driving only one single mill. This led him to think that there might be a more economical use of this water hydraulically, with the result that he produced a hydraulic engine, which was followed by the invention of a hydraulic crane for raising weights at harbours and in warehouses. It was soon adopted at the Albert Dock, Liverpool, and elsewhere.
Next he invented an apparatus for extracting electricity from steam, afterwards introduced into the Polytechnic Institution, London. Napoleon III. heard of this famous machine, and sent experts to examine it. Armstrong began to receive recognition; he was elected a member of the Royal Society in 1846, and a year later, aided by some friends, he began on a small scale the Elswick Engine-works in the suburbs of Newcastle, which have grown to be the largest concern of the kind in the country. At first the enterprise chiefly consisted in the manufacture of hydraulic cranes, engines, accumulators, and bridges.
The addition of ordnance and shipping, for which Armstrong became chiefly known, came later. Previous to the year 1853, the weapon used by the infantry portion of the British army was a clumsy smooth-bore musket, which was only effective up to three hundred yards at the farthest; the usual distance at which practice was made by the soldier seldom exceeding one hundred yards. In the above-named year, an arm was brought into use, termed, from the locality of its manufacture, the Enfield rifle. This weapon being lighter, and possessing a much greater range than the old small-arm, Brown Bess, as it was called, threatened very seriously to diminish the effect of field-artillery, if not to abolish that arm entirely, as, indeed, many infantry officers were sanguine enough to predict. Nor were they without good reason for their boasting, the only field-artillery consisting of 6-pounder brass guns for horse-artillery, 9-pounder guns for field-batteries, and sometimes 12-pounder and 18-pounder guns as batteries of position--that is to say, batteries used when the general of a force meant to make any stand in a suitable position; on these occasions, the guns were taken to the requisite places, and there left. Now, all these guns were smooth-bored; and as the range of the 6 and 9 pounders was limited in practice to about one thousand yards, it was a fair enough supposition that a company of concealed riflemen with their Enfield rifles could pick off the gunners and remain themselves comparatively secure, especially as their muskets being sighted up to, and effective at, eleven hundred yards, the guns also would be a good mark to aim at, and the riflemen hard to see, even if exposed.
