SECTIONS OF THE HULL OF H.M.S. TERPSICHORE, SHOWING EFFECT OF THE TORPEDO EXPLOSION AT CHATHAM, 1865 CREATOR: UNKNOWN.
Sections of the hull of H.M.S. Terpsichore, showing effect of the torpedo explosion at Chatham, 1865. Official drawings '...by Mr. P. Thornton, Master Shipwright of Chatham Dockyard, showing the exact amount of damage that was inflicted upon the hull of the old 18-gun frigate Terpsichore by the explosion of the two 75-pounders [during] the very striking experiments with Mr. Beardslee's submarine torpedoes, or explosive shells...in the River Medway. No. 3 shows the relative positions of the ship, the torpedo, and the boat from which it was fired by an electric wire: the figure a representing the place where the boat lay when the torpedo was lowered from its side; while the figure b shows the place to which the boat had been removed before the signal of firing the torpedo was given...No. 1 shows the general longitudinal lines of the ship, with the hole made by the explosion of the torpedo...An enlarged view of a portion of the outside planking around this hole is also given. No. 2 presents a cross section of the vessel, showing very minutely how her timbers were shivered. In the parts marked a, the knees are seen as broken through the throat - viz., two on the starboard and four on the port side'. From "Illustrated London News", 1865. Sections of the hull of H.M.S.

EXPERIMENTS WITH TORPEDO-SHELLS AT CHATHAM: BLOWING-UP OF THE TERPSICHORE BY A 75-POUNDER, 1865. CREATOR: UNKNOWN.
Experiments with torpedo-shells at Chatham: blowing-up of the Terpsichore by a 75-pounder, 1865. 'Preparations were now made for destroying the Terpsichore, 18-gun sailing-frigate, which had been placed at the disposal of Mr. Beardslee by the Admiralty in order to put the destructive powers of the torpedo to the most practical test...a couple of 75-lb. torpedos were taken...close alongside the Terpsichore and there sunk...after a momentary pause, came the stifled report of both the torpedos at once, and the Terpsichore suddenly rose at her bows 10 ft. or 12 ft. into the air and heeled over on her starboard side, while great masses of water burst up through her decks, her whole frame being convulsed and heaving as with agony, till she began to settle down forwards. In another moment her stem stood up at an acute angle, and her bow sank deeper and deeper...The mischief she had received would seem to be a broken back; for she still continued to go down by the head, until, in about five minutes from her first movement, she lay fast aground in the Medway mud on an even keel, with the tide, now at three-quarters ebb, up to within a few inches of her portholes'.

EXPERIMENTS WITH TORPEDO-SHELLS AT CHATHAM: EXPLOSION OF A 440-POUNDER, 1865. CREATOR: UNKNOWN.
Experiments with torpedo-shells at Chatham: explosion of a 440-pounder, 1865. '...Mr. Donald M'Kay, the extensive shipowner, of Boston,...has undertaken to help in introducing the contrivance of Messrs. Wood and Beardslee to the Governments and public of Europe. Mr. Beardslee...had sunk a torpedo charged with 440 lb. of powder in the mud and sand off Gillingham Point, at the entrance to Chatham Harbour... A boat's crew was dispatched from the operator's barge to establish electrical communication with the sunken shell, which was to be fired through a length of two miles of wire. This preliminary completed and the train all ready for firing...in an instant there rose from the placid bosom of the river high into the air a huge column of water, in shape and action much resembling those great waterspouts occasionally witnessed by sailors in mid-ocean...The splendid volumes of snow-white feathery spray soared quickly to a height of little less than 200 ft., and then fell gently again in exquisitely graceful curves into the vortex whence they had risen, leaving no trace of themselves behind, save a slowly-expanding circle of bubbling, foaming water, the muddy, yeasty aspect of which showed that the river had been stirred to its lowest depths'.

THE AGINCOURT TARGET, EXPERIMENTED ON BY THE MACKAY GUN, 1864. CREATOR: UNKNOWN.
The Agincourt Target, experimented on by the Mackay Gun, 1864. Engraving from a photograph by Mr. J. Wilson of tests on '...the gun invented by Mr. James Mackay...and manufactured by the Mersey Steel and Ironworks Company. It has been tried at various ranges against a target similar to the sides of the iron-clad steamer Agincourt...[The] gun is of wrought iron, weighs nine tons, has a bore of 8'12 inches...The target consisted of an outer plate, 7 ft. square and 5½ in. thick, of rolled iron; next came 9 in. of teak, then an inner plate or skin three fourths of an inch thick, then angle iron and ribbing, and finally a backing up with timber balks and supports 18 in. thick. The plates, also made by the Mersey Steel and Iron Co., were the best that can be made of rolled iron... In the centre of the target was a 9-in, bull's-eye, and a centre ring about 3ft. in diameter. On the right upper corner of this centre the ball had penetrated about 2 ft. 5 in. from the right edge, and 6 in. from the bottom edge of the upper plate. There was a displacement...to the right, of about 2½ in.; and this, together with the fearful damage occasioned to the angle-iron, teak backing, and supports, rendered the target perfectly useless for further experiments'.

EXPERIMENTS WITH THE ARMSTRONG 600-POUNDER AGAINST THE WARRIOR FLOATING TARGET, 1864. CREATOR: UNKNOWN.
Experiments with the Armstrong 600-pounder against the Warrior floating target, 1864. 'The sight presented by the target when struck was very grand. The shell, from its enormous size, was distinctly seen throughout its flight of 1000 yards from the gun to the target, and as the shell exploded an immense volume of smoke and flame instantly enveloped the target. Above the smoke pieces of plank were seen flying in the air, announcing the demolition of the box in the rear...On taking the target to pieces the shattering effect was found to have extended far beyond the limits of the hole...The whole of [the] inclosing planks were torn off and blown away by the explosion of the shell. One of the massive timber struts was also tom away from the target by the blast, and another was broken laterally by the same cause. The Engraving shows the appearance of the target and the sea immediately around it at the moment the shell burst; the fragments of the wood inclosure were sent into the air, and portions of the shell and the splinters were hurled into the surrounding water. This sketch was taken from a point in front of the barracks at Shoeburyness, and from it may be readily gathered an idea of the deadly nature of this ponderous missile'.

EXPERIMENTS WITH THE ARMSTRONG 600-POUNDER AGAINST THE WARRIOR FLOATING TARGET, 1864. CREATOR: UNKNOWN.
Section of the Warrior floating target, showing the hole made by the 600-pound shell and the displacement of the upper plate, 1864. Diagram of '...a section through the target as it would appear if cut vertically through the centre of the hole made by the shell...the target was composed externally of armour plating 4½ in. thick, resting upon and bolted to a solid backing of teak 18 in. thick, which backing was again supported by an inner plating and framework representing the body of the ship...On taking the target to pieces the shattering effect was found to have extended far beyond the limits of the hole...Previous to the practice the timber supports at the back of the target were covered with planks strongly nailed to the timbers...The whole of these inclosing planks were torn off and blown away by the explosion of the shell. One of the massive timber struts was also tom away from the target by the blast, and another was broken laterally by the same cause. The shell appears to have exploded just as it entered the timber-backing, and it made a hole in the back of the target about four times as large as that in the front...The displacement of the armour plate and the damage to the timber backing is clearly shown in our Engraving'.
