The fifth, seventh, and eighth companies, second battalion, and detachments of the sixth and seventh companies, first battalion, were present at the siege of San Sebastian from the 11th July to the 8th September. The second company, second battalion, joined there on the 20th August from England, and was the first company in the corps that appeared in the scarlet uniform. All the men composing it had been instructed at Chatham, and were derisively styled “Pasley’s cadets.” The greatest number at the siege counted five Sub-Lieutenants—Gratton, Stratton, Turner, Wallace, and Johnson, and 305 non-commissioned officers and men. The eighth company, second battalion, with Lieutenant Turner, was posted on the Chofre hills, and the other companies on the isthmus. The men were divided into three reliefs; each relief was on duty eight hours, but when the works required to be pressed, the periods of rest were shortened to meet the emergency. The sub-lieutenants acted as assistant engineers. A large party of the corps did duty in the park, and the remainder were employed as overseers of the working parties. They also had to place the gabions, fascines, platforms, &c., open and repair the embrasures, and execute all services requiring more than ordinary skill, such as commencing the saps and leading their progress. In the early part of the siege the batteries and communications were wholly constructed by the sappers; but from the 16th July, these services, except in occasional instances of difficulty and danger, were performed by the line.

In both assaults parties of the corps assisted in carrying and placing the ladders for the stormers; others bore axes, crowbars, and intrenching tools. In the second assault it is recorded, that the party with picks and shovels “long persevered, with cool intrepidity, to form cover on the face of the breaches, but in vain.” The assault, however, ultimately succeeded. As well in the trenches as at the stormings, the sappers and miners distinguished themselves by their usefulness, intelligence, and gallantry.[[196]]

Here may be given a little incident to show how cool were the sappers in carrying on their duties. Colonel Pasley has stated that “several of the embrasures of the breaching battery were cut in broad daylight, under fire, by a party of the corps under Lieutenant E. Matson, R.E., after the guns in a part of the battery previously finished, had actually opened against the fortress.”[[197]]

Another instance is equally worthy of notice. “At one time,” according to Major Reid, “the trunk of a large poplar tree completely stopped the progress of the men and defied all their efforts to move it, until a daring sapper gallantly jumping from the trench, stood exposed until he moved it from the head of the sap, and returned without being wounded.”[[198]]

Striking instances of individual exploit follow, which are creditable to the soldiers whose names are associated with their performance. Sergeants William Powis and John Davis accompanied the first assault. Forced down the breach with the retreating stormers, they perceived Captain G. G. Lewis, R.E., lying badly wounded exposed to the enemy’s fire; and Davis, who but a few moments before had been wounded in the arm, returned with Powis to the breach and carried off their officer to the trenches. In effecting this gallant and humane act, Davis was a second time struck by a musket-ball, through which he lost an eye. By Major Pasley he was reported to be “a man of extraordinary merit and abilities, and a most skilful and ingenious artificer.”[[199]]

No less distinguished was private Hugh Borland at the second storming. In placing his ladders he discovered that they were likely to become useless, from the joints being insecure, and while in the act of binding the ends together with his braces—an act of supererogation which the service scarcely contemplated—a ball pierced the root of his tongue and killed him.

Santa Clara, a rocky island off St. Sebastian, had been taken, and it was necessary to communicate with the officer of engineers there on a matter of great importance. It being broad daylight, no boat could venture across the bay without the certainty of being sunk. Corporal Thomas Evans therefore volunteered to execute the service. He immediately stripped himself, tied his cap round his neck with the despatch in it, and plunging into the stream, performed, under fire from the castle, this gallant exploit unscathed. The distance to the island was nearly a mile, and he returned with an answer in about an hour.

The casualties at the siege were as follows:—

At the sortie—one killed; private James Hicks: three taken prisoners,[[200]] one of whom, private Owen Connor, was wounded.

In the trenches—four killed; second-corporals Findlay McDonald and Daniel Niblock, and privates Thomas Penhorwood and Peter Milne; Sub-Lieutenant Turner, wounded.
