Sir Charles was, as Arthur told Martin, a changed man from the period when his brother first knew him; and no one that had seen the grave, the manly, and thoughtful deportment of Sir Charles, the loyal and devoted officer, could have deemed it possible that he was the same person who had once invited and deserved their suspicions and their contempt. However, after lying nearly a month before Gloucester, and making little progress in the siege, the King was roused by the news that Essex was advancing to relieve the city. A last effort was decided on: the town had been most ably defended by Colonel Massey, the governor, who had made many bold and effective sallies, and interrupted the labours of the siege with good success; but the garrison was now reduced to great extremities for want of ammunition; therefore the King battered the town heavily for thirty-six hours, made a fair breach, and tried an open assault. The attempt was boldly made, and the breach mounted, but, after a bloody conflict, the storming-party was beaten back again. In this last affair Martin and Arthur were looking on at the assault, when a cannon bullet struck and shattered the leg of the latter, so that he was forced to have his limb amputated considerably above the knee,--a most painful operation, which he bore with a cheerful courage and composure. Thus did the service of this noble boy suddenly end, he being made a cripple for life, and no longer able to share the honourable toils of warfare or to partake ever again of the pleasant and joyous exercises natural to his age. The helplessness incident to the last season of life fell suddenly upon him, and made him prematurely old. Martin parted from him as he lay in hospital with tears in his eyes, and they never met again: however, Arthur was removed with other wounded to a place of safety, and when sufficiently recovered was sent to Oxford. Meantime the siege of Gloucester was raised; and, when Essex marched into that joyful town, he found them reduced to a single barrel of powder, and other provisions nearly exhausted. He stayed three days in the place, after which his care was to retire again to London without encountering the King’s army. He made a night march from Tewksbury to Cirencester, where he surprised two regiments of the royal horse, and found a great quantity of the King’s provisions; hence he made his route through the deep and enclosed country of North Wiltshire direct for London. However, Prince Rupert, with five thousand horse, by incredible diligence and forced marches, got between London and the enemy, and detained him till the King, with his main army, came to Newbury.
