Then, feeling his increasing weakness, he asked leave to return home, as "the work was done and the chain complete." But he died at sea, in sight of Plymouth Sound. His funeral in Westminster Abbey was a splendid one, worthy of the splendid service he had rendered to England, Cromwell having ordered that "no pomp was to be spared, so as to encourage all officers to venture their lives." A lasting shame it is indeed that at the Restoration his remains, with those of Deane, one of his admirals, and other Parliamentary officers, were taken from their graves, and buried without any mark of respect in one common grave in St. Margaret's Churchyard. Within the Abbey no monument marks his grave, though he had held for England the supremacy of the seas against vigorous attacks, and had made a reputation for himself "very wonderful, which will never be forgotten in Spain."

The very name of Prince Rupert breathes of romance and adventure. His mother was the fascinating and high-spirited Princess Elizabeth, daughter of James I., who had married Frederick, Prince Palatine of the Rhine, and had persuaded him to accept the crown of Bohemia when it was offered to him by the people, who had just wrested their independence from the Emperor of Austria. But his reign at Prague was short, for the Emperor won back his own, and the Queen of Hearts, as Elizabeth was affectionately called, had to escape with her children as best she could, Rupert being but a few weeks old. Her father, afraid of Spain and the Roman Catholic powers, would do nothing to help her, so she would have fared badly had it not been for some faithful English friends, headed by Lord Craven, and the people of Holland, who looked on the king of Bohemia as a sufferer in the Protestant cause, and who therefore gave his family a home besides a generous allowance. Frederick was not only deprived of his new kingdom, but lost also his old possessions, for the Emperor seized his lands on the Rhine and spoiled his palaces. Many a brave attempt he made to win back the Palatinate, always to be baffled, and at last, after the death of his eldest son, he fell into such a low state of health that he died of a fever. Elizabeth was left with three sons and two daughters, Rupert being her idol, for she believed him born to be a hero. And truly he was a boy to be proud of, excelling in everything he undertook, and such a true soldier that, when he was only fourteen, his tutors declared he was worthy to command a regiment. When Charles I. became king, he invited two of his nephews to England, and, with the queen, at once lost his heart to Rupert, who was then about eighteen. He proposed making him a bishop or marrying him to an heiress, but Rupert would hear of neither plan. A soldier's life, with plenty of adventure, was the only life for him.

On the 22nd of August in the year 1642, the Civil War broke out in England; the royal standard was set up at Nottingham, and Prince Rupert was made General of the Royal Horse, he being then but twenty-three. His very presence, brimming over as he was with enthusiasm, vigour, and determination, brought a breath of new life to the men who "could not hold back when the royal standard waved," yet "who did not like the quarrel, and heartily wished the king would yield and consent to what Parliament desired."

But Rupert was quite untouched by the general feeling of depression. The cause or its merits concerned him but little; he knew nothing of the intensity of the struggle, of the many unredressed grievances, of the arbitrary treatment of the nation's representatives in Parliament, of the total disregard for the opinions of the people which had at last made nothing but war possible between two such conflicting parties. He only saw the romantic side, a king called upon to defend himself in his own realm against rebels and traitors, and so heart and soul he espoused his uncle's cause. A cavalier of the cavaliers was Prince Rupert, with his handsome face, long flowing hair, clean-shaved cheeks, beplumed hat, and scarlet cloak, to which he added a very gallant bearing and a lordly manner. Directly he saw the cavalry he was to command, less than a thousand badly mounted untrained men, he dashed away like a whirlwind, to scour the country in search of more. Here, there, and everywhere he came and went like a flash, "in a short time heard of in many places at great distances," to quote a Parliamentary historian, till the very sound of his name had a magic effect. He charmed some, he terrified others, but he did what he would with them all, and in less than a month he rode back to join the court at Shrewsbury, with a picked force of three thousand men, well horsed and equipped. Contrasted with the indecision of Charles, Rupert's high-handed audacity was refreshing, and when the king left him free "to steer his own course," he at once set out for Worcester, which was threatened by Essex and the Parliamentary army.

The Royalist plan was to march on London, a plan which Parliament saw must at all costs be frustrated, so Essex received imperative orders to intercept and check the enemy. At Edgehill, near Banbury, the armies met, and the king, from his position on a hill-top, took view of Essex and his army in the vale.

"I shall give them battle," he said. "God assist the justice of my cause."

Then he called a council of war, at which many points of difference arose between the old soldiers and the young. Of course Rupert was the spokesman for the latter, and this was not the first time he had come into collision with the other generals of the Royalist army. Caution was a word unknown to him, and patience did not exist in his vocabulary. Slow and steady tactics he abhorred; he scorned the enemy, and pleaded vehemently for bold, dashing movements, which were, he said, best suited to the high-spirited soldiers of the king. As usual he prevailed, for he was never one who could be persuaded to change his opinion. His plan of battle was decided on, which meant that the Royal Horse should charge and drive the Roundhead Cavalry from the field, afterwards falling upon the flank of the enemy's infantry, while the Royalist infantry attacked them from the front.

"Then," he added, carried away by the thought of a victory which seemed so obvious, "the day is ours."

When the battle began in earnest Rupert charged with his cavalry, and so magnificently, that it seemed as if all his prophecies were fully justified, for the Roundheads were swept backwards till they broke and fled. But so excited and eager were the horsemen to pursue their flying foes, that they left all the Royalist infantry unprotected, and when Prince Rupert returned with such troops as he could rally from the chase, he found all confusion and uncertainty. Moreover, it was nearly dark, and no one was ready to support Rupert when he entreated that another charge might be made to settle the day. So, after all, it was only half a victory for the king's army, even though he held the road to London, while altogether quite 6000 Englishmen lay dead on the field.

Charles next made a move to Oxford, where he established his Court, for Oxford was almost the only city at that time "wholly devoted to his Majesty," and from here peace negotiations were again entered into, with the usual result that both sides were left still more bitterly opposed to each other. Rupert was charged with attacking two Parliamentary regiments at Brentford during the negotiations when all fighting was suspended. But with all his faults of impatience and impetuosity he was far too honourable a soldier to have willingly taken any unfair advantage of his foe, and it seems clear what he did was at the king's command, or when he was in ignorance of the stage which had been reached in the negotiations. While the king and the main army lay inactive though full of talk at Oxford, Rupert with his cavalry scoured the country round in search of men, horses, food, and forage, and indeed whatever they could lay hands on; for as Parliament held all the money, the king's soldiers had to live off the country as best they could, and wait patiently for pay which rarely came. The Prince, as was his wont, journeyed far and wide, his special object being to extend the king's territory all round Oxford and to take in all the west of England. So we hear of him, sometimes successful and sometimes baffled, at Cirencester, Banbury, Bristol, Gloucester, Birmingham, and Wales, then moving northwards in Leicester and Northamptonshire, till at the peremptory command of Charles he made his way towards York, which was in great danger, and which, "if lost," wrote the king, "would mean little less than the loss of the crown."
