A brief campaign resulted in the capture of Rhynberg, which triumph Prince Henry celebrated with a tournament held at the Hague. On this occasion Rupert greatly distinguished himself, carrying off the palm, "with such a graceful air accompanying all his actions, as drew the hearts and eyes of all spectators towards him ... The ladies also contended among themselves which should crown him with the greatest and most welcome glory."[2] {21} After all this excitement, the boy found his life at Leyden irksome, and "his thoughts were so wholly taken up with the love of arms, that he had no great passion for any other study." He was therefore allowed to return to active service, and on the next campaign he served in the Stadtholder's Life Guards. With eager delight, he "delivered himself up to all the common duties and circumstances of a private soldier;"[3] in which capacity he witnessed the sieges of Louvain, Schenkenseyan, and the horrible sack of Tirlemont. Even thus early he showed something of the impatience and impetuosity which was afterwards his bane. The dilatory methods and cautious policy of the Stadtholder fretted him; "an active Prince, like ours, was always for charging the enemy." His courage indeed "astonished the eldest soldiers," and they exerted themselves to preserve from harm the young comrade who took no care of himself.[4] Eventually Rupert returned from his second campaign, covered with glory, and not a little spoilt by the petting of the Stadtholder, and of his companions in arms. A visit to England, which followed soon after, did not tend to lessen his good opinion of himself. His eldest brother, Charles Louis, had just attained his eighteenth year. This being the legal age for Princes of the Empire, he assumed his father's title of Prince Elector Palatine, and was thereupon summoned to England by his uncle, King Charles, who hoped to accomplish his restoration to the Palatinate. Elizabeth suffered the departure of her favourite with much misgiving. "He is young _et fort nouveau_, so as he will no doubt commit many errors," she wrote to Sir Henry Vane. "I fear damnably how he will do with your ladies, for he is a very ill courtier; therefore I pray you desire them not to laugh too much at him, but to be merciful to him."[5] {22}
