Elizabeth had imagined that by sending her younger sons to school in Paris, she was keeping them out of harm's way; great was her surprise and annoyance when she found their position to be almost as dangerous as was that of Rupert. The cause of this new disaster was the imprudent conduct of the elder brother, Charles Louis. Undaunted by his recent defeat, the young Elector sought new means for recovering his country, and he now bethought him of Duke Bernhard of Saxe Weimar. The alliance of this Duke, a near neighbour of the Palatinate, was very important, and in January 1639 Lord Leicester had proposed a marriage between him and the Princess Elizabeth. Further, he had suggested to King Charles that Maurice should take a command in Bernhard's army, for which, young though the Prince was, he believed him fitted. "For," said he, "besides that he has a body well-made, strong, and able to endure hardships, he hath a mind that will not let it be idle if he can have employment. He is very temperate, of a grave and settled disposition, but would very fain be in action, which, with God's blessing, and his own endeavours will render him a brave man... Being once entered there, if Duke Bernhard should die, the army, in all likelihood would obey Prince Maurice; so keep itself from dissolving, and bring great advantage to the affairs of your nephew"[[1]] (i.e. to the Elector, Charles Louis).

But Charles Louis, full of impatience, and putting little faith in the negotiations of his uncle, set off in October 1639 to join Duke Bernhard in Alsace. Foolishly enough, he visited Paris, by the way, "en prince," and then attempted to depart thence incognito. Now it so happened that Cardinal Richelieu had uses of his own for the army of Duke Bernhard. It therefore suited him to detain the Elector in Paris, and the Elector's irregular conduct gave him the pretext he required. Declaring that so serious a breach of etiquette was capable of very sinister construction, he arrested Charles Louis, and placed his three brothers under restraint. Lord Leicester complained loudly of this treatment of the Elector, and though Maurice at once sent a servant to his brother, the man was only allowed to speak to Charles in French, and in the presence of his guards. The distracted mother flew to the Prince of Orange, who explained to her that Richelieu feared her son's attachment to England, which, however, Richelieu himself denied.

No sooner was the Weimarian army safely committed to the charge of a French general than Charles Louis was permitted to take up his residence with the English Ambassador. After this, though still a prisoner, he spent a very pleasant time in Paris, at an enormous expense to the King, his uncle. Maurice was allowed to return home in an English ship, but Edward and Philip were detained as hostages. Elizabeth spared no pains to recover them, and, as usual, made the Prince of Orange her excuse, "I send for Ned out of France, to be this summer in the army," she wrote to Roe; "and, finding Philip too young to learn any great matters yet, I send for him also, to return next winter;—which I assure you he shall not do."[[2]]

But it was not until April 1640 that her boys were restored to her, and the Elector did not recover his full liberty until the following July. In the autumn of the same year he went to England, to attend the marriage of his cousin Mary with the little William of Orange, on which occasion he quarrelled with the bridegroom for precedence. But his chief object in this visit was to obtain money either from King or Parliament. Elizabeth urged him to do something for Maurice, but he evidently regarded his third brother with much indifference. "As for my brother Maurice," he wrote, "your Majesty will be pleased to do with him as you think fit. It will be hard to get the money of his pension paid him."[[3]] His next letter was a little more encouraging. "The King says he will seek to get money for Maurice, and then he may go to what army he pleases. I want it very much myself, and it is very hard to come by in these times."[[4]]

The army which Maurice chose was that of the Swedes, under Banier; perhaps because it was then quartered near to the captive Rupert. Ere his departure, he wrote to King Charles:

"Sir,—Being ready to tacke a journy towards Generall Banier, I may not neglect to aquaint you therewithal, et to recomend myselfe et my actions to Yor Roial favour, whiche I chal strive to deserve in getting more capacity for your service. Yt is the greatest ambition of Yor Majestie's

"Most obedient nephew et humble servant,
"MAURICE."[[5]]

The letter, which is written in a clear, school-boy hand, betrays less confusion of tongues, the curious use of "et" notwithstanding, than do most epistles of the Palatines.

Maurice remained with the Swedes some months. In January 1641 his mother informed Roe that he was at Amberg in Bavaria. In the next month she was able to report of him at greater length. "I have had letters from Maurice, from Cham in the High Palatinate. He tells me that Banier has intercepted a letter of the Duke of Bavaria, to the Commander of Amberg. He writes that he understands that there is in Banier's army a young Palatine; and he should take good heed no bailiffs, or other officers, go to see him or hold any correspondence with him... Maurice is still very well used by Banier, who now makes more of Princes than heretofore, since he has married the Marquis of Baden's daughter."[[6]]

In June 1641 Maurice returned to Holland where he found life going on much as usual. Hunting and acting continued to be the principal Palatine amusements. "I did hunt a hare, last week, with my hounds; it took seven hours, the dogs never being at fault," wrote Elizabeth triumphantly; "I went out with forty horse at least, and there were but five at the death... Maurice, Prince Ravenville, the Archduke, and many another knight, were entreated by their horses to return on foot. I could not but tell you this adventure, for it is very famous here."[[7]] In another letter she tells how her daughters acted the play of "Medea and Jason", and how Louise, who played a man, looked "so like poor Rupert as you would then have justly called her by his name."[[8]] It is not unlikely that Louise impersonated Jason in her brother's clothes, and so enhanced the likeness.
