In 1664 we find in Pepys' Diary that Rupert had been "sent to command the Guinny Fleet. Few pleased, as he is accounted an unhappy [_i.e._, unlucky] man." As a consequence of these sentiments, which Rupert was soon destined by his valour to alter, one Captain Holmes was sent instead. Nevertheless it was known at Court that Rupert desired a naval employment, and as the authorities found that their estimate of his abilities was not mistaken, he was in 1666 selected to command the fleet against the Dutch, in conjunction with the Duke of Albemarle. His conduct was most exemplary. On one occasion he wrested a victory from the Dutch, and again in the month of June beat them soundly, pursuing them into their own harbour. Returning to England on the cessation of hostilities, he found himself in much higher favour at Court. But with a single exception, which I will proceed to relate, Rupert sought no favours at the hands of his royal relations from this moment until the day of his death. He was content to pursue an even career in comparative solitude, a circumstance for which a serious physical ailment, which soon overtook and for a time threatened his life, was no doubt in some measure responsible. The fire which distinguished his youth was exchanged, we are told, for good temper and sedateness. He was credited with writing an autobiography, but if the report be true, it is a pity there remains no tangible evidence of such an intention. It is certain that his correspondence was so large as to entail the continuous employment of a secretary, William Strong; but prior to the inception of the Hudson's Bay project, it probably related almost entirely to his chemical and scientific researches and achievements. In May, 1667, the Prince's secretary opened a letter from Lord Preston, then English ambassador at Paris, intimating that one M. des Groseilliers, a Canadian fur-trader, would be the bearer of an introductory letter from himself to his highness. He was convinced that the French were managing the fur-trade of New France very clumsily, and he added that Monsieur des Groseilliers seemed as much disaffected towards the new company lately chartered by the French king as towards the old. There is no reason, in the writer's opinion, why English men of commerce should not avail themselves of opportunities and instruments, such as the weak policy of their rivals now afforded, for obtaining a share in the northern fur-trade.
