Undaunted by these disasters, Gustavus refused to quit the field, although, for the present, he changed the theatre of war into Pomerania. From the wreck of the Protestant army, he carefully selected a chosen body of his favourite Scotsmen, which, in 1625, he constituted a regiment, conferring the command on Sir John Hepburn. In the war with Poland which ensued, the Scots enjoyed, as their gallant demeanour in every instance well merited, the unbounded confidence of the King. Subsequently, the King of Denmark sent two Scots regiments, which had been in his service, to aid the Swedish monarch; and, in 1628, he further received the very welcome reinforcement of 9000 Scots and English. The following incident, occurring about this time, serves to illustrate the cordial relationship subsisting between this renowned prince and our adventurous countrymen:—“In a partial action between the advance-guards, a few miles from Thorn, Gustavus’s hat was knocked off in a personal encounter with one of the enemy’s officers named Sirot, who afterwards wore the hat without knowing to whom it belonged. On the succeeding day, two prisoners (one a Scots officer named Hume) seeing Sirot wearing the King, their master’s, hat, wept exceedingly, and with exclamations of sorrow, desired to be informed if the King was dead. Sirot, being thus made acquainted with the quality of his antagonist in the preceding day’s skirmish, related the manner in which he became possessed of the hat, upon which they recovered a little from their anxiety and surprise.” The success of the Swedish arms at length achieved a favourable peace, which enabled the King, espousing the cause of the persecuted Reformers of Germany, once more to try the issues of war with the Imperialists, and so, if possible, redeem the disasters of a former campaign. At this period no fewer than 10,000 Scots and English exiles were in the Swedish army, and the King had just concluded a treaty with the Marquis of Hamilton, who had undertaken to enlist an additional force of 8000 in these Isles.
