During the winter the regiment marched to the vicinity of Stettin, the capital of Pomerania: it was subsequently employed in several operations; and in March, 1631, it was encamped at Schwedt, in the province of Brandenburg, where it was formed in brigade with three other Scots regiments, viz.--Mackay's, Lumsdell's, and Stargate's. This brigade was commanded by Colonel Hepburn, whose regiment took the right, and was designated HEPBURN'S SCOTS BRIGADE or the _Green Brigade_: other brigades were also formed and designated the _Yellow Brigade_, the _Blue Brigade_, and the _White Brigade_.[19] Advancing from Schwedt on the 24th of March, the regiment proceeded with the main army, commanded by Gustavus in person, to _Frankfort_ on the Oder, and was employed in the attack on the town. The army arrived before the town during the afternoon preceding Palm Sunday, and the regiment was posted opposite Gubengate. On the following day, after divine service had been twice performed, the King sent Captain Guntier of the regiment, with a serjeant and twelve private men, to ascertain if a body of troops could be lodged between the outer and inner walls; and this little party having, with fine courage, waded the ditch and ascended the mud wall, gained the required information, and returned without sustaining any loss; the King immediately afterwards commanded the town to be attacked by storm; HEPBURN'S SCOTS BRIGADE was ordered to commence the assault, and a select body of pikemen, with Sir John Hepburn at their head, took the lead in this splendid enterprise.
