The old Scots Brigade, however, continued at its post of duty, and it formed part of the army, commanded by Marshal Horn and the Duke of Saxe-Weimar, which advanced to the relief of _Nordlingen_; and this movement brought on a general engagement, which was fought in the vicinity of the town on the 26th of August, 1634, when the confederates were defeated, and the Scots Brigade suffered so severely, that one of the regiments (Monro's) was reduced a few days afterwards to one company.[33] After the battle, the wreck of this distinguished brigade retreated to Worms, a town situate on the left bank of the Rhine; and, Marshal Horn having been taken prisoner, the veteran Scots were under the orders of the Duke of Saxe-Weimar. The loss of the battle of _Nordlingen_ almost ruined the protestant interest in Germany, but soon afterwards the court of France agreed to support this depressed and declining cause. The prospect of immediate succours from France allayed the consternation which prevailed amongst the confederate princes. A French army approached the Rhine, and several towns in Alsace admitted French garrisons. In the French army which thus approached the Rhine, the celebrated SIR JOHN HEPBURN appeared at the head of a Scots regiment in the French service. When this officer quitted Germany in 1632 (as before stated), he was not satisfied with the manner in which the Swedish affairs were conducted: on his arrival in England he was knighted; in the following year he tendered his services to Louis XIII.; and a regiment having been constituted of the old Scots companies and some newly-raised men, he was appointed its Colonel, by commission dated the 26th of January, 1633. He served in 1634 with the French army,[34] commanded by Marshal de la Force. During the summer he was engaged in the siege of _La Motte_ (or La Mothe), which place surrendered on the 26th of July; and HEPBURN'S REGIMENT lost one captain and several men in this service. On the 19th of December, Sir John Hepburn passed the Rhine with his own and six other regiments of infantry, seven cornets (or troops) of cavalry, and a train of artillery, and took post at Manheim, from whence he sent forward parties to reconnoitre the enemy. The remainder of the French army afterwards passed the Rhine, and Sir John Hepburn marched to the relief of _Heidelberg_, an ancient city situate on the river Neckar, at the foot of the mountain called the Giesberg. This city was besieged by the Imperialists, and defended by the Swedes. After some sharp fighting, in which Sir John Hepburn distinguished himself, the besieging army retreated, and the city was delivered to the French on the 23rd of December. [Sidenote: 1635]
