In pursuance of this object, the FOURTH HORSE, having crossed the Rhine and the Moselle, moved forward with the other cavalry regiments in advance of the main army, and commenced their march on an expedition which produced the most stupendous results. During the advance the regiments invariably moved from their camp ground at the first dawn of morning light, completed the march before the heat became oppressive, and passed the remainder of the day in repose, or in preparing for the succeeding day's march.[24] Continuing their route, under favourable circumstances and in excellent order, the British cavalry arrived towards the end of May at the suburbs of Mentz, in the west of Germany, where they halted a day to rest their horses. From this place they advanced in four days to Ladenburg, in the margraviate of Baden, and having passed the Neckar, halted one day at their camp beyond the town. From thence they directed their march towards the Danube; while the nations of Europe gazed with astonishment at this splendid enterprise, and the different states through which the troops passed hailed their arrival with acclamations. At length a junction was effected between the army of the Duke of Marlborough and the forces of the German empire, and the united troops co-operated in offensive measures. The FOURTH HORSE, having thus marched from the ocean to the Danube, took an active part in the operations which succeeded; and they formed part of the forces which advanced at three o'clock on the morning of the 2nd of July, and after traversing many miles of difficult country, arrived in front of the enemy's entrenched position on the heights of _Schellenberg_, and commenced the attack about six in the evening.
