The Fourth Horse marched into the city of Liege on the 14th of October, where they remained until the 25th, when they were detached across the river to invest the Chartreuse; and, after the surrender of this place, they were employed in escorting the garrison towards Antwerp.[23] Having performed this service they went into village cantonments, and before the following spring the British commander was advanced to the dignity of Duke of Marlborough.

1703

Having passed the winter in Dutch Brabant, the Fourth Horse, moving from their quarters in May, 1703, traversed the country to the vicinity of Maestricht; at the same time one division of the army besieged and took Bonn. They were subsequently encamped near the banks of the Maese, where the Duke of Marlborough assembled the army; and on the 24th of May advanced against the enemy, who occupied an advantageous post near Tongres; but on the approach of the allies the French retired, and afterwards took post behind their fortified lines.

The Fourth Horse were subsequently encamped with the army near Haneff, where they were engaged in a slight skirmish with a detachment of the enemy. The Duke of Marlborough was desirous of attacking the French lines, but was prevented by the indecision of the Dutch generals and field-deputies. The Fourth Horse were also employed in the operations which preceded the investiture of Huy, and formed part of the covering army during the siege of that place. They were afterwards in the lines of circumvallation before Limburg; and after the surrender of this place they proceeded to Liege; and on the 4th of October joined the camp at St. Trond, where they halted a few days, and were subsequently distributed into cantonments.

1704

The British horse again passed the winter amongst the rude peasantry of Holland, and assembled with the army in the spring of 1704 near Ruremonde, from whence they directed their march to Cologne, and afterwards proceeded through a delightful country to Coblentz, a town situate at the conflux of the Rhine and Moselle. By these movements the Duke of Marlborough indicated a design of carrying on the war in the direction of the Moselle; but he had a more noble and hazardous object in view.

The Elector of Bavaria, who is presumed to have aspired to the imperial dignity, had commenced hostilities against the Emperor of Germany. In 1703, 30,000 French troops marched through the Black Forest to assist him, the united French and Bavarian armies were carrying all before them, and it was apprehended that if something extraordinary was not undertaken, the Elector of Bavaria would gain the imperial throne,—Germany would be subjected to French domination,—and Louis XIV. would dictate laws to Europe. To avert this disaster, the Duke of Marlborough resolved to march the army under his command from the Netherlands into the heart of Germany.

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.
