In the beginning of the following year the other three troops of the regiment were withdrawn from Ireland, and after occupying quarters a short time at Northampton, embarked (4th April, 1704) for Holland. The six troops were thus united in time for the whole regiment to take part in the glorious exploits of the campaign of 1704, in which that noble ardour and chivalric spirit which has raised Britain to its present exalted station among the nations of Europe, were displayed by the army under the Duke of Marlborough in a signal manner. Confidence in the commander has always given additional life and vigour to innate valour, and the troops having already proved the military virtues of their leader, the great Marlborough was enabled to march his forces from the ocean to the Danube, and to gain new honours in the heart of Germany. This enterprise was undertaken in consequence of the armies of France and Bavaria having united against the Emperor of Germany, and the British general advanced to the aid of the house of Austria, which was thus menaced by a force which it was unable to withstand. Quitting the territory of the Dutch republic the army crossed the Rhine, and traversed the various states of Germany with a degree of order and regularity which bespoke a high state of discipline, united with excellent arrangements, while the nations of Europe gazed with astonishment at the undertaking. Having arrived at the theatre of war and joined the Imperial army, the first action of importance was the attack of a body of French and Bavarians commanded by the Count d'Arco, at their entrenched camp on the lofty heights of _Schellenberg_, on the 2d of July. On this occasion the cavalry supported the attacks of the infantry, and when the enemy was forced from the entrenchments, the brilliant charge of the English horse, and Royal Scots Dragoons (the Greys) completed the overthrow; the hostile army lost its colours, cannon, and baggage, and numbers of French and Bavarians fell beneath the conquering sabres of the British horsemen, who chased their adversaries to the banks of the Danube, and captured many prisoners. CADOGAN'S HORSE were commanded on this occasion by Lieutenant-Colonel George Kellum, and had Major Napier,[8] Lieutenant Tettefall, and several private men wounded; and sustained a serious loss in troop horses, from having been exposed to a heavy cannonade: their Colonel, Brigadier-General Cadogan, was also wounded.
