On the 2nd of July, at three o'clock in the morning, the army marched in the direction of Donawerth, to attack a body of French and Bavarians under the Count d'Arco, in an entrenched camp on the heights of _Schellenberg_, on the left bank of the Danube. After traversing a difficult tract of country, the troops crossed the river Wernitz and arrived in front of the enemy's camp, and about six in the evening the leading division, consisting of a detachment from each British regiment, with the Foot Guards, ROYALS, and Ingoldsby's regiment (23rd), commanded by Brigadier-General Fergusson, and a Dutch force under General Goor, advanced under cover of a heavy cannonade, to attack the enemy's entrenchments. When these brave troops arrived within the range of the enemy's cannon they were assailed by a volley of grape, which produced a dreadful carnage. General Goor and many brave officers fell; Lieut.-Col. White of the ROYALS was severely wounded; yet the assailants moved forward with a firm tread until they arrived at a ravine which they were unable to pass, when they shrunk back before the shower of bullets which assailed them. At this moment the enemy issued from the entrenchments and charged the British and Dutch with great fury, but were gallantly opposed by the English Foot Guards. The ROYALS and Ingoldsby's regiment also confronted the charging Bavarians with firmness, and the enemy was repulsed and driven back into the entrenchments. A second attack was soon afterwards made on the heights, and the ROYALS were again sharply engaged. The French and Bavarians made a vigorous resistance, and sallying from the trenches attacked the leading regiments of the allies; the British and Dutch infantry being exhausted by a continued struggle up a rising ground, and their ranks thinned by a destructive fire, once more shrunk back; they were, however, supported by the cavalry under Lieut.-General Lumley, and having rallied, they returned to the attack with great resolution. This protracted contest shook the strength and weakened the resistance of the enemy. The Imperialists, commanded by the Margrave of Baden, arrived at the scene of conflict and attacked the enemy's left; at the same time the British and Dutch made another furious attack. Three field-officers of the ROYALS had already been carried from the field wounded, yet the regiment was seen pressing upon the enemy, and making a desperate effort to force the entrenchments; the Scots Greys dismounted to join in the attack; and the French and Bavarians were overpowered and driven from the heights with dreadful carnage. The cavalry under General Lumley charged the fugitives, and completed the overthrow of the enemy. Sixteen pieces of artillery, a number of standards and colours, with the enemy's tents, and the equipage, and the plate of Count d'Arco, fell into the hands of the confederates.
