War of the Austrian Succession
Following the Treaty of Utrecht in 1713, the regiment was in garrison and on coastal watch duties in England and Ireland, until the War of the Austrian Succession erupted across the face of Europe. At the Battle of Dettingen on June 27th, 1743 the regiment participated with honor in the last battle in which a British monarch, George II led the troops. The Royal Welch defeated three French regiments including the famous Regiment of Navarre, and in commemoration of the King’s presence, were allowed the inclusion of the badge of the White Horse of Hanover to their colors. In 1745, the regiment was very badly mauled at the Battle of Fontenoy when the Duke of Cumberland foolishly attacked a very strongly fortified position. Although twice successful in breaking the French line, the position was untenable and with losses of 323 men, the regiment fell back.There was one further engagement in 1747 at Lauffeldt in which the again was defeated Duke of Cumberland the regiment was run down by its own cavalry and subsequently attacked by French infantry. Losses to the regiment stood at about 241 men, most of whom were prisoners.
