This was a very hard-fighting regiment and according to Kronoskaf: “In 1757, the regiment took part to the invasion of Bohemia. On May 6 1757, it was at the Battle of Prague where it was deployed in the first line in Hautcharmoy's Brigade. It suffered heavily in this battle, losing about 33% of its total strength. On September 7, when an Austrian force under the command of General Nádasdy attacked Winterfeldt's isolated corps in the Combat of Moys, the regiment was deployed in the first line of the centre under Major-Generals Wied and Kannacher. On November 22, the regiment took part in the Battle of Breslau where it was deployed in Prince Carl von Bevern's Brigade, in the first line of the infantry centre. It lost 3 officers and 474 men in this battle. After the surrender of Breslau, the remnants of the regiment dispersed.”
Of course the regiment was re-raised and then it lost a further 431 men in the Battle of Kunnersdorf.
