The regiment then saw its first action at the Battle of Haastembeck, where it was the first engaged, and took part in all subsequent battles during the Hanover Campaign. In early 1758, the regiment moved back across the Rhine, and was tasked with guarding the passes across the river. On 23 June 1758, the regiment was involved in the Battle of Krefeld, and in 1759 rose to great prominence during the Battle of Minden.
