In April 1942 "Queen Emma" was selected to take part in a raid on the French coast at Dieppe. On the evening of 18 August 1942 a fleet of more than 200 ships sailed across the Channel. "Queen Emma" and the former Belgian ship "Princess Astrid" landed men of the Royal Regiment of Canada on "Blue Beach" to the east of Dieppe at Puys. However, the raid was not a success, and the losses were high.
