"Haida" continued the Operation Hostile sorties in company of sister ship "Huron" during the weeks leading up to Operation Overlord. The 10th Destroyer Flotilla were part of the covering force for surface attacks at the western entrance of the English Channel during the invasion of Normandy. On 8–9 June, "Haida" was part of Task Force 26 which engaged the German 8th Destroyer Flotilla, comprising "Z32", "Z24", and "T24" northwest of the Île de Bas. "Haida" and "Huron" combined to sink "Z32" in the Battle of Ushant. Following the fall of Cherboug, the German E-boats were transferred to Le Havre, freeing up the 10th Flotilla. The flotilla was then given the dual role of covering Allied motor torpedo boat flotillas and search and sink missions against German shipping along the French coast.
