 In all, the actions around Verrières Ridge during Operation Atlantic accounted for over 1,300 Allied casualties.Caen south of the Orne was captured, but the failure to seize Verrières Ridge led Montgomery to issue orders on 22 July for another offensive, this time to be a "holding attack", within a few days, in conjunction with Operation Cobra.As a result, Lieutenant-General Guy Simonds formulated the plans for Operation Spring.
