While the Americans headed for Cherbourg, a unit of troops led by the British moved towards Caen. Montgomery made many attrition warfare attacks. The first was Operation Perch, which moved south from Bayeux to Villers-Bocage where the armour could capture Caen. It was halted at the Battle of Villers-Bocage. Caen was bombed and then occupied north of the River Orne in Operation Charnwood from 7 July until 9 July. An attack in the Caen area followed with all three British armoured divisions, codenamed "Operation Goodwood" from 18 July until 21 July. It captured the high ground south of Caen. The rest of the city was captured by Canadian forces during Operation Atlantic. A further operation, Operation Spring, from 25 July until 28 July, by the Canadians secured limited land south of the city, but with many dead and wounded.
