Operation Goodwood was a Second World War British offensive that took place between 18 and 20 July 1944 as part of the ongoing battle for Caen in Normandy, France. British VIII Corps, with three armoured divisions, launched the attack aiming to seize the German-held Bourguébus Ridge, along with the area between Bretteville-sur-Laize and Vimont, while also destroying as many German tanks as possible. Goodwood was preceded by preliminary attacks dubbed the Second Battle of the Odon. On 18 July, British I Corps conducted an advance to secure a series of villages and the eastern flank of VIII Corps. On VIII Corps's western flank, Canadian II Corps launched a coordinated attack—codenamed Operation Atlantic—aimed at capturing the remaining German-held sections of the city of Caen south of the Orne River.When Operation Goodwood ended on 20 July, the armoured divisions had broken through the initial German defences and had advanced seven miles before coming to a halt in front of the Bourguébus Ridge, with armoured cars having penetrated even further south and over the ridge. The objective of the operation was a limited attack to secure Caen and the Bourguébus Ridge beyond, pinning German formations in the eastern region of the Normandy beachhead. This prevented German forces disengaging and moving south to confront US forces in their breakout operation, Operation Cobra, which began on 25 July. At least one historian has called the operation the largest tank battle that the British Army has ever fought.
