context_page_description: Operation Atlantic was a Canadian offensive during the Battle of Normandy in the Second World War. The offensive, launched in conjunction with Operation Goodwood by the Second Army, was part of operations to seize the French city of Caen and vicinity from German forces. It was initially successful, with gains made on the flanks of the Orne River near Saint-André-sur-Orne but an attack by the 4th and 6th Canadian Infantry Brigades of the 2nd Canadian Infantry Division, against strongly defended German positions on Verrières Ridge to the south was a costly failure.
context_section_description: On 10 July General Bernard Montgomery, commander of all Allied ground forces in Normandy, held a meeting with Lieutenant-Generals Miles Dempsey and Omar Bradley, respectively the commanders of British Second Army and the United States First Army, at his headquarters to discuss the next attacks to be launched by 21st Army Group following the conclusion of Operation Charnwood and the failure of the First Army's initial breakout offensive. Montgomery approved Operation Cobra, a major break out attempt to be launched by the First Army on 18 July, and ordered Dempsey to "go on hitting: drawing the German strength, especially the armour, onto yourself - so as to ease the way for Brad[ley]".
  Detailed planning for Operation Goodwood began on Friday 14 July. On 15 July Montgomery issued a written order to Dempsey scaling back the operation. These new orders changed the operation from a "deep break-out to a limited attack". The intention of the operation was now "to engage the German armour in battle and "write it down" to such an extent that it is of no further value to the Germans", and to improve the Second Army's position. The orders stated that "a victory on the eastern flank will help us to gain what we want on the western flank" but warned that operations must not endanger Second Army's position, as it was a "firm bastion" that was needed for the success of American operations. It was stressed that II Canadian Corps' objectives were now vital, and only following their completion would VIII Corps be free to " "crack about" as the situation demands".
  Lt. Gen. Guy Simonds' II Canadian Corps would launch an attack, codenamed Operation Atlantic, on the western flank of VIII Corps to liberate Colombelles and the remaining portion of Caen south of the Orne river. Following the capture of these areas, the Corps was to be prepared to capture Verrières Ridge. The Atlantic–Goodwood operation was slated to commence on 18 July, two days before the planned start of Operation Cobra.
  Preparations for Atlantic were delegated to General Simonds, in his first action as the commander of II Canadian Corps. He planned the operation as a two-pronged assault, relying on the 2nd and 3rd Canadian Infantry Divisions to capture Vaucelles, Colombelles, and the opposite banks of the Orne River. On the morning of 18 July, Gen. Rod Keller's 3rd Division would cross the Orne near Colombelles, and then proceed south towards Route Nationale 158. The 3rd Division would then move to capture Cormelles. The 2nd Division, under the command of Gen. Charles Foulkes, would attack from Caen to the south-east, crossing the Orne to capture the outskirts of Vaucelles. They would then use Cormelles as a jumping-off point for an attack on the high ground near Verrières Ridge three miles to the south.
