. The need for additional airfields on the Normandy mainland ensured Carpiquet was a valuable prize for the Allies and a heavily-defended position for the Germans.

German defences

The German defences in and around Carpiquet were formidable, as the position was considered "strategically vital" by both sides. The defences at Carpiquet airfield relied on a 1.2 mi (1.9 km) expanse of level ground, which offered the perfect "killing field" for the defenders. The airfield had been converted into a defensive fortress, employing minefields, field gun

  would bombard German positions around Carpiquet, some 15 mi (24.1 km) inland.

Operation Windsor was designed to commence at 05:00 on 4 July—following a bombardment by 21 artillery regiments—with Le Régiment de la Chaudière and The North Shore Regiment attacking Carpiquet while the Sherbrooke Fusiliers protected their northern flank. To the south, The RWR would advance and seize the hangars of Carpiquet airfield. Once the two regiments had captured Carpiquet, the QWR would push through and take control of the airfield's control buildings. Its capture would enable further Anglo-Canadian attacks against Caen itself.

Canadian assault on Carpiquet, 4 July

As dawn broke on 4 July 1944, 21 artillery regiments opened fire on German positions in and around Carpiquet, laying down a creeping barrage 1 mi (1.6 km) wide and 400 yd (365.8 m) deep. At 05:00, two Canadian infantry regiments advanced on Carpiquet, while the Sherbrooke Fusiliers attacked to the north. The Sherbooke Fusiliers attack succeeded in breaking through the German minefields, but the defensive positions of the 26th SS Panzergrenadier Regiment remained intact and continued to fire on advancing infantry of The North Shore Regiment. In the centre, the Chaudières avoided much of the fire directed at The North Shore Regiment as they advanced on Carpiquet. By 06:32, both regiments had reached the outskirts of the town, coming into contact with elements of the 12th SS Panzer Division. As fighting in Carpiquet degenerated into a house-to-house battle of attrition, tanks of the Canadian 10th Armoured Regiment assisted the infantry in gradually overcoming German opposition.

To the south, the RWR advanced slowly towards the airfield, with German mortar fire inflicting heavy casualties on advancing infantry and armour alike. It would take the RWR 90 minutes to advance the 1.5 mi (2.4 km) between Marcelet and the airfield hangars. Only with eventual indirect fire support from an available squadron of the 10th Armoured Regiment was the RWR able to advance to the airfield. Several Sherman tanks were knocked out; by midday, the RWR were forced to withdraw halfway toward their original positions.

Unaware that the RWR had failed to gain control of the airfield, Keller elected to commit the QRC to the second phase of the assault plan. The regiment moved forward into Carpiquet—now controlled by the Chaudières and The North Shore who attacked German strongpoints bypassed by the initial assault. It took a combination of infantry attacks, flame-throwers, petard-tanks (Churchill tanks mounted with a 290 mm (11 in) spigot mortar), and the immolation of one strongpoint to force the remaining 12 defenders to surrender, with the remainder surrendering after vicious fighting. The QRC reached the edge of Carpiquet as the RWR was withdrawing, and was ordered to hold their positions until the RWR could reorganize for a second attack.

For the second attack on the airfield, Keller secured the assistance of two squadrons of Hawker Typhoon fighter-bombers to support the attacks against 12th SS positions. The survivors of the RWR were ordered to "execute a sweeping attack by the lower ground around the enemy's left flank", with full armour and artillery support. In the late afternoon, the RWR resumed the attack on the airfield. Although they reached the hangars, they were unable to dislodge the German defenders. Facing strong counter-attacks by Panzer units, the RWR was ordered to withdraw to their start-line under the cover of darkness. In Carpiquet, three battalions of the 8th Canadian Infantry Brigade rapidly fortified their positions. Following their seizure of the town, the 8th Brigade was now positioned closer to Caen than any other Anglo-Canadian unit. Although the Canadians had firm control of Carpiquet and the northern hangars, the southern hangars and control buildings remained in German hands.

German counterattacks, 5 July

Less than 1 miles (1.6 km) away from the outskirts of Caen, the 8th Canadian Infantry Brigade posed a significant threat to German positions in the town. With most of the defence concentrated north of Caen and by the River Odon, it was feared that Anglo-Canadian forces could attack from Carpiquet and bypass the majority of the defences. Despite growing misgivings about the success of a counterattack, Kurt Meyer, the German commander, ordered the soldiers of the 12th SS Panzer Division to retake Carpiquet from the Canadians. SS forces prepared to counterattack at Carpiquet from Francqueville with armour, artillery, mortars and infantry.

Shortly after midnight, the first of the SS counterattacks began, throwing itself against the Canadian defences. Although 13 tanks had been lost the previous day, the remainder of the 10th Canadian Armoured Regiment, supported by mortars from the Cameron Highlanders, prevented German panzers from penetrating the ruins of Carpiquet. Strong Canadian defensive positions and machine-gun fire caused heavy German casualties. By dawn, almost no ground had been gained by the attackers. By midday, the 8th Canadian Infantry Brigade and 10th Canadian Armoured Regiment had defeated three counterattacks with artillery and Hawker Typhoon assistance, ensuring that German forces could not breach the Canadian positions. The town remained under Canadian control, even though German Nebelwerfer Rocket-Artillery

Canadian casualties for the operation totaled 377, of which 127 were fatal. The majority of these losses occurred on 4 July— the RWR and The North Shore Regiment took approximately 130 casualties each on the first day. In total, 17 tanks were lost by the 10th Canadian Armoured Regiment, with an unknown number of losses by the Sherbrooke Fusiliers. Casualty statistics for the German defenders indicate 155 total losses, the majority of which occurred during the counter-attacks on 5 July.
