In perhaps their most famous action, British and Canadian Fireflies defeated the heavy armour of a German counterattack at Saint-Aignan-de-Cramesnil during Operation Totalize on 8 August 1944, resulting in the destruction of five Tiger tanks and the death of the attack's leader, the noted German tank commander Michael Wittmann. The battle involved Fireflies from A Squadron, 1st Northamptonshire Yeomanry, 33rd Armoured Brigade; A Squadron, the Sherbrooke Fusiliers Regiment, 2nd Canadian Armoured Brigade and B Squadron, The 144th Regiment Royal Armoured Corps, 33rd Armoured Brigade. They ambushed a group of seven Tiger tanks from the 3rd Company and HQ Company, 101st SS Heavy Tank Battalion supported by Panzer IV tanks and StuG IV assault guns. The tanks of the 1st Northamptonshire Yeomanry reached the French village of Saint-Aignan-de-Cramesnil on the morning of 8 August 1944. While B Squadron stayed around the village, A and C Squadrons moved further south into a wood called Delle de la Roque. C Squadron positioned themselves on the east side of the woods and the under-strength A Squadron in the southern portion with No. 3 Troop on the western edge of the wood. From this position, they overlooked a large open section of ground and were able to watch as German tanks advanced up Route Nationale 158 from the town of Cintheaux. They held their fire until the German tanks were well within range. Ekins, the gunner of Sergeant Gordon's Sherman Firefly ("Velikye Luki" – A Squadron's tanks were named after towns in the Soviet Union) - had yet to fire his gun in action. With the Tigers in range a 12-minute battle commenced that saw Ekins destroy all three Tigers that No. 3 Troop could see. A short time later, the main German counterattack was made in the direction of C Squadron. A Squadron (less Sgt Gordon who had been wounded and had already bailed out of the Firefly) moved over to support them and in the resulting combat, Ekins destroyed a Panzer IV before his tank was hit and the crew were forced to bail out.
