During the 1940 North Africa campaign, the British Matilda II tanks were instrumental in defeating Italian forces due to their superior armor protection. As part of the 7th Royal Tank Regiment, these 50 heavily armored vehicles proved largely impervious to the majority of the enemy's antitank weapons.1

This technological advantage allowed British forces under Maj. Gen. Richard Nugent O’Connor to overcome significant numerical disadvantages. The Matilda IIs were particularly effective during the assault on the fortress of Bardia in January 1941, where 22 of the tanks led the way, causing the Italian defense to collapse rapidly and resulting in the surrender of the entire garrison. By neutralizing the effectiveness of Italian defensive weaponry, these tanks enabled the British to secure decisive victories, capture thousands of prisoners, and seize large quantities of enemy equipment throughout the early stages of the conflict in Cyrenaica.12
