10. Battle of Cambrai, 20 November â€“ 8 December 1917 World War Oneâ€™s Battle of Cambrai, fought between the British and the Germans, took place towards the end of 1917 and is often mistakenly called the first tank battle in history. In fact, the distinction of having taken part in the first ever tank battle goes to the French army, who deployed tanks earlier in 1917, as did the British at the Third Battle of Ypres. Cambrai did, however, see a larger number of tanks deployed than ever before. The British plan of attack was to use their tanks to strike at the heart of the German Hindenburg Line. This formidable defense was previously viewed as impenetrable, until a commander named Henry Hugh Tudor suggested using tanks to support the troops attempting to break through the line. Around 476 tanks were used and both sides lost around 45,000 men. The final result of the battle was an operational stalemate. 9. Second Battle of El Alamein, 23 October â€“ 11 November 1942 With over 1,000 Allied tanks lining up against their 547 Axis counterparts, World War Twoâ€™s Second Battle of El Alamein saw the Germans effectively lose their battle for possession of Egypt and the much-prized Suez Canal. After the First Battle of El Alamein had halted the Axis advance into Egypt, the second battle effectively turned the course of the North African Campaign in the Allied forcesâ€™ favor. Tanks played a huge part in the battle, with the Allied forces receiving Sherman Tanks courtesy of the Americans. This bolstered their forces and made it possible for them to continue with the conflict longer than the Germans, whose own forces were more concentrated on the Eastern Front.
