In what war battle were tanks used for the first time?

Tanks were first used in combat during the First World War at the battle of the Somme, although the British Mark I tanks which participated were still experimental at the time.

armored vehicles were used before the somme. trucks with armour welded to them were used where the terrain would permit.

Although tanks were first used at the battle of the Somme, the first time they were used to gain a serious victory was at Cambrai, where British Mark IV tanks equipped with gap crossing bridges manages to smash the German front to pieces along a six-mile line.

One of the reasons the Germans lost WW1 was that they were reluctant to make their own tanks and when they did it was too late. At the end of the war, the British and French had over 6,000 tanks and the Germans had only 20!

This was all to change in the second world war when the British still used obselete tanks with guns that required them to get much closer to the German tanks than their German counterparts, which could simply fire at them while they closed in. It was not until tanks like the Sherman (Americans) and the T-34 (Russians) were used that the Allies armour got strong enough to rival the Germans.
