Did machine guns, gas and tanks break the World War I deadlock?

The first poison gas attack opened a gap in the line eight thousand yards wide, and the army that released it did not use it.

No: new weapons made the war deadlier, but not decisive. , poison gas and each changed the fighting, and none of them broke the deadlock on its own. The earlier years have been described as a clash of 20th-century technology with 19th-century military science, with huge numbers of casualties on both sides.

The machine gun came first, and it helped create the problem. Used in defence and combined with , converted the expected mobile battlefield into a static one. A machine gun could not move easily across a battlefield, so attackers had to face enemy machine guns without machine guns of their own.

Poison gas was meant to be the answer. The first killing gas was , used by the German Army; German chemical companies worked with the chemist Fritz Haber on ways of discharging it against enemy trenches. Chlorine was water-soluble, so covering the mouth and nose with a damp cloth reduced its effect. Estimates run up to about 90,000 gas fatalities and 1.3 million casualties, only 3 to 3.5 percent of the overall total, because such as gas masks could be developed. Still, the sight of an oncoming cloud was a continual source of dread for the infantry.

came last. They first appeared in 1916 and terrified some German troops, but early tanks were unreliable and broke down often. Only in the final year of the war did armies make effective steps in command, control and tactics to harness the new technologies.

Recap

Machine guns locked the front, gas and early tanks failed to open it, and only combined tactics learned late began to break the deadlock.

πŸ’‘ A trick to remember it Β· Think of a lock and three keys: the machine gun turned the lock, gas and tanks fumbled it, and it took a new way of turning to open it.

Surprising fact Β· At Amiens, only a few of 532 British tanks were still working after several days.
