The front line of WWI was a dangerous place. From bullets to bombs to poison gas, the death that could be dealt on the battlefield came from many directions.
Mother nature included.
Excessive rains made mobility difficult as troops were forced to navigate through the mud-choked battlefields, making resupply and transport nearly impossible. With both sides bogged down, tanks were thought to enable a breakthrough, but they too soon succumbed to the clutches of mud.
Known as "Mark 1," the first tank was constructed with 105hp Daimler engine and carried two Hotchkiss six-pound (57mm) guns. The crew consisted four gunners and three drivers, and the tank maneuvered on caterpillar tracks with separate gearboxes.
Soldiers had to endure intense heat in the crew compartment, extreme noise and would sometimes be trapped for days if the tank got stuck.
After multiple design failures, the British considered canceling their tank program, but supporters kept them in the Empire's arsenal.
New tactics breathed new life into the lumbering beasts, focusing them into mass attacks that took advantage of proper terrain.
