On the Western Front, the Germans were the first to arrive and dig trenches. They claimed the higher ground, giving them a tactical advantage as well as dryer trenches. They built deep bunkers, in reinforced concrete, equipped with running water and electricity. The British, on the other side, dug their trenches on lower ground which left them at risk for flooding and being constantly immersed in mud. The soldiers were in charge of digging and maintaining the trenches.
