Haunting Photos Bring The Great War Back To Life

This year marks the 100th anniversary of the start of World War I, the 4-year conflict that cost the lives of millions of soldiers and civilians from all parts of the world.

Starting in 1914, The Great War plunged Europe into darkness, turning parts of the continent into a swamp of death, destruction and misery. Soldiers died by the hundreds of thousands in kilometers-long trenches, bombardments leveled entire cities and towns and thousands were forced to flee their homes or battle hunger and poverty if they remained behind.

One hundred years after the beginning of the war, photographer Peter Macdiarmid revisited some of the key locations of the conflict. He overlaid his pictures with shots taken during the war years, bringing the haunting conflict of 1914 to 1918 back to life.
