This footage superimposes an epic World War I battle on the modern world

The Battle of the Somme was one of the bloodiest engagements in human history with over 1.5 million people wounded and killed from Jul. 1 to Nov. 18, 1916.

The British Army suffered its worst losses in a single day with over 57,000 casualties on Jul. 1.

The Allied Powers received little in exchange for all this blood, taking bits of German-held territory but falling short of their main objectives. The British were forced to rethink their tactics because of their stunning losses during the fight.

Now, 100 years after the battle ended, YouTube user MC C has released a video with classic Somme footage superimposed on the modern spots where the footage was originally filmed.

Check out the full video below. It's all gripping footage, but our favorite moments are at 18:02, one of the most massive explosions of the war; 27:12, a group of fusileers preparing for what would end up being their final attack; 31:05, artillery crews pounding German lines; and 36:30, a group of cheering soldiers marching together.
