1918: Battle of Belleau Wood

Deep in Belleau Wood, just outside of Paris, the Marine Corps fought relentlessly against German soldiers in World War I. Four days into battle, Marines had suffered heavy casualties and were pinned down by machine-gun fire. 
 
On 7 June 1918, with few grenades and no signal flares left, Marine forces launched an assault with fixed bayonets, seizing enemy positions. Marine riflemen demonstrated their firing skills, shredding the lines of an oncoming German counterattack. 
 
After 20 days of intense fighting, the Marines had won the Battle of Belleau Wood. The German survivors, exhausted and wounded, gave a fitting nickname to their relentless opponent: Teufelhunden, or “Devil Dogs.”
