World War I in Photos: The Western Front, Part I
http://www.theatlantic.com/static/infocus/wwi/westernfront1/When we think of World War I, images of the bloody, muddy Western Front are generally what come to mind. Scenes of frightened young men standing in knee-deep mud, awaiting the call to go "over the top", facing machine guns, barbed wire, mortars, bayonets, hand-to-hand battles, and more. We also think of the frustrations of all involved: the seemingly simple goal, the incomprehensible difficulty of just moving forward, and the staggering numbers of men killed. The stalemate on the Western Front lasted for four years, forcing the advancement of new technologies, bleeding the resources of the belligerent nations, and destroying the surrounding countryside. Today's entry is part 2 of a 10-part series on World War I, which will be posted every Sunday until June 29. This installment focuses on the early years on the front, part II will focus more on the final year of trench warfare.

Looking out across a battlefield from an Anzac pill box near the Belgian city of Ypres in West Flanders in 1917. When German forces met stiff resistance in northern France in 1914, a "race to the sea" developed as France and Germany tried to outflank each other, establishing battle lines that stretched from Switzerland to the North Sea. Allies and Central Powers literally dug in, excavating thousands of miles of defensive trenches, and trying desperately to break through the other side for years, at unspeakably huge cost in blood and treasure.

Six German soldiers pose in a in trench with machine gun, a mere 40 meters from the British line, according to the caption provided. The machine gun appears to be a Maschinengewehr 08, or MG 08, capable of firing 450-500 rounds a minute. The large cylinder is a jacket around the barrel, filled with water to cool the metal during rapid fire. The soldier at right, with gas mask canister slung over his shoulder, is peering into a periscope to get a view of enemy activity. The soldier at rear, with steel helmet, holds a "potato masher" model 24 grenade. (Library of Congress) #

German captive balloon at Equancourt, France, on September 22, 1916. Observation balloons were used by both sides to gain an advantage of height across relatively flat terrain. Observers were lifted in a small gondola suspended below the hydrogen-filled balloons. Hundreds were shot down during the course of the war. (CC BY SA Benjamin Hirschfeld) #

Soldiers struggle to pull a huge piece of artillery through mud. The gun has been placed on a track created for a light railway. The soldiers are pushing a device, attached to the gun, that possibly slots into the tracks. Some of the men are in a ditch that runs alongside the track, the rest are on the track itself. A makeshift caterpillar tread has been fitted to the wheels of the gun, in an attempt to aid its movement through the mud. (National Library of Scotland) #

Dead horses are buried in a trench after the Battle of Haelen which was fought by the German and Belgian armies on August 12, 1914 near Haelen, Belgium. Horses were everywhere in World War I, used by armies, and caught up in farm fields turned into battlefields, millions of them were killed. (Library of Congress) #
