What happened

From 19 September to mid-December 1944, American and German forces fought through the Hurtgen Forest, a dense, 50-square-mile woodland straddling the Belgian-German border, in what the US National Park Service calls the longest single battle ever fought by the US Army and the deadliest forest engagement of the war. The terrain worked against every American advantage: thick tree canopy blocked aerial spotting and limited artillery observation, steep muddy valleys funneled tanks onto a handful of narrow trails, and German defenders had used a long lull in the fighting to seed the ground heavily with mines. Artillery shells bursting in the treetops showered troops below with shrapnel and splintered wood, and the 4th Infantry Division advanced only three miles in a little over two weeks at a cost of 6,000 casualties; the 1st Infantry Division took over 4,000 casualties for a four-mile advance elsewhere in the forest. Freezing, muddy conditions sent trench foot cases soaring even where German fire did not.

Why it matters

Hurtgen showed how completely terrain could cancel out the airpower and armor that had made the Allies dominant since Normandy. The battle bled several American divisions white just weeks before the Germans launched their own surprise offensive through the nearby Ardennes, the Battle of the Bulge, and some of the same exhausted units that had fought in the forest had to absorb that attack too.

How we know

Divisional casualty reports from the 1st, 4th, 9th, and 28th Infantry Divisions document the advance-per-casualty ratio that makes Hurtgen a byword for attritional fighting; the National Park Service's own historical designation cites the battle's length as the basis for calling it the Army's longest.
