Bataan

The United States Army is conducting a fighting retreat. A high bridge—a wooden trestle on massive stone pillars—spans a ravine on the Bataan Peninsula. After the Army and some civilians cross, an ad hoc group of thirteen hastily assembled soldiers from different units is assigned to blow it up and delay Japanese rebuilding efforts as long as possible. They dig in on a hillside. They succeed in blowing up the bridge, but their commander, Captain Lassiter, is killed by a sniper, leaving Sergeant Dane in charge.
One by one, the defenders are killed, except Ramirez, who succumbs to malaria. Despite this, the outnumbered soldiers doggedly hold their position. Dane and Todd creep up, undetected, on the bridge the Japanese have partially rebuilt and throw hand grenades, blowing it up. Malloy shoots down an enemy aircraft with his Tommy gun before being killed.
Dane suspects that Todd is a soldier from his past named Danny Burns who was arrested for killing a man in a dispute, but escaped while Dane was guarding him.
Army Air Corps pilot Lieutenant Bentley and his Filipino mechanic, Corporal Katigbak, work frantically to repair a Beechcraft C-43 Traveler aircraft. They succeed, but Katigbak is killed and Bentley is mortally wounded. Bentley has explosives loaded aboard and flies into the bridge's foundation, destroying it for a third time.
The remaining soldiers repel a massive frontal assault, inflicting heavy losses and ultimately fighting hand-to-hand. Epps and Feingold are killed, leaving only Dane, Todd, and a wounded Purckett alive. Purckett is shot, while Todd is stabbed through the back by a Japanese soldier who had only feigned being dead. Before he dies, Todd admits to Dane he is Burns.
Now alone, Dane stoically digs his own marked grave beside those of his fallen comrades. The Japanese crawl through the ground fog near his position before opening fire and charging. Dane fires back; when his Tommy gun runs out of ammo, he switches to an M1917 Browning machine gun. He continually fires it directly into the camera lens as the end card reads: "So fought the heroes of Bataan, Their sacrifice made possible our victories in the Coral and Bismarck Seas, at Midway, on New Guinea and Guadalcanal. Their spirit will lead us back to Bataan!"
