What is the last name of the person who crashes an aircraft into a bridge's foundation?
The US Army is conducting a fighting retreat. A high bridge spans a ravine on the Bataan Peninsula. After the army and some civilians cross, a 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, setting up heavy machine guns in sandbag fortifications. They succeed in blowing up the bridge, but their commander, Captain Henry Lassiter, is killed by a sniper, leaving Sergeant Dane in charge.
One by one, the defenders are killed, while Ramirez succumbs to malaria. Despite this, the outnumbered soldiers doggedly hold their position. Malloy shoots down a Japanese aircraft with his Tommy gun before being killed. Dane and Todd creep up, undetected, on the partially rebuilt bridge and throw Mk 2 hand grenades, blowing it up. 
There is also tension between Dane and Todd. 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 Steve Bentley and his Filipino mechanic, Corporal Juan Katigbak, work frantically to repair a Beechcraft C-43 Traveler aircraft. They succeed, but Katigbak is killed and Bentley is mortally wounded. Dying, he has explosives loaded aboard and crashes the C-43 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 with bayonets fixed on their M1903 Springfield rifles. Epps and Feingold are killed, leaving only Dane, Todd, and a wounded Purckett alive. Purckett is shot, while Todd stabbed through the back by a Japanese soldier who had only feigned being dead. Before he dies, Todd admits to Dane he is Burns.
