under the command of her father, Major Petrovich. Mallory and Barnsby escape and meet a patrol of real Yugoslav partisans led by Lescovar, who has gained Petrovich's trust. Mallory and Barnsby are taken to the camp, which lies near a hydroelectric dam. An arch bridge spanning the river ravine is set to be used by a German force for an impending assault on the partisans, who have been unable to destroy the bridge. Barnsby reveals that the bridge is Force 10's target. Mallory convinces Petrovich to mount a rescue mission of demolitions expert Miller, using Lescovar and Marko, a loyal partisan. The four re-enter the camp at night, with Mallory and Barnsby posing as captives, and Lescovar and Marko disguised as Chetniks. Drazak discovers that Maritza must have helped Miller and Mallory escape, and begins beating her viciously. Schroeder and Reynolds are killed in a gun battle, but the others escape with a badly beaten Maritza and the recovered explosives. Miller reveals that the bridge is impregnable, which Barnsby refuses to accept. Mallory hits upon the idea of destroying the upstream dam, to use the sudden onrush of millions of gallons of water to destroy the bridge. A night-time air drop is arranged to replace Force 10's lost supplies, but Lescovar, revealed to be the saboteur, calls in German planes to stop the drop. Maritza catches Lescovar in the act, but he kills her before she can warn the others, and German planes bomb the illuminated drop zone, killing numerous partisans. Petrovich, angered by the botched air drop, orders the men to be sent to Marshal Tito's headquarters for transport back to Italy. Accompanied by Lescovar and Marko, the team instead infiltrates the German marshaling yards at Mostar to steal explosives. Lescovar again betrays them, alerting a German sergeant to their presence. Marko sacrifices himself to save the others, who escape with Lescovar aboard a train leaving for Sarajevo. Lescovar is questioned by the others, who have grown suspicious of him. Lescovar initially denies the accusations, but gives himself away and is shot dead by Barnsby, who then asks Mallory to return the favour by helping him accomplish Force 10's mission. Jumping the train near the dam, the team splits up: Miller and Weaver run a diversion, while Mallory and Barnsby sneak into the dam. Weaver runs into Captain Drazak and kills him in a knife fight.
