During the Boer War, three Australian lieutenants are on trial for shooting Boer prisoners.

The trial does not progress as smoothly as expected by the General Staff, as the defence puts up a strong fight in the courtroom.

In 1879 South Africa, the administrators of the British Cape Colony have designs to eliminate the Zulus as a hindrance to their colonial economy. To that end, the British present King Cetshwayo with an impossible ultimatum to provoke a war they are sure they can win easily with their rifles and artillery against native spears. However, that war proves more difficult than the arrogant British commander, Lord Chelmsford, expects as his overburdened army fruitlessly searches for the elusive enemy. However, in the shadow of a hill called Isandlwana, the overconfident British army learns to its sorrow just how badly they have underestimated the tactical skill and might of the Zulu nation.

Mallory and Miller are back. It seems that there was traitor with them at Navarone, whom they thought was executed. But it seems that not only was he not executed, and he was not a traitor but a German spy. Intelligence believes he made it to Yugoslavia and is now with the Partisans. So, Mallory and Miller being the only ones who can positively identify him are sent along with a unit called Force 10, which is led by Colonel Barnsby, who objects to their presence. It seems that Force 10 has a mission of their own which Mallory and Miller know nothing about. When their plane is shot and most of the team is killed, they mistakenly believe that some of the locals they meet are Partisans but in reality are German Allies, so they are taken prisoner, and have to convince the German commander that they are not spies or else they will be killed.

In 1943, in the Russian front, the decorated leader Rolf Steiner is promoted to Sergeant after another successful mission.

When Colonel Brandt gives the order to leave the position in the front, Stransky does not retransmit the order to Steiner's squad...
