The Rats of Tobruk was the name given to the soldiers of the garrison who held the Libyan port of Tobruk against the Afrika Corps, during the Siege of Tobruk in World War II. The siege started on 10 April 1941 and was finally relieved at the end of November.
Between April and August 1941, around 14,000 Australian soldiers were besieged in Tobruk by a German–Italian army commanded by General Erwin Rommel. The garrison, commanded by Lieutenant General Leslie Morshead, consisted of the 9th Australian Division (20th, 24th, and 26th Brigades), the 18th Brigade of the 7th Australian Division, four regiments of British artillery, Polish Independent Carpathian Rifle Brigade, and 3rd Indian Motor Brigade.
In what proved to be a propaganda mis-step, Lord Haw-Haw derisively referred to the Garrison as "poor desert rats of Tobruk" during radio broadcasts. This was probably mostly due to two factors:
The Australians gave themselves the nickname 'the Rats of Tobruk' after Radio Berlin described the Australians as 'caught like rats in a trap'.
The old warships that helped the Rats of Tobruk with supplies and evacuation of the wounded were insulted by Radio Berlin, being called a 'pile of scrap iron'. The Australians therefore called them 'The Scrap Iron Flotilla'.
With typically Australian dry wit, Australians reclaimed the name as a badge of pride, even going so far as to strike their own unofficial medal bearing the likeness of a rat. The metal used to make the medals came from a German bomber that the Rats had shot down with captured German guns. Throughout the conflict, the Axis attackers had at least twice the manpower and had the advantage of strong air support, while the Tobruk garrison had little air support because of the remoteness from friendly air bases. This made the supply of the garrison, necessarily by sea, very difficult with ships having to arrive, unload and depart under the cover of darkness.
