The forces in Tobruk

In early to mid-April 1941, the forces in and around Tobruk included the 24th Australian Infantry Brigade (two battalions), the 18th Australian Infantry Brigade, the 20th and 26th Australian Brigades, initially outside the perimeter. They entered "on the night of 9th April". As we noted, there was the remains of the 3rd Armoured Brigade. There was no medium artillery. There was only three 25pdr regiments, two anti-tank regiments (each one less a battery), and 16 heavy AA guns and 59 light AA guns. Most were used to defend the harbour. This is based on the account in Vol.II of the Official History.
