VI light tanks. Benghazi was the port closest to the frontline. However, Axis bombing had rendered it unusable for landing supplies. The 2nd Armoured Division therefore had to rely on overland routes from Tobruk, which was about away via the coastal road, or via desert tracks. A lack of transport meant the British Army created a series of static stockpiles to supply their forward area. This made it impossible to supply a garrison west of El Agheila, which was the most favourable defensive position. It also restricted the mobility of the 2nd Armoured Division, which could not move beyond the range of their supply dumps. The terrain between El Agheila and Benghazi was optimal for armoured warfare, and no easily defensible infantry position existed. Lieutenant-General Philip Neame, GOC Cyrenaica Command, believed his position was untenable without a fully equipped armoured division supported by two complete infantry divisions and adequate air support. The only other major formation available to Neame was the 9th Australian Division. It was under-equipped, under-trained, and lacked direct communication with the 2nd Armoured Division. One of the 9th Australian Division's brigades remained at Tobruk. The other two were positioned north of Benghazi to hold the high ground of the Jebel Akhdar. The 3rd Armoured Brigade was based southeast of Mersa Brega, where the 2nd Support Group was located. Neame was ordered to give ground if attacked, as the conservation of his force was important. The 2nd Armoured Division had the conflicting objectives of avoiding tank losses while having to be ready to operate offensively against the flanks of any attacking Axis armoured force. Neame also predicted that once operations got underway, the 2nd Armoured Division's tank numbers would rapidly dwindle due to breakdowns. Axis offensive March After the destruction of the 10th Army, Italy dispatched reinforcements to its frontline. This included four infantry divisions, the 102 Motorised Division "Trento" and the 132nd Armoured Division "Ariete". Germany supplemented this effort with the two-division strong ( Erwin Rommel). At the end of March, the German 5th Light Division (147 tanks) and the "Ariete" Division (46 M13/40s) were on the border of Cyrenaica. The British underestimated the size of the Axis effort, believing that only four divisions would be available to them until the end of May, of which only two could be used in offensive operations due to supply constraints. Royal Air Force (RAF) aerial reconnaissance observed Axis troop
