The advance on February 4th, 1941

Brigadier Savige's brigade had no move forward in a piece-meal fashion. The 2/5th Battalion was reduced to marching. The 2/6th and 2/7th had borrowed trucks. General Mackay had already decided to push Robertson's 19th Brigade through the 17th, with all battalions on borrowed trucks. Three of 11th Hussars armoured cars lead the advancing 19th Brigade, along with a troop of 6th Australian Division Cavalry. At one point, they surprised Italians laying mines. As they disembarked to remove the mines, they were his by machine gun fire that disabled or destroyed all three armoured cars. This ambush took place near dusk on February 4th. This is based on the account in To Benghazi.
