Another one for the Peanut Gallery - in addition to the (mis?)-use of unopposed armor at Gallabat, there's also the battle at El Uach/El Wak (Somalia) - where the South African 1st Light Tank Company was able to stampede the defenders and give the Commonwealth a victory during a very dark time.

Towards Dave's interest in the Italian deserters,
'This is Colonel Orde Wingate of the British Army and I want to see your commanding officer immediately' he said. 'Wait here, Sir' the writer told him and found his commanding officer, Major 'Plumber' Clark asleep in his tent. 'Oh' he said, 'He must be the chap trying to organise the Abyssinian irregulars into a regular unit to help us round up the thousands of Italian deserters in the bush - bring him in.'
It was many years later that the writer read the story of Colonel Wingate. He had previously been in Palestine, organising Arab irregulars, then he escorted Emperor Haile Selassi back to Addis Ababa. He became famous in Burma with the 'Chindits' and is remembered as 'General Lord Wingate of Burma'.
