The 'Maltese'Valentine [2]

The Matildas  on Malta were named Faulknor, Gallant, Greyhound and Griffin after the destroyers which escorted their convoy to Malta.

The tank detachment on Malta adopted a curious camouflage scheme dictated by local conditions. Much of the island being exposed and bare the most common feature was the stone walling that lined the roads and surrounded the fields, so the vehicles were painted to blend in with this. Other markings were entirely absent except for individual tank names which they seem to have retained from their previous service.

Mathilda 'Griffin'

Lorry-mounted 2-pdr anti-tank guns on a practice shoot in the Western Desert. 3 May 1942.The 2-pdr antitank gun equipped RA anti-tank regiments and later infantry battalions for much of the Desert War. The weapon was mounted on an ingenious three-legged carriage, giving it a low profile and which allowed the travelling wheels to be lifted clear of the ground so that the gun could easily traverse through 360 degrees. An armoured shield fined with an ammunition box protected its 5-man detachment and it weighed 1,760 lb. in action. Many were carried portee on the back of lorries during the Desert War. but when used this way often proved vulnerable to both small arms and shrapnel. Firing a solid AP round and with a penetration of '40mm at I,000m, the 2-pdr was highly effective against lightly armoured cars and tanks, but as the Desert War progressed it was quickly outclassed and could only engage with a hope of success from the flank at close range.
