The British armoured forces on Crete consisted of 'C' Squadron, 3rd (King's Own) Hussars with 16 Vickers MK. VI and B Squadron, 7 Royal Tank Regiment, with Matilda IIs. The Matildas were split up into three pairs deployed at various points, with a final three at another, for a total of 9 vehicles. 3rd Hussars only had 13 light tanks operational and these were divided into one group of six and another of seven (in troops of three tanks iirc).
No Cruiser tanks were on Crete and likewise no Matildas were sent to Greece.
