 The Italian artillery opened fire on the mosque and every operational tank the Babini Group had left, advanced towards the Pimple and the mosque.C Squadron, in its slower A9s (Cruiser Mk I) and A10s (Cruiser Mk II), arrived and the commander of F Battery, 4th RHA drove in a truck next to the tank of the 2nd RTR commander, directing the guns, which threw up clouds of dust, obscuring the movements of the tanks.The British tanks had the advantage of radio, unlike most of the Italian tanks, which had to move to an objective and then stop while the commanders dismounted to receive orders.
