Selby force at Sidi Barrani in December 1940

Brigadier Selby commanded a force for the attack on Sidi Barrani that was composed of three columns. He personally lead one column with the 3/Coldstream Guards, 6 field guns, three light tanks, and a machine gun company. The second column had a rifle company, a machine gun company and one field gun. They also had 8 dummy guns (I suppose to overawe the Italians). The third column had some infantry, artillery, and this time, 65 dummy tanks. I suppose the use of dummy equipment was to give the appearance of greater force, as they were opposed by large numbers of Italian troops. The whole purpose was to break the Italian morale. This is drawn from Gavin Long's To Benghazi.
