The command situation in Greece in April 1941

 The British command organization in Greece had become rather problematic. The Australian general Blamey was now a corps commander with his headquarters at Gerania. He commanded the New Zealand Division, the Australian division, and the 12th Greek Division. The Central Macedonian Army had a Greek commander. General Mackay now reported directly to General Wilson. Wilson had an advanced headquarters near  Blamey's. Wilson also had a rear headquarters in Athens. The independent British air commander had a headquarters in Athens, as well. Athens also had a British independent naval staff. For some reason, there was also a British Military Mission in Athens. 

Your ordinary British army officer generally thought that Wilson should have been "supreme commander of British forces in Greece". Apparently, they thought that the air officer should have been Wilson's deputy. They also thought that Wilson should have stayed in Athens for easy communication with the British ambassador and the commanders of the various organizations. There should not have been any British Military Mission and "the Military Attache should have been part of Wilson's staff". You would then have Blamey's corps headquarters command "all British and Greek troops in the Aliakmon position". The British had "public school knowledge of French". That and an interpreter should have been adequate for communications with the Greeks. The Australian General Mackay arrived at Sotir, at Lee's headquarters, shortly before midnight on 8 April. He was to command the Vevi Gap position, which conveniently enough had no infantry in place. The Australian brigadier Vasey, who commanded the 19th Brigade, but his battalions were absent. One was moving forward still, and another was near Veria. The third had not arrived in Greece, yet. All that Lee had under his "command were the 64th Medium Regiment, the 2/1st Australian Anti-Tank Regiment", and "the New Zealand Machine Gun Battalion". It seemed possible that Lee might add the 1st Armoured Brigade to his group of units. This is based on the account in "Greece Crete and Syria" by Gavin Long.
