Planning in relation to Greece in 1940-1941

In Germany, Hitler ordered planning to "occupy Northern Greece" as early as 12 November 1940. He would use ten German divisions for the operation. By late November, Hitler decided to occupy all of Greece. He would conduct the operation in March, he decided in December. After seeing the British successes in Cyrenaica and the Greek successes in Albania, he decided that the invasion army needed to be larger. He was thinking about the invasion of Russia when he planned the Greek invasion. One thing he wanted was to protect Rumanian oil fields from British bombers in Greece.
You saw the British fighting in east Africa against the Italians. The British advance to Tripoli would be stopped, so free up resources for Greece. The New Zealand Division was planned to be part of the Greek operation. The latest thinking was to send the British 6th Division to Greece and replace it in North Africa with the 9th Australian Division, which was untrained and new. He hoped to also send the Polish Carpathian Brigade to Greece. The Australian General Blamey insisted on sending the 6th Australian Division to Greece and keeping the raw 7th Australian Division in Cyrenaica. They would reorganize the Australian divisions and change which brigades were assigned to each division. The prestige of General Freyberg meant that the New Zealand division was treated as being one of the best divisions. The New Zealand Division arrived in Greece on 7 March when they were treated to cheering from the Greek people. The Greek leader assured the British that whatever happened, the Greek army would fight the expected German invasion. This is based on the account in "Greece Crete and Syria" by Gavin Long.
