The cost to Germany was so great that Hitler decided that there would not be another major airborne operation. Can’t find the source but Hitler said to Student later something to the effect that there would be no more large scale airborne operations, I think partly because they required surprise and surprise was lacking in such an operation.
Conversely, the Allies saw Crete as a demonstration of the potential of airborne operations and, not having suffered the losses of the Germans from such an operation except as defeated defenders, were highly impressed and pressed on to launch even bigger airborne operations later in the war.
The success of (some of) the Alllied airborne operations was attributable to proper preparation (the 6 P’s - Proper Preparation Prevents Piss Poor Performance) which was lacking Crete.
IV. Casualties and Losses
The figures for German casualties suffered in the Crete operations remain a matter of conjecture. Whereas German after action reports give total losses varying between 3,986 and 6,453 men, Winston S. Churchill states that more than 4,000 graves have been counted in the area of Maleme and Suda Bay and another thousand at Retimo and Heraklion.* In Churchill’s opinion the Germans must have suffered well over 15,000 casualties in killed and wounded. Part of the difference may be explained by the fact that the British estimated the number of men drowned in the sinking of the first convoy at 2,500 men. Actually, only two battalions had been embarked on vessels in that convoy and the air-sea rescue squadron apparently rescued most of the shipwrecked. In a recent study on German losses in Crete,

British military historians seem inclined to accept the highest German figures as correct.*
Some 350 German planes, more than half of them troop carriers, were lost or damaged.
The British were able to evacuate 14,800 out of a garrison of 27,500 men. Left behind were also the 14,000 Greek troops, either dead or captured. The Royal Navy suffered nearly 2,000 casualties and crippling losses which resulted in its withdrawal from the Aegean.
Chapter 22: Lessons
In view of the particular circumstances that surrounded the German seizure of Crete, its success should not be taken as proof for the contention that the airborne invasion of an island is the ideal solution in any similar situation. Comparisons with other theaters of war, for instance the British Isles, are misleading. The invasion of Crete was in a category by itself, but a number of lessons with general validity for similar operations can be learned from the German experience. In general, the success of an airborne operation against an island will depend on the following factors:
a. Control of the air above the island is essential for the successful execution of airborne landings. During the Crete operation the British had practically no aircraft based on the island and were unable to improvise effective air cover from North Africa because of the long distance between the air bases in Egypt and the fields on Crete.
b. Control of the sea around an island is next in importance. The invader’s navy must be able to provide full protection for the convoys that have to bring up tanks, heavy weapons, and supplies of all types. During the attack on Crete, British naval units cut off German seaborne transportation and thereby delayed the progress of the ground offensive, which in turn enabled the British to evacuate considerable forces to Egypt. German reinforcements, supplies, and-above all–tanks, artillery, and antitank guns could not be brought to the island by sea when they were most needed. The warning given by the German Navy before the start of Operation MERKUR-not to send naval convoys to Crete before the waters around the island had been cleared of the enemy–had been justified.

c. The command channels regulating interservice cooperation must be clearly defined and unity of command over both airborne and seaborne forces must be firmly established. During the invasion of Crete, the German command organization was unified, and for the first time an air force general was in overall command of air, ground, and naval forces. General Loehr, the commander of Fourth Air Force, set up his headquarters at Athens in close proximity to Twelfth Army and Navy Group South headquarters, which were instructed to give him all the support he needed. The command structure for Operation MERKUR was as follows: (chart)
In contrast to the simplicity of this command organization, the British ground and air force units were under independent local commanders who in turn were subordinate to the respective service commanders, Middle East, stationed in Egypt. The naval commander sailed with the fleet. All three service commanders, Middle East, reported through their ministries to the War Cabinet in London and received their orders from that source. To add to the confusion, General Freyberg, the New Zealand commander of the ground forces, also reported to his govern-
Page 143
ment half way around the world whenever he felt that this was necessary or in the interest of his country.*
Prime Minister Churchill sent messages directly to General Freyberg and intervened when he believed that his influence and encouragement would be of benefit. Thus, on 27 May, at a time when the fate of Crete was no longer in doubt and the local commander was preparing orders for withdrawal, Churchill telegraphed to the commanders-in-chief, Middle East: “Victory in Crete essential at this turning-point in the war. Keep hurling in all you can.”**
d. The element of surprise is essential to the success of an airborne operation which involves great risks under any circumstances. To achieve surprise, it is particularly important to maintain the secrecy of the offensive plans until the last minute. This will never be fully accomplished but several measures may be taken to deceive the enemy at least with regard to the exact time for the start of the attack. For example, whereas the logistical preparations at the jumpoff airfields for troop carriers and gliders may be accomplished well ahead of time, the airborne formations proper should be moved in as late as possible. The presence of parachute troops should be kept secret by restricting movements to and from the airfields of departure. Also, the enemy must be prevented from flying reconnaissance missions over the staging areas.
e. Other important factors are the intensive collection of intelligence and proper dissemination of information obtained. The terrain of the potential landing areas must be thoroughly reconnoitered by low-flying planes, aerial photography, and agents. By the time the parachute troops descend, the main enemy nests of resistance and defensive weapons must have been neutralized or the rate of jump casualties will be abnormally high.
German air reconnaissance during the period preceding the invasion was inadequate and the intelligence picture presented by the Luftwaffe did not correspond to the actual situation on the island. The British had succeeded in concealing fortifications and camouflaging their gun positions. Dummy flak positions were extensively bombed, while the real ones were not discovered. Some British positions were erroneously marked as artesian wells and the prison on the road to Canea was thought to be a British ration dump. Apparently, Twelfth Army had

more accurate information local agents. But, in the firm belief that the British intended to evacuate the island immediately after the first airborne landings and that the garrisons consisted of only 5,000 combat troops, the Luftwaffe refused to consider mole realistic estimates of the enemy preparations.
