Operation Merkur (Mercury), the ‘Battle of Crete’.
German Plan of Attack and assault troops, deployed forces, intelligence, the fighting and losses on Crete.
The same time as on April 21, 1941, in Larissa the commander of the Greek forces, General Papagos, capitulated and the Balkans campaign so went almost to the end, a briefing took place at the advanced Führer Headquarter on the Semmering, which dealt with whether Crete should be conquered.
The aim of the meeting was to clarify the question for which target the paratroops should be used: Malta or Crete.
In the discussion, in which Jeschonnekk, Jodl and Keitel were present, was also Luftwaffe General Student involved. He pointed out that such a strong position as Crete should not be controlled by the enemy.
The coasts of Crete were controlled by the combative British Mediterranean fleet, including appropriate air protection. Thanks to its two airfields the British could control from the island – as unsinkable aircraft carrier – the entire eastern part of the Mediterranean and the Balkans.
In the hands of the Germans, however, they would definitively then rule over the Aegean Sea, because with it the British deployment in the eastern Mediterranean would be put to an end. Crete could also serve the Luftwaffe as a starting point for other operations.
For the final decision eventually Hitler was summoned and Student contributed to him that a conquest of the island is possible from the air. Then Hitler decided that the attack on Crete should be performed.
Student then worked out a detailed plan of attack, which was then approved on April 25 by Hitler’s ‘Directive No 28’ as ‘Operation Merkur’.
The command of the operation was given to General Löhr, the commander of Air Fleet 4, which ensure that all Air Force and Army units were under his control. These included primarily the VIII. Flieger Corps under the command of Air General von Richthofen, which was responsible for the air support of the operation, and the XI. Air Corps under General der Flieger Kurt Student, which would perform the actual airborne operation.
Since the beginning of 1941 the 7th Air Division under Lieutenant-General Süssmann and the 22nd (LL) Infantry Division (LL for ‘Luftlande’, means ‘air landing’) were parts of the XI. Air Corps. Since the latter was not available for the operation on Crete, in their place the 5th Mountain Division under Major General Ringel and parts of the 6th Mountain Division were given to General Student.
The leadership of the necessary air transport units was in the hands of Major General Conrad. The light transport ships for the provided sea transport were under Admiral Schuster. The date for the start of the operation, finally, 20th May was declared.
German Plan of Attack
Since not enough transport aircraft were available to all land forces at the same time, the plan was to take the four targets with a total of three groups in two waves.
The first wave was to land at 07.15 am in the section Maleme (West Group) and in section Chania (Group Center); the second wave was to Y-time plus 8 hours – i.e. at 15.15 hours – jump near Rethymno (Group Centre) and Heraklion (Group East). General Loehr was convinced that all the strategically important points could be taken in one day.
The command of the first wave of the West Group was given to General Meindl, commander of LL (air landing) Assault Regiment, a powerful special unit. Meindl paratroops were trained for such risky operations and experienced in the use of gliders.
The Group Centre was under the command of Major General Süssmann, while the Group East was commanded by Lieutenant General Ringel of the mountain troops.
Crucial to the success of the operation was the rapid seizure of airfields and the main cities of the island, so Maleme and Chania. The units in the East should take the cities Rethymno and Heraklion including their airfields – and all this in a single day. An ambitious, bold and risky plan.
The German assault troops
The troops employed for the parachute and airborne landings were under the command of General Command XI. Air Corps leaded by General Student, who was 51 years old at the beginning of the ‘Operation Merkur’. Kurt Arthur Benno Student had been a flying officer during World War One and was later adopted for the Reichswehr. Since the beginning of WW2 in Poland, but particularly on the Western Front, already several successful operations succeeded under his leadership.
For this new operation the entire 7th Air Division under the command of Major General Süssmann with 11,500 men, and the Airborne Assault Regiment Meindl which comprised about 3,500 men was under his command. This force war increased by army troops, which were composed mainly of mountain troops of the 5th Mountain Division and several battalions of the 6th Mountain Division.
The air transport for these troops, their weapons and equipment was the task of Major-General Conrad, who succeeded to deploy 533 transport aircraft Ju 52/3m and 70 gliders DFS 230.
General von Richthofen’s VIII Air Corps had the mission to protect the transport aircraft en route to and from Crete and to attack recognized enemy positions on the island. For this task 280 bombers, 220 fighters and heavy fighters, 150 dive bombers and 40 reconnaissance aircraft were available to him.
For the transfer of parts of the mountain troops, of supplies and heavy weapons to Crete by sea, two squadrons of motor sailer and two steamers squadrons were provided (the steamer squadrons were finally not placed), which should be formed by ‘Admiral Southeast’.

Thanks to their secret signals intelligence ‘Ultra’, the British were informed in detail about the German plans. A few hours before the airdrops, the British had already be aware of the precise strengths of the land, sea and air forces involved, the precise attack hours, the landing grounds and the battle tactics.
Already since May 17 ‘Creforce’ expected an invasion by 25,000-35,000 German troops who would be airlifted. Additionally, it was expected to 10,000 further men, which should land from seaside under the cover of Italian warships.
In contrast, the German side did not know much about their opponents, which is also reflected in the operational command of the XI Air Corps from May 12, while admitting that the situation in Crete is little understood.
Moreover, the enemy positions were not recognized, but only the well-designed dummy positions. Thus, the first airstrikes previous to the airdrops went naturally into the void.
The paratroopers were not only surprised by the strength of the British, Commonwealth and Greek troops on the island, but also of the hostility of parts of the population. Had the British not committed very strange tactical mistakes, then the Crete operation could easily end in the first few hours in a disaster for the Germans.
Battle of Crete
The attack began in the early morning of May 20, 1941. After heavy air raids the Assault Regiment General Meindis landed at Maleme in the area of 5th New Zealand Brigade; the rest came down along the road Alikianu-Chania, close to Galatas, to attack Chania.
The New Zealander at Maleme were unable to build a cohesive defensive position because of incessant air strikes and a lack of radio equipment. At night, the 22nd battalion was forced to abandon the airfield and return toward the 23rd battalion. By contrast, the Germans were stopped at Galatas, and also the paratroopers landed in Rethymno and Heraklion failed to capture these airfields.
The next morning, the Germans occupied the airfield of Maleme, without encountering direct resistance. The New Zealanders tried in vain to recapture the airfield and were thrown back towards Platanias. The two German battle groups now began to coordinate their operations and proceed to Chania.
In the second phase of the battle, the Allies tried to hold the bay of Suda while the Germans tried to further expand their positions. On May 25, Galatas fell, and on May 27, Freyberg had to recognize that the Allied positions were not to hold on. He retreated then to the south. Meanwhile, the Germans had taken Chania and Suda and urged, to relieve their troops in Rethymno and Heraklion.
From May 29 to 30, the Allies held in Sfakia a bridgehead to evacuate their troops; the crew of Rethymno but was forced to surrender. The following day, the last soldiers were evacuated, and the Germans entered Sfakia.
The Allies had been able to save 17,000 troops, their losses amounted to 17,800 men. The Germans lost about 7,000 dead, missing and wounded – nearly a third of their landing troops. They should never perform an airborne operation on this scale.
Losses on Crete
|Lost on sea||c.2,000||-||-|
The loss of the Greek army could not be found. It is estimated that a total of 5,000 soldiers were lost (killed, wounded, PoWs).
|Arm of Service||Killed||Wounded||Missed|
The loss of more than 3,000 paratroopers (by a total of 8,000 in action) marked a turning point in history and the use of German paratroops. And the Air Force lost during this operation more than 200 transport aircraft.
And although the conquest of the island was a great success, since Germany thus came into possession of a valuable strategic point in the Mediterranean, Hitler decided on 17 July 1941: ‘Crete has proved that the days of the paratroops are over. The parachute arm is just a pure surprise weapon. The surprise factor has now worn.’
And indeed, the German paratroops was henceforth rarely used for airborne operations.
For the British Empire, the loss of Crete presented not only a military defeat, but it was a real humiliation: The British Expeditionary Force, with more than 40,000 troops, which were expecting the Germans in well-built and camouflaged positions deployed over the entire northern part of the island and which were supported by a powerful naval force, and even in spite of their considerable numerical superiority and exact knowledge of the enemy’s plans, had not been able to defend the island successfully.
But this, the British paid a high price: Nearly 4,000 dead, three times as many prisoners.
Given the losses of the Royal Navy in particular: sunken were three cruisers, seven severely damaged, eight destroyers sunk and nine damaged. Additional, an aircraft carrier and two battleships out of action.
