The entire assault on Crete was code named "Operation Mercury" () and was controlled by the 12th Army commanded by Field Marshal Wilhelm List. The German 8th Air Corps () provided close air support; it was equipped with 570 combat aircraft. The infantry available for the assault were the German 7th Air Division, with the Air-landing Assault Regiment (Luftlande-Sturm-Regiment) attached, and the 5th Mountain Division. They totalled 22,000 men grouped under the 11th Air Corps () which was commanded by Lieutenant General Kurt Student who was in operational control of the operation. Over 500 Ju 52s were assembled to transport them. Student planned a series of four parachute assaults against Allied facilities on the north coast of Crete by the 7th Air Division, which would then be reinforced by the 5th Mountain Division, part transported by air, and part by sea; the latter would also ferry much of the heavy equipment.
