The Germans in the Prison Valley stayed in position for all of 21 May. They had expected a British counter attack, but there was not one. The paratroops who jumped into the area near Platanias, they took heavy losses. 80 men, though, took a farm that was near the beach. This was near Pirgos.
The group of small ships was transporting a mountain battalion, an antiaircraft regiment, and groups with heavy weapons. They turned back because of the British warships. They made another attempt at midday. They encountered British warships again, and scattered with heavy losses. A relatively small number of ships were lost. Italian motor boatsand destroyers were able to rescue many men.
On 22 May the Germans in the assault regiment were to hold their ground. The mountain troops would assist in holding the air field. The Germans planned to bring in more mountain troops during the day. They were to make an attack "through the hills". The general commanding the mountain troops was put in command of all German troops on Crete. He was to "clear the island from west to east".
