During 14 April 1941, you had the 5th New Zealand Brigade sitting in the Olympus Pass. The Katerini-Elasson road ran through the Olympus Pass. The brigade was deployed with the 23rd Battalion to the right of the brigade. The 22nd Brigade was sitting in the center of the front. The Maori's of the 28th Battalion were on the left. The 28th Battalion was located at Skoteina. The brigade had some artillery in support. They had the 5th Field Regiment and an anti-tank battery.
There was a plan to move the 6th Brigade into a spot on the left of where the 5th Brigade was located. They saw some German vehicles "at 5pm on 14 April. By the time the artillery was given permission to fire on the vehicles, they had moved out of sight."
During the night ofo 14 to 15 April, the New Zealand troops could see German vehicles bringing troops forward. Sometime around 11pm, German motorcycles drove up the pass. They drew machine gun fire, and the next morning they found five motorcycles lying next to the road.
During 15 April, there was more German vehicle traffic. They drew artillery fire, but were not fired upon by British artillery. It was only by 4:30pm that the Germans started to return artillery fire. The Germans did not make any attempt to attack on 1`5 April. This is based on the account in "Greece, Crete, and Syria" by Gavin Long.
