Following the retreat of Allied forces from the mountain passes at
Olympus and
Servia,
British Commonwealth forces began to set up defensive positions at the coastal pass at
Thermopylae, famous for the
Battle of Thermopylae in 480 BC. The New Zealand Army's
2nd Infantry Division under Lieutenant-General
Bernard Freyberg was given the task of defending the pass, while elements of the Australian
6th Infantry Division, under Major General
Iven Mackay, defended the village of
Brallos. In the New Zealand sector, the
5th Brigade was deployed in the foothills along the coastal road south of
Lamia near the
Spercheios River, covering the bridges on the road to Larisa. The
4th Brigade was positioned on the right flank, where it had established coast-watching patrols. On 21 April, German air reconnaissance reported that the defense lines included only light field fortifications in the initial stage of construction, and that British troops were being evacuated from
Salamis Island. On the morning of 23 April,
ANZAC Corps was ordered to retreat. It was decided that Thermopylae and Brallos would nevertheless be held by a rearguard comprising two brigades. The New Zealand 6th Brigade, under Brigadier
Harold Barrowclough and the Australian 19th Brigade were to hold the passes as long as possible, allowing the other units to withdraw. Vasey said: "Here we bloody well are and here we bloody well stay." This was interpreted by Vasey's
brigade major, A. T. J. "Ding" Bell, as meaning that the brigade would "hold its present defensive positions come what may", until the withdrawal had been completed. ==Action==
