In 1942 he was seconded to the 8th Battalion, the Durham Light Infantry. By March 1943 Rommel was trapped in Tunisia between the 8th Army in the east and the 1st Army in the west. After routing the Americans at the Kasserine Pass he dug his army in at the old French frontier position at Mareth and, a sick man, departed for Europe, leaving Von Arnim in charge. Montgomery began his attack through its northern end, via the formidable Wadi Zigzaou. Lucas was serving in D Company, 8th Battalion, Durham Light Infantry, part of 151 Brigade, which established a bridgehead on the far side of the Wadi. In order to widen the bridgehead the Royal Engineers had built a causeway across the Wadi under intense fire, only to see it wrecked by a cloudburst. Meanwhile 75 German tanks, infantry of 15 Panzer Division, a regiment from 90th Light Division and Ramcke parachutists were forming up at Zarat, to attack the brigade. The 8th DLI confronted the German assault with no supporting weapons – the few Valentine tanks and anti-tank guns were unable to cross the wadi - and no air support, since the aircraft had been grounded by torrential rain. The German attack began with accurate shelling of the Durhams' position, which caused many casualties. When the gunfire was at its heaviest Lucas, commanding the Bren Gun Carrier Platoon, answered an urgent call from A and B Companies for wireless sets and batteries. Undeterred by the murderous defensive fire sweeping the wadi Lucas went forward in his carrier through a gap in the minefield. He safely crossed the wadi and anti-tank ditch, all the time under heavy fire, and finally reached the forward companies with his valuable cargo. He then returned to Battalion H.Q. the way he had come. Later, under equally difficult conditions, he again undertook the hazardous journey this time with rations and ammunition. There is no doubt that his actions enabled the forward troops to hold onto their positions and Captain Lucas was awarded the Military Cross. Lucas remained with the 8th DLI during the rest of the North African Campaign. In July 1943 the 8th DLI was part of the invasion force for Operation Husky, the allied campaign to capture Sicily from the Italian and German armies. Alerted to the invasion, the Germans airlifted paratroopers to Catania, north of the 8th Army's landing sites around Syracuse. One of the major links into mainland Sicily was the Primosole Bridge over the River Simeto between Syracuse and Catania. British Paratroopers were sent to capture the bridge, but, although the British 1st Parachute Brigade managed to take the bridge, they were forced to retreat due to an overwhelming enemy presence. The Durham Light Infantry and the 44th Royal Tank Regiment raced north to reinforce the paratroops. After wading the Simeto north of the bridge two companies of the 8th DLI succeeded in establishing a bridgehead on the opposite bank, taking the Primosole Bridge over which the remaining two companies of the Battalion were able to pass to reinforce the leading companies. Despite heavy casualties in hand to hand fighting the 8th DLI held the bridgehead until they were reinforced during the night by the 9th and 6th DLI. In the course of the battle Lucas' position in the east of the bridgehead was struck by a German shell; he was seriously wounded in the back and hand and evacuated to Malta. Lucas fought to regain his fitness and rejoined the Royal Warwickshire Regiment after the war. In 1947/48 he served in Palestine in anti-terrorist operations and was mentioned in despatches for gallant and distinguished services during the period 27 September 1947 – 26 March 1948. Afterwards he was seconded to the King's African Rifles and fought against the Mau-Mau in Kenya and against communist terrorists in Malaya. His final appointments were as commandant of the Army School of Physical Training at Aldershot and then as administrative commandant of the Defence NBC School at Winterbourne Gunner, Wiltshire.
