Combeforce
Combeforce or Combe Force was an ad hoc flying column of the British Army during the Second World War, commanded by Lieutenant-Colonel John Combe. It comprised parts of the 7th Armoured Division of the Western Desert Force. The rapid British advance during Operation Compass forced the Italian 10th Army to evacuate Cyrenaica, the eastern province of Libya. In late January, the British learned that the Italians were retreating along the Litoranea Balbo from Benghazi. The 7th Armoured Division was dispatched to intercept the remnants of the 10th Army by moving through the desert, south of the Jebel Akhdar, Libya via Msus and Antelat, as the 6th Australian Division pursued the Italians along the coast road, north of the jebel.
The terrain was hard going for the British tanks and Combeforce, with the wheeled vehicles of the 7th Armoured Division, was sent ahead across the chord of the jebel. Late on 5 February, Combeforce arrived at the Via Balbia south of Benghazi and set up roadblocks near Sidi Saleh, about south-west of Antelat and north of Agedabia. The leading elements of the 10th Army arrived thirty minutes later and ran into the British ambush. Next day the Italians attacked to break through the roadblock and continued to attack into 7 February. With British reinforcements arriving and the Australians pressing down the road from Benghazi, the 10th Army surrendered later that day. From Benghazi to Agedabia, the British took captured and Having succeeded in its objectives, Combeforce was disbanded.
Background
Operation Compass
In early December 1940, the British Western Desert Force began Operation Compass, a raid against the Italian 10th Army, which had conducted the Italian invasion of Egypt in September 1940. The Italians had advanced to Sidi Barrani and established defensive positions in a line of fortified camps, which were overrun during the raid. Sidi Barrani was captured and the scope of Compass was extended to exploit the victory and the Italian garrisons in Bardia and then Tobruk were isolated and captured. The 10th Army attempted to establish a defensive line at Derna east of the Jebel Akhdar mountains, with XX Corps , comprising the 60th Infantry Division "Sabratha" and the Babini Group, an improvised armoured brigade, which had lost some of its tanks in Tobruk. The Babini Group, had all of the Fiat M13/40 medium tanks in Libya and held the south-west end of the defensive front near Mechili, the junction of several caravan routes, to block another British outflanking move.Derna–Mechili
On 22 January, the British advanced towards Derna, with the 19th Australian Brigade of the 6th Australian Division and sent another Australian brigade to reinforce the 4th Armoured Brigade of the 7th Armoured Division south of the Jebel Akhdar, for an advance on Mechili. On 23 January, Tellera ordered a counter-attack against the British as they approached Mechili, to avoid an envelopment of XX Corpo D'Armata di Manovra from the south. Communication within the Babini Group was slow because only the tanks of senior commanders had wireless; the other crews were reliant on flag signals limited to halt, forward, backwards, right, left, slow down and speed up. Next day, the Babini Group with 10 to 15 M13/40s attacked the 7th Hussars of the 4th Armoured Brigade which was heading west to cut the Derna–Mechili track north of Mechili. The Italians lost seven M13s by for the loss of one cruiser and six light tanks.The 4th Armoured Brigade was ordered to encircle Mechili and cut the western and north-western exits, while the 7th Armoured Brigade cut the road from Mechili to Slonta but the Babini Group had already retired into the hills. On 26 January, Graziani ordered Tellera to continue the defence of Derna and to use the Babini Group to stop an advance west from Mechili–Derna. During 27 January, a column of Bren Gun Carriers of the 6th Australian Cavalry Regiment was sent south from the Derna area to reconnoitre the area where the Italian tanks had been reported and was ambushed by part of the Babini Group with concealed anti-tank guns and machine guns; four Australians were killed and three taken prisoner. The 11th Hussars found a gap at Chaulan south of Wadi Derna, the Italians disengaged on the night of 28/29 January. Rearguards of the Babini Group cratered roads, planted mines and booby-traps and managed to conduct several skilful ambushes, which slowed the British pursuit.
Prelude
Pursuit from Mechili
At dawn on 4 February, the 11th Hussars left Mechili, along a route towards Beda Fomm, which had not been reconnoitred by ground forces to avoid alerting the Italians. The vehicles were loaded to capacity with supplies fuel and ammunition, the ration of drinking water cut to about a glass a day and halts for food and rest were cut by half. Low-flying air reconnaissance had reported that the going was difficult and for the first the route was the worst yet encountered. The journey began in high winds and bitter cold and by the time the tail end moved off the winds had risen to gale force. The head of the column drove into windblown sand which cut visibility to nil, while at the tail, drivers and vehicle commanders standing up reading compasses, were hit by frozen rain. By armoured cars had reached Msus, away, where the garrison left hurriedly and some cars followed up another to Antelat.Combeforce
By dawn on 5 February, the tracked vehicles and the rest of the 7th Armoured Division had reached Msus. Creagh had been informed by air reconnaissance that the 10th Army was retreating and Richard O'Connor ordered that the advance be pressed to cut off the Italian retreat. Creagh decided to send the wheeled vehicles on ahead, to block the Via Balbia between Benghazi and Agedabia as quickly as possible and to follow on to the south-west with the tracked vehicles, rather than westwards to Soluch. Combeforce consisted of an armoured car squadron from each of the 11th Hussars and King's Dragoon Guards, the 2nd Battalion The Rifle Brigade, an RAF armoured car squadron, six 25-pounder field guns of C Battery 4th Royal Horse Artillery and the 106th Battery RHA, with nine Bofors 37 mm anti-tank guns portee, a total of aboutDrive for Beda Fomm
Combeforce reached Antelat during the morning and by had observers overlooking the Via Balbia west of Beda Fomm and Sidi Saleh, about south-west of Antelat and north of Ajedabia, with the rest of Combeforce following on. An Italian convoy drove up about thirty minutes later and ran onto mines; the column was engaged by the British artillery, anti-tank guns and armoured cars, which threw the convoy into confusion. Some members of the 10th Bersaglieri tried to advance down the road and others looked for gaps in the ambush on either side of the road.Battle
The Bersaglieri had little effect, being unsupported by artillery, most of which was with the rearguard to the north. The attempts by the Italians to break through became stronger and in the afternoon, the 2nd Rifle Brigade crossed the Via Balbia into the dunes, to block the route south between the road and the sea. Combe also brought up a company behind the roadblock, placed some 25-pounders behind the infantry and kept some armoured cars manoeuvring in the desert to the east, to deter an Italian outflanking move. Several hundred prisoners were taken but only a platoon of infantry could be spared to guard them. The vanguard of the Italian retreat had no tanks, contained few front-line infantry and had been trapped by the ambush which forced them to fight where they stood.While waiting for the 4th Armoured Brigade, Combe reconnoitred to the north and near a small white mosque found several long, low, north-south ridges with folds between, in which tanks could hide from the road as they moved back and forth to fire at close range. The brigade set off from Msus at but the journey was delayed by moving in single-file through a field of Thermos bombs. The brigade took until to cover the to Antelat, where they came into the range of Combeforce wireless transmissions. Combe briefed Caunter to head for the mosque north of the roadblock and then attack all along the Italian column, to reduce the pressure on Combeforce. Caunter ordered the 7th Hussars and the artillery at full speed to the Via Balbia followed by the 2nd RTR in their slower tanks; the 3rd Hussars were sent north-east to cut the routes from Soluch and Sceleidima. The brigade moved westwards on hard, flat sand, raising clouds of dust and soon reached the Via Balbia.
On 6 February, Combeforce had faced some well-organised attacks with artillery and tank support, which had been repulsed by C Battery RHA and nine Bofors anti-tank guns of the 106th RHA. Italian infantry had used wrecked tanks as cover for their advance, while many more lost hope and surrendered. During the night, some tanks from the Pimple arrived and four were knocked out by mines and gunfire, four got through with some lorries and the rest gave up. The Italians had only about thirty tanks left and planned to force their way through Combeforce at dawn, before the British could attack the flanks and rear of the column.
The attack had artillery support, as soon as it was light enough to see movement by the anti-tank guns portée of the 106th RHA. The infantry of the 2nd Rifle Brigade stayed under cover as they were overrun by the Italian tanks, which concentrated on the RHA anti-tank guns. C Battery 4th RHA fired on the Rifle Brigade positions as the tanks passed and the Rifle Brigade resumed fire on Italian infantry following the tanks, to pin them down. The M13s knocked out all but one anti-tank gun and kept going into the reserve company area but the last gun was driven to a flank by the battery commander, his batman and the cook. The improvised crew commenced firing as the last M13s drove towards the Officers' mess tent put up the day before and knocked out the last tank from the tent. On the road, the Italians could hear British tank engines on the flanks and from the rear and further north, the 4th Armoured Brigade surrounded another group, at which point the Italians surrendered.
