Italian capture of Kassala

Amedeo, Duke of Aosta the Viceroy and Governor-General of Italian East Africa (Africa Orientale Italiana [AOI], commander in chief of Comando Forze Armate dell'Africa Orientale Italiana (Italian East African Armed Forces Command) and Generale d'Armata Aerea (General of the Air Force) ordered an Italian attack on Kassala, Anglo-Egyptian Sudan to begin on 4 July 1940 after Italy had declared war on Britain and France on 10 June. Three columns of Italian and colonial forces comprising about 6,500 men launched the assault, supported by the Regia Aeronautica and some cavalry squadrons acting as vanguards.^[1]

Kassala was defended by fewer than 500 men of the Sudan Defence Force (SDF, Major-General William Platt the al-qa'id al-'amm [Leader of the Army], known as the Kaid) and local police, who remained under cover during a twelve-hour bombardment by the Regia Aeronautica, then knocked out six Italian tanks and inflicted considerable casualties on the attackers. At 1:00 p.m., Italian cavalry entered Kassala and the defenders withdrew to Butana Bridge, having lost one man killed, three wounded and 26 missing, some of whom rejoined their units.^[2][3] Italian casualties were 43 men killed and 114 wounded.^[1] At Kassala, the 12th Colonial Brigade built anti-tank defences, machine-gun posts and strongpoints.^{[4][lower-alpha 1]}

During the Italian attack at Kassala, General Pietro Gazzera, the Governor of Galla-Sidamo captured the Sudan fort of Gallabat with a battalion of Italian colonial troops and banda (irregulars with Italian officers). Gallabat was placed under the command of Colonel Castagnola and fortified. Karora was occupied unopposed and on 7 July, another colonial battalion and banda supported by artillery and aircraft, attacked Kurmuk and overcame sixty Sudanese police after a short engagement.^[4]

The Italian attacks had gained a valuable entry point to Sudan at Kassala and by capturing Gallabat made it harder for the British to support the indigenous Ethiopian resistance fighters, the Arbegnoch (Patriots), in Gojjam. The loss of Kurmuk prompted some of the locals to resort to banditry; local Sudanese opinion was impressed by the Italian successes but the population of Kassala continued to support the British and supplied valuable information during the occupation. The SDF continued to operate close to Kassala and on 5 July, a company of the 2nd Battalion, Royal Warwickshire Regiment arrived at Gedaref; the British discovered that exaggerated rumours of the arrival had reached the Italians. Platt decided to bluff the Italians into believing that there were far greater forces on the Sudan border; an Italian map captured on 25 July showed that around 20,000 British and Sudanese troops were believed to be in Kassala province.^[4]

Italian plans

Kassala in 1940

After the conquest of British Somaliland, the Italians in the AOI adopted a more defensive posture. In late 1940, Italian forces had suffered defeats in the Mediterranean, the Western Desert, the Battle of Britain and in the Greco-Italian War. General Ugo Cavallero, the new Italian Chief of the General Staff in Rome, adopted a new strategy in East Africa. In December 1940, Cavallero ordered the Italian forces in East Africa to concentrate on the defence of the AOI by withdrawing to better defensive positions.^[6][7] On 31 December, Frusci ordered a retirement from the area north of Kassala along the track east of Sabdaret with outposts at Serobatib and Adaret, with a mobile force at Sabdaret as a reserve.^[6]

Earlier in the month, Frusci had received orders from Rome to cancel plans to invade Sudan, withdraw from Kassala and Metemma in the lowlands along the Sudan–Eritrea border and hold the more easily defended mountain passes on the Kassala–Agordat and Metemma–Gondar roads. Frusci was reluctant to withdraw from the lowlands, because it would be a propaganda defeat after he had announced that the British were about to attack and would be defeated. Kassala was also an important railway junction; holding it prevented the British from using the railway to carry supplies from Port Sudan on the Red Sea coast to the base at Gedaref.^[6]

British plans

In November 1940, Gazelle Force operated from the Gash river delta against Italian advanced posts around Kassala on the Ethiopian plateau, where hill ranges from 2,000–3,000 ft (610–910 m) bound wide valleys and the rainfall makes the area malarial from July to October.^[8] After a British reverse at Gallabat in November, Wavell held a review of the situation in Cairo from 1 to 2 December. With Compass imminent in Egypt, the British forces in East Africa were to provide help to the Patriots in Ethiopia and continue to pressure the Italians at Gallabat. Kassala was to be recaptured early in January 1941, to prevent an Italian advance deeper into Sudan and the 4th Indian Infantry Division (Major-General Noel Beresford-Peirse) was to be transferred from Egypt to Sudan from the end of December. With the success of Compass, East Africa was made second in importance after Egypt, a strategy in which victory over the Italian forces in Ethiopia was to be achieved by April 1941.^[9]

The transfer of the 4th Indian Division took until early January 1941. Platt intended to begin the offensive on the northern front on 8 February, with a pincer attack on Kassala, by the 4th Indian Infantry Division and 5th Indian Infantry Division (Major-General Lewis Heath), less a brigade each.^[10] News of the Italian disaster in Egypt, the harassment by Gazelle Force and the activities of Mission 101 in Ethiopia, led to the Italians withdrawing their northern flank to Keru and Wachai and then on 18 January to retreat hurriedly from Kassala, Tessenei and the triangle of Keru, Biscia and Aicota. Wavell ordered Platt to begin the March offensive early on 9 February and to begin on 19 January, when it seemed that Italian morale was crumbling. Wireless decrypts greatly aided British preparations and the decision to attack ahead of schedule.^[11] The Italian withdrawal led Wavell to order a pursuit and the troops arriving at Port Sudan (Briggs Force) to attack at Karora and advance parallel to the coast, to meet the forces coming from the west.^[12][10]

Italian retirement

The situation in late 1940 rendered the Sudanese towns of Kassala and Gallabat untenable, leading to the decision by Italian command to abandon them and withdraw the troops to Ethiopia and Eritrea. The Italian 12th Colonial Brigade (General Orlando Lorenzini) at Kassala retired on the night of 17/18 January 1941, which to the British suggested that the situation in Egypt was affecting Italian strategy in East Africa and that a bolder British policy was justified. The British offensive from Sudan due on 9 February was brought forward to 19 January and Platt was ordered to mount a vigorous pursuit.^[10] While the garrison of Gallabat was ordered to reach Gondar, the 12th Colonial Brigade methodically retired towards the Keru–Biscia–Aicota triangle in the foothills of the Eritrean highlands, while opposing some resistance to Gazelle Force (Colonel Frank Messervy) a motorised unit from the SDF, the 4th and the 5th Indian Infantry divisions.^[13]

As Gazelle Force threatened to outflank and encircle the retreating Italian forces, the Amhara Cavalry (Lieutenant Amedeo Guillet), was ordered to slow down the Allied advance for at least 24 hours in the plain between Aicota and Barentu in Eritrea. The cavalry covertly circumvented the Anglo-Indian forces and at dawn on 21 January, began a surprise cavalry charge from their rear. The charge created much disarray between the Commonwealth lines but as the cavalry prepared to charge again, the Allied force re-organized and opened fire on the Amhara cavalry, while armoured units tried to encircle them. Guillet's deputy, Lieutenant Renato Togni, charged a column of Matilda tanks with his platoon of 30 colonial soldiers who were all killed but this allowed the remainder of the cavalry to disengage. The charge cost the Amhara cavalry some 800 killed or wounded but slowed the British advance for long enough for the main Italian force to reach Agordat.^[14]

Agordat

The ground at Agordat was a natural defensive position and the defences mostly blocked an advance from the south-west from Biscia and Barentu; the northern flank was barred by the bed of the Baraka river.^[9] Two roads from Kassala ran to Agordat, a track to the north through Keru and Biscia, where the road improved and the Via Imperiale, a tarmac road through Tessenei, Aicota and Barentu. The roads joined at Agordat and went through Keren, the only route to Asmara. Agordat was a small town on the north bank of the Baraka river, a dry strand except in the rainy season, with palm groves along the banks. To the south-west of Agordat, was the Laquetat ridge, defended by a fort at each end, wire entanglements and a concrete wall. To the south-east, the Italians had built fortifications on four rocky outcrops and beyond was Mount Cochen, with a peak about 2,000 ft (610 m) above the plain.^[15]

To the north and east the foothills were closer together and the Barentu road ran south between Laquetat and Mt Cochen.^[15] The 4th Indian Division was sent 40 mi (64 km) along the road to Sabderat and Wachai, thence as far towards Keru as supplies allowed, with the Matilda Infantry tanks of B Squadron, 4th RTR to join from Egypt. The 5th Indian Division was to capture Aicota, ready to move east to Barentu or north-east to Biscia. Apart from air attacks the pursuit was not opposed until Keru Gorge, which was held by a rearguard of the 41st Colonial Brigade. The brigade retreated on the night of 22/23 January, leaving General Ugo Fongoli, his staff and 800 men behind as prisoners.^[16] By 25 January, the Allied forces had cut the line of communication between Agordat and Barentu. On the following day, the 4th Indian Division (5th Indian Infantry Brigade and 11th Indian Infantry Brigade) artillery bombarded the Italian defences, while South African Air Force (SAAF) Hawker Hurricane fighters destroyed most of the fifty Italian aircraft in Asmara and Gura, achieving air supremacy for the rest of the campaign. By 27 January, most of the two Indian divisions were close to Agordat and a brigade turned south, to move across country towards Barentu.^[17]

28–30 January

On 28 January, The 4th Indian Division made an outflanking move north of Agordat towards Mount Itaberrè and Mount Caianac and Four Matilda I tanks of the 7th RTR arrived during the day. The 4th Battalion, Sikh Regiment and the 3/1st Battalion, 1st Punjab Regiment closed on Laquetat unopposed. The 3/14th Punjab made a cautious advance over the plain and reached the top of Mt Cochen just after dark. The 2nd Battalion, Queen's Own Cameron Highlanders and 1st Battalion (Wellesley's), 6th Rajputana Rifles followed up across the plain and by dark had dug in on the Italian flank. The 4th Sikh and 3/2st Punjab attacked Laquetat ridge during the night of 28/29 January but were repulsed and were transferred back to the plain, Gazelle Force taking over. Two Italian battalions had been sent to reinforce Mt Cochen during the night and the fighting continued all through 29 January. The 1st Battalion, (Wellesley's) moved up to the ridge but on 30 January, three more Italian battalions arrived and counter-attacked, throwing back the Indian infantry. A company from each of the Indian battalions had been detached because of insufficient mules and carried ammunition, water and food forward by hand, assisted by the Bengal Sappers and Miners. During the supply effort the carriers had to drop their loads and fix bayonets, to fill a gap in the line. The Italians also managed to get some pack artillery behind Mt Cochen, which forced the attackers to withdraw and reorganise the two Indian battalions which had become dispersed among the ridge and ravines. Three Indian battalions attacked again and forced the Italians back towards the Barentu road. In the plain, the 2nd Cameron eventually captured a spur known as Gibraltar and defeated several Italian counter-attacks during the afternoon. ^[18]

31 January

The attack on Mount Laquatat and the pass between Mount Laquatat and Mount Cochen (where the defenders were commanded by Colonel Luziani) was renewed by the 1st Battalion, Royal Fusiliers behind the four Matildas, to break through the last obstacle before the Agordat plain.^[19] The final assault took place from 11:00 a.m. – 2:00 p.m. with the Anglo-Indian infantry preceded by Matilda tanks which crushed the Italian defences within a few minutes, overwhelmed the Italian artillery and destroyed eleven M11/39 tanks and Fiat L3 tankettes, some of which were crewed by German volunteers from ships in the port of Massawa.^[20]

Several counter-attacks by the Askari and the Amhara Cavalry in the open failed and the 3/1st Punjab passed through the Fusiliers to attack four fortified hills, known as Tinker, Tailor, Soldier and Sailor. Tinker and Tailor had been captured as night fell and the Punjabis dug in to face Italian counter-attacks but these did not occur. Apprehensive of being trapped if the Keren road was cut behind them, the defenders retreated in some confusion towards Keren, while the Indian and British infantry pursued towards Agordat. The British took 1,000 prisoners along with 14 damaged tanks, 43 guns and all the heavy equipment.^[21] During the pursuit, another 1,000 prisoners were taken and Agordat was occupied on 1 February.^[20]

Barentu

United Nations map of Eritrea

Barentu was a fortified town with an airfield, in a plain ringed with steep hills, about 28 mi (45 km) from a gold mine at Guala. The town was garrisoned by the 2nd Colonial Division (General Angelo Bergonzi) with nine infantry battalions (8,000 men) 36 tanks and armoured cars and 32 mountain guns in three defence lines. On 21 January, the 29th Indian Infantry Brigade advanced from Aicota (now Haykota) and was opposed by an Italian Colonial brigade on the Barentu road, until the defenders were outflanked by the 6th Battalion, 13th Frontier Force Rifles (6th FFR).^[22]

On the evening of 25 January another rearguard was encountered; an attack before dawn was repulsed after the 3rd Battalion, 2nd Punjab Regiment captured its objective but the 1st Battalion, Worcestershire Regiment got lost in the dark, leaving the flank of the 6th FFR uncovered and the defenders counter-attacked. Another effort on 26 January made some progress and the Italians retired during the night. On 28 January, the Indians attacked another blocking position and forced the Italians back to a position 6 mi (9.7 km) from Barentu, where the defenders resisted for three days.^[22]

The 10th Indian Infantry Brigade, advancing south from Agordat, found that rock and huge boulders on the slopes above the road had been dynamited to block the road. The defenders fought another determined rearguard action as the Indian engineers cleared the obstructions. On 31 January, the 1st Worcester captured rises to the west, despite stifling heat, thirst, moving through thorn bushes which tore clothing and slashed skin, over dry crumbly soil. The Italians were forced out of two lines of defence but had prepared for this and surveyed their positions to bring mortar and machine-gun fire on them, forcing back the 1st Worcester and nearby Indian troops.^[23]

A SDF machine-gun company found a track and was able to outflank the defenders and attack from the east. As news spread of the fall of Agordat, the garrison withdrew along tracks towards Adi Ugri and along the Asmara–Adua road on the night of 1/2 February, leaving behind about two battalions' worth of men to be taken prisoner, along with their guns and several medium and light tanks. The first British and Indian troops into Barentu found hot food in the Italian field kitchens.^[23] The retreat of the remains of the 2nd Colonial Division was pursued by 2 Motor-Machine-Gun Group and by 8 February, the Italians had abandoned their vehicles and dispersed into the hills.^[16]

Analysis

Italian M11/39 tanks captured after the battle of Agordat

In two weeks the British had advanced 130 mi (210 km), fought four actions, taken 6,000 prisoners and 80 guns, 26 tanks and 400 lorries. A message from the Duke of Aosta was found in which ordered Agordat and Barentu to be defended to the last man, because the terrain would nullify British superiority in tanks and wheeled vehicles.^[24] The defenders had retreated instead and the British realised that the rest of the Italian force in Eritrea was still well-equipped, when 300 rifles, thousands of rounds of ammunition and hand grenades were recovered.^[25] The Italian and colonial defenders of Agordat had fought a determined defence but Lorenzini had kept the 42nd Brigade south of the Baraka (Barka River) and neglected the opportunity to send it to counter-attack around the northern flank of the attackers.^[24]

The British forces had been forced to stop their pursuit on the Barka, where the only bridge had been blown and Land mines laid in the river bed. The Italian retreats had been fairly well organised and though the British followed up as swiftly as possible, they lacked mobility; air support from the RAF was limited by the distance of their airfields from the front line. The airfields of the Regia Aeronautica at Sabderat and Tessenei were taken over as soon as possible and air attacks made on Italian marching columns, the railway and the remaining Italian airfields in Eritrea. From mid-January to mid-February, the Regia Aeronautica lost 61 aircraft, 50 in combat or on the ground.^[24] After the delaying action at Agordat, the 4th Colonial Division had time to retreat along a path to the north, sowing mines and demolitions as it went. On 3 February, Wavell ordered Platt to capture Keren and Asmara.^[26]

Casualties

During the battle and retirement from Agordat, 1,500 to 2,000 Italian and local troops were taken prisoner.^[27][20] From Agordat, Barentù and the retreat to Keren, Italian and colonial forces suffered casualties of 179 officers, 130 non-commissioned officers (NCOs), 1,230 Italian and 14,686 Askari other ranks; a total of 15,916 soldiers. The Italians lost 96 guns, 231 machine guns, 329 automatic rifles, 4,331 draught animals, 387 vehicles, 36 M11/39 tanks and L3 tankettes.^{[28][lower-alpha 2]} In 2014 Angelo Del Boca wrote that 1,289 Italian troops were killed around Gondar from June 1940 to the end of the campaign, 407 of the casualties being suffered in November 1941.^[28]
