The 1st South African Infantry Division was an infantry division of the army of the Union of South Africa. During World War II the division served in East Africa from 1940 to 1941 and in the Western Desert Campaign from 1941 to 1942. The division was disbanded on 1 January 1943, for conversion into what would become the 6th South African Armoured Division. The division was also briefly active after the war from 1 July 1948 to 1 November 1949.South African Defence Review via http://www.rhodesia.nl/sadfhist.htm

Outbreak of war When Neville Chamberlain declared war on 3 September 1939, the Union Defence Force consisted of 5,385 Permanent Force members, 14,631 Citizen Force members and 122,000 Commandos of which only 39,000 were considered suited for field deployment. The Defence Act also prohibited the deployment of its members beyond the confines of southern Africa On 4 September, General Hertzog resigned and was replaced by General Smuts and two days later, on 6 September South Africa declared war against Germany.

The "phoney war" luckily granted more time and by 22 September a policy paper had been submitted calling for the formation of two "Forces" and was approved in mid October, laying the foundations for the formation of 1 and 2 SA Divisions. In March 1941, fearing the Italian commitment to war, General Wavell requested the services of a South African Brigade Group in Kenya via the Imperial General Staff. Prime Minister Smuts consented.

Initially, to circumvent the limitations of the South African Defence Act (Act No 13 of 1912), only volunteers were recruited and they were subject to an oath on induction whereby they consented to being deployed anywhere in Africa, this being a pre-requisite for acceptance into the Union forces. Men who attested under these terms were entitled to wear the distinct insignia of the Mobile Field Force, a red / orange shoulder strap which was to become known as the "Red Tab". The Defence Act was later amended.

Advance party to East Africa The formation of the 1st South Africa Infantry Brigade Group was approved on 13 May 1940. Although approved, South Africa was desperately short of equipment and had few armoured vehiclesBirkby p. 166 save for a limited number of locally designed prototype armoured cars.The Marmon-Herrington Mk I Armoured Car. Officially known as South African Reconnaissance Car Mk 1. Also see World War II Database Marmon-Herrington Armored Car | World War II Database. Due to this limited infantry and armour offensive capacity, all that could initially be mobilised was an anti-aircraft detachment. Thus, part of the 1st SA Anti-Aircraft brigade, who arrived in Mombasa on 1 June 1940 as an advance party to protect Mombasa harbour from feared Italian air attacks,Playfair p. 180 becoming the first South African land forces to be deployed outside of South Africa since the First World War. On 10 June 1940, Italy declared war and on the next day South Africa officially declared war on Italy. Two hours after the South African declaration, four Ju 86's of the South African Air Force bombed Italian troops at a Banda Camp close to Moyale,12 Sqn SAAF a few kilometres across the Kenya border into Ethiopia.Orpen Vol. I, p. 10

1st Brigade Group Mobilised In order to rapidly provide forces to East Africa, as well as due to the lack of trained manpower it was decided to initially form a single Infantry Brigade from the 1st Duke of Edinburgh's Own Rifles, the 1st Royal Natal Carabineers and the 1st Transvaal Scottish with brigade artillery and support elements (Refer ORBAT below). On 13 July, the 1st South African Brigade Group under command of Colonel John Daniel was issued its movement order and it assembled at Zonderwater for the farewell parade, with General Smuts taking the salute ironically, that Sunday being celebrated as "Delville Wood Day".Orpen Vol. I, p. 16

Embarkation commenced in Durban the next day, with Brigade HQ, 1st Transvaal Scottish and attached troops boarding the MS Dilwara while the Royal Natal Carbineers and a number of voluntary aid nurses boarded the Devonshire. The Duke of Edinburgh's Own Rifles followed in the Rajula. The convoy cast off on 17 July 1940.Although officially part of 1st SA Div, the 1st SA Inf Brigade served most of its time in East Africa as an independent brigade, detached to formations other than 1st SA Division. For an account of the 1st Brigade actions in East Africa, see East African Campaign. It was only re-united with its parent formation in the Western Desert.

Establishment On 13 August 1940 the 1st South African Infantry Division was officially constituted consisting of the 1st SA Brigade Group already in Kenya and the 2nd and 5th South African Infantry Brigade Groups. Brig-Gen George Brink was appointed as commander with Lt. Col W.H.E. Poole as GSO 1.Orpen Vol. I, p. 50 The Division HQ landed at Mombasa on 11 November 1940.Orpen Vol. I, p. 61

2nd and 5th Brigades

Dominating the Dida Galgalla (Desert of the Night)

After the success of the 1st South African Infantry Brigade against the Italians at the El Wak border post on 16 December 1940, Lieutenant-General Alan Cunningham was intent on opening access into the Galla-Sidamo area across the Chalbi Desert by advancing eastwards from the eastern side of Lake Rudolf and to support a possible rebellion by the Shifta tribe against the Italians.Orpen I, p. 90 This was the first offensive to be assigned to 1 SA Division. The division then consisted of the 2nd and 5th SA Brigades (located at Marsabit), the 25th East African Brigade (at Lokitaung) as well as six companies of the 2nd Abyssinian Irregulars. Almost on a daily basis, division infantry and armoured cars crossed the Dida Galgalla in search of enemy patrols. The Italians maintained a well established outpost at Turbi Hills, from which they had clear observation of any vehicle or troop movements in the Dida Galgalla. From December 1940 to February 1941 patrols had never been able to engage Italian patrols or elements as they withdrew deeper into Abyssinia on sighting the South African patrols entering the Dida Galgalla, only to return the next day.Klein II, p. 110

El Yibo Before advancing into southern Abyssinia, General Brink was compelled to protect his western flank and to deny water sources to the Italians. For this reason, on 16 January the 1st Natal Mounted Rifles (of the 2nd Brigade), No 2 Armoured Car Company, 12 SA Field Battery and two irregular companies attacked the string of wells at El Yibo and El Sardu in the Kenyan Northern Frontier District. After three days of fighting, supported by the SAAF, the enemy withdrew from El Yibo on the night of 17 January and on the afternoon of 18 January, the 2nd Field Force Battalion, which had been moved up from the brigade reserve, entered an abandoned El Sardu. With the only water sources in the area in the hands of the South Africans, the advance into Abyssinia could commence.Klein II, p. 114

Gorai and Hobok

2nd and 5th Brigades crossed the Abyssinian border north of Dukana late afternoon on 31 January 1941, moving in parallel columns to assault the Italian positions in the Mega-Moyale complex.Mega: 9th Italian Brigade Group HQ, 2nd, 54th Colonial Infantry Battalion and 60th Colonial Infantry, 585th Blackshirt Battalion, 9th Pack Artillery Battery.Moyale: 2nd Italian Brigade HQ, 12th Colonial Infantry, 105th Blackshirt Battalion and the 25th Artillery Pack Battery.Klein II, p. 110 The Italians had well established and entrenched advance positions at Goai Crater, El Gumu and Hobok which were to be taken before the main forces at Mega-Moyale could be attacked. 2nd Brigade was assigned to attack Gorai on the right, while 5th Brigade was to assault El Gumu. The attack commenced early morning on 1 February and by 1600 both objectives had been secured. The armoured cars however failed to cut off the remnant Italian forces, and they retreated back towards Mega and Moyale. The next day, 3rd Transvaal Scottish and the armoured cars attacked Fort Hobok, sited on a ridge 30 km west of El Gumu supported by artillery. The armoured cars again covered the flanks and tried to cut off any retreating forces. By afternoon, the fort had been captured. The 2nd Brigade now held Gorai and the 5th Brigade, Hobok (Map 1: Point 1). It was again hoped that these raids would ignite the Shifta uprising, but as with the previous occasion, this never materialised.

Battle for Mega

Having two salients extending into Ethiopia, Cunningham and Brink decided to consolidate and to secure their lines of supply in face of the oncoming rainy season which would make the Chalbi desert impassable. The key to supply in the area were the towns of Mega and Moyale, overlooking the two major roads into Abyssinia from Kenya. These were to be taken in a two brigade assault, by first attacking Mega (Map 1: Point 2) and then Moyale (Map 1: Point 3).

The Italians inadvertently opened the offensive when one of their supply columns from Yavello drove into a 2nd Brigade detachment deployed to control the Yavello-Mega road. Poor defensive arrangements by the South Africans allowed the Italians and Banda (irregulars) to drive into the centre of the detachment. After much reactive manoeuvre and intervention by the armoured car company, the Italian supply column and supporting troops were destroyed. The South African positions now known to the Italians, they were attacked by a detachment of Italian light tanks on 16 February, which caused the armoured cars to flee westwards and allowed the tanks to descend on the unprotected infantry. After a brisk but fierce fire-fight, the Italian tanks returned to Mega, leaving the South African detachment dispersed and disorganised.Klein II, p. 115

This attack had compromised surprise – and the attack on Mega was now commenced in all urgency. The 1st SA Irish (Col. Dobbs) were tasked to take the ridges east of Mega fort while the 3rd Transvaal Scottish (Lt-Col. Walter Kirby) were to occupy the a series of hills west of the fort and were to advance in line with the SA Irish. 2nd Brigade was to launch a direct attack on the fort and the Mega defensive complex. Despite incoming artillery fire, the Irish and Scottish regiments advances progressed well – but there was no sign of the 2nd Brigade who had not yet crossed the start-line, threatening to undermine the planned attack. At noon, a torrential rainstorm erupted and a thick mist enveloped the heights around Mega and it became obvious that the fort would not be taken by nightfall. The next morning, cloud and mist prevented air support and the Irish and Scottish battalions restarted their advance. It was only after the third day that the 2nd Brigade managed to reach their designated start-line due to poor navigation and the failure to identify serious terrain obstacles on their line of advance during reconnaissance. Clear skies on the third day permitted a coordinated attack with air support, artillery and the two brigades attacking together leading to an Italian surrender late that afternoon (18 February).Klein II, p. 116

Mega fell with 1,000 Italian and African soldiers being captured on 22 February, and later that day one of the irregular companies attached to 2nd Brigade entered Moyale unopposed. The Italians had fled, leaving large quantities of logistical stores.Playfair p. 411 The division had attained its objective and had secured the access roads into southern Abyssinia before the onset of the seasonal rains.
