10th Indian Infantry Division

The Division was formed in January 1941, out of the 20th, 21st and 25th Indian Infantry Brigades. Commanded by Major General William "Bill" Slim, it landed in Basra in April, moving up the Euphrates and capturing Baghdad and the oilfields of Mosul as part of the Anglo-Iraqi War. When Iraq's ally Nazi Germany relocated its aircraft to Vichy French Syria, the 10th invaded Syria from Iraq in June. The 21st Brigade advanced towards Aleppo, while the 20th and 25th Brigades guarded the communication lines and the Mosul oilfield, respectively. Following the French surrender on 11 July, the division returned to guard duty in Mosul. In August, the division took part in the joint Anglo-Soviet invasion of Iran. At the conclusion of the Iranian operation, it returned to Iraq, where it underwent additional training and undertook security duties until May 1942.[2] In March 1942, command of the division passed from Slim to Major General Thomas "Pete" Rees when Slim was ordered to India to take command of Burma Corps, the kernel that would eventually become the British Fourteenth Army.[3]

Clement Attlee meets representatives of the 10th Indian Division, 1945.

We had scrambled thought skirmishes of the Iraq rebellion, been bloodied, but not too deeply, against the French in Syria, and enjoyed the unrestrainedly opéra bouffe of the invasion of Persia. We had bought our beer in Haifa and drunk it on the shores of the Caspian. We could move, we could fight, and we had begun to build up that most valuable of all assets a tradition of success. We had a good soldierly conceit of ourselves. Now in March 1942, in spite of dust storms ...it was stimulating to be in what we all felt was a critical spot, waiting for the threatened German invasion of Turkey.

The division then moved on to North Africa, reaching Halfaya Pass on 4 June to take part in the Western Desert Campaign.[5] Initially the 10th Indian Infantry Division was committed piecemeal with units involved at El Adem and Sidi Rezegh during the 1942 Battle of Gazala. In June the division, with the 2nd Free French Brigade under command, was ordered by Lieutenant General William Gott, the XIII Corps commander, to hold a position near the Egyptian border with Libya for 72 hours during the British Eighth Army's retreat to El Alamein. Major General Rees responded that the division had only just concentrated and that defensive works were as yet inadequate. He believed, therefore, that the division was unlikely to be able to withstand a full-scale attack from Erwin Rommel. Gott immediately visited Rees and relieved him of command of the division, telling him he lacked resolution.[6] During its retreat from Libya, the division was tasked with defending the coastal town of Mersa Matruh. In the ensuing battle it was overwhelmed and forced to retreat. 60% of the men evaded capture, reaching the Allied lines at El Alamein the following day. Most of the survivors were sent to the Nile Delta to recover. However, part of the division formed the improvised Robcol formation (comprising a regiment each of field artillery and light anti-aircraft artillery and a company of infantry), which held the Ruweisat Ridge between 2–3 July during the First Battle of El Alamein.[5]

In August, command passed to Major General Alan Bruce Blaxland while the division was sent to Cyprus with the responsibility of protecting the island. In July 1943, Major General Wilfrid Lewis Lloyd took command. In August, the 10th had relocated to the Middle East, now incorporating the 1st Greek Brigade, composed of royalist Greek and Yugoslavian troops along with the 20th and 25th Indian Brigades. During the summer it underwent training for a planned invasion of Rhodes, but the Allied defeat in the Dodecanese campaign put an end to those plans. In November it was placed on security duty in Lebanon. On 27 November, it began training for amphibious assault and mountain warfare in preparation for its role in the Italian Campaign.[7] In January 1944, Lloyd was killed in a car accident while overseeing a training exercise in Egypt; command passed to Major General Denys Whitehorn Reid.[8]

On 9 March 1944, the division was ordered to transfer to the Italian front. On 22 April, it relieved the 1st Canadian Division at the Ortona sector, which it held along with the 4th Indian Infantry Division. There it engaged in frequent patrols to prevent the enemy from sending reinforcement to the ongoing Battle of Monte Cassino. On 4 June, the division was moved to Venafro where it continued its training in mountain and urban warfare. The division returned to the front lines on 28 June, replacing the 8th Indian Infantry Division. Advancing through the Tiber valley, the division occupied Umbertide on 2 July. Taking advantage of its training in mountain warfare, it went on to take Città di Castello and Montone, infiltrating deep into Axis positions and striking from the flanks and the rear. By 1 August, the division's vanguard had reached the north of the Tiber river's basin. Further advance was blocked by the Alpe di Catenaia heights, a solid block of ridges and peaks that could only be taken by a set piece assault. On 4 August, troops belonging to the 10th Division captured Monte Altuccia; two days later the Regina height was occupied. It was abandoned as the division had to replace the 4th Indian Infantry Division on its former front line sector which spanned 15 miles (24 km). On 19 August, the Alpe di Catenaia heights were finally overtaken by the 3/1st Punjabis. On 17 September, the unit was transferred to the Adriatic in an effort to penetrate the Gothic Line.[9]

Numerous mountain battles and river crossings followed with Operation Olive on the Gothic Line and then Operation Grapeshot. The 10th Indian Infantry Division earned many battle honours and decorations and suffered many casualties before final victory in Italy and the end of World War II in Europe in May 1945. Security tasks on the Yugoslav border around Trieste completed the 10th Indian Division's war service.

The division was disbanded in January 1947; its last wartime commander, Major-General Reid, continuing to command it for the two years after the war.

The Indian Army's 10th Infantry Division was (re)established in 1965. It fought in the 1965 Indo-Pakistani War and possibly in 1971.

The new Indian Army's 20 Lancers (India) was raised again in July 1956 (confusingly, only about a month after Pakistan had re-raised their own 20th Lancers (Pakistan), on the other side of the confrontation line). The regiment was under command of the 10th Infantry Division during the 1965 war. Pakistan's surprise attack on 1 September, Operation Grand Slam, fell on 191 Infantry Brigade which was supported by 'C' Squadron, 20 Lancers, under Major Bhaskar Roy. The armoured attack comprised two regiments of medium tanks, M48 Pattons and M-36 Sherman B-2 tank destroyers.[11] The attack began at 0805 hours and was strongly resisted. During the initial phases of the attack, Roy destroyed 6 Pattons, 3 recoilless guns and captured a jeep. A second Pakistani armour attack was launched at 1100 hours and contested by the AMX-13s of 20 Lancers, which despite being outgunned and outnumbered, destroyed a total of 13 tanks and prevented the encirclement of 191 Infantry Brigade.[12] The regiment later fought in the defence of Jaurian under 41 Infantry Brigade.[13] For the defense of Chhamb-Jaurian, the regiment was awarded a theatre honour and Major Roy was awarded the Maha Vir Chakra for his leadership in this action.[12]

In addition to those listed above the following brigades were assigned or attached to the division for relatively short times during World War II.[16]
