After reading several accounts, including the source I have been using so far, Major K. C. Praval’s Indian Army After Independence, it seemed that
@meghdut ‘s summary of Cloughley is the most economical. So it is presented here to take our narrative forward.
@meghdut has done a marvellous job condensing Cloughley, and I have only made minor grammatical or orthographic corrections in several places.
THE SIALKOT SECTOR
The Indian attack in the Sialkot sector began on the night of 7th September on two axes; the Jammu Sialkot road and a parallel route some 12 miles to the south east. I Corps consisted of following unit
(i) 26 Inf Division, advanced on the axis of Jammu Sialkot road via the border village of Suchtgarh. G Ahmed claims it consisted of 4 Inf. Bdes and 2 Armd. Regts.
(ii) 6 Mtn. Div on the southern axis , crossed border near the village of Charwa.
(iii) 1 Armd. Joined the advance on the first light of 8th September, crossing the border near Charwa moving SE towards Chawinda; consisting of 2 Armrd Bdes with two ARs each and a lorried Ind. Bde with 2 batts. But having exchanged one/two of it’s Centurion equipped Regts. With Sherman Regts. of 2 IAB was understrength.
In the opening stages of the battle Pak 1st Cops covered the Sialkot sector with 15 Inf.Div. consisting of 7 battalions in 4 Bdes. (24,101,104,115) with 25 Cav as Armd Regt and a good allocation of artillery. But there were problems, not the least of which was that 115 Bde was fighting in the Jassar area, where it was required to remain for the rest of the war. 101, Bde (19 Punjab, 13FF) was the only formation directly defending Sialkot, and was located astride the main road to Jammu where it faced the onslaught of the Indian 26 Div. 24 bde(2 punjab, 3 FF and 25 Cav) was between the border and Chawinda, which lies due east of an almost right-angled bend in the Sialkot-Lahore railway. 104 Bde, which consisted of a single battalion 9 Baluch, was in reserve in the area of Uggoke/Raipur, about four miles west of Sialkot. It seemed that in the Jammr/Sialkot sector the Indian army might be able to bring sufficient force to bear to carry the day and even win the war. India’s 1 Corps advanced with two Inf Divisions and an Armd. Division against a Pakistani Armd. Bde and a single Inf. Division that had fragmented and understrength fighting units, no cohesive defensive plan, and some leaders of dubious quality who were always under considerable pressure. India’s 1 Armd. Div was ready to exploit the advantage won by the infantry that preceded it. The way to west seemed open.
6 Armd division , consisting of the Guides Cav, 22nd Cav. 1st SP Regt. Of 25 pdr on tracked chassis, and 4 FF (in total a Bde of 80 tanks 12 guns and 700 infantry) was in leaguer around Kot daska, 15 miles SW of Sialkot and 30 miles west of border . Chawinda, where it was to win it’s spurs , was 20 miles away. The units moved quickly when it became apparent that the Indian invasion was taking place.
THE INDIAN THRUST ALONG THE MAIN SIALKOT ROAD
In the north 2 batts of India’s 26 ID crossed the border astride the Jammu-sialkot road at midnight on 7th September. They quickly overcame the outposts of the Sutlwj Rangers but were brought to a halt by 101 Bde and weight of PA artillery. According to Mankekar and Johri, the approaches to Sialkot ‘bristled with pill-boxes, bunkers and gun-emplacements’, the latter including ‘ three field and one medium artillery regts. one heavy battery and one heavy mortar regts’. A concentration of this number of guns and mortars would cover an area of 500/150 meters in which the weight of shells and mortar bombs from one round of fire from each equipment would be approximately two tons. It does indicate that PA artillery fire was substantial and effective.
26 div. managed to reach the village of Kalarawanda, about 3 miles west of the border, by the time of the cease fire . There was a massive effort on the part of the IA on the northern axis of the Sialkot front, but an advance of only 3 miles cannot be called satisfactory when one considers the numerical superiority of 26 div. the defence of Sialkot by 19 Punjab and 13 FF and their supporting gunners were effective.
CHAWINDA BATTLES
Also at about midnight of 7th , two bdes of India’s 6 mountain division crossed the border south of the 26 div. axis and occupied the villages of Maharajke and Charwa just inside Pakistan. The battalions in the assault were 4 Raj Rif, and 2/5 Gurkha rifles. They secured the firm base for the advance of 1 AD at first light. In fact although the armour came through as planned, the immediate border area was not secure for several days because
PA stay behind parties wreaked havoc by sniping and ambushing. The division’s 1 AB reached the village of Phillora and the line of the Sialkot-Lahore railway by 0900, but it’s right flank was exposed by the failure of 43 inf bde to move quickly enough to keep up. Explanations vary regarding the reasons for this, Johri claims there was a downpour which bogged down the vehicles, Verghese states the armour simply outran the wheeled vehicles, but whatever happened, the Armd Bde had no flank protection. Then a hastily assembled ad-hoc force under direct command of HQ 1 Corps Gujranwala , moved east quickly and stuck on 8 September. It forced the IA back to border where it remained for two days before advancing again.
The PA had three Armd. Regts. and three Inf.battalions, a mixture of units from 1st Armd.(6th?) and 24 Inf. Bde. India had two Armd. bde with two Regts. and an Inf. Battalion. Forces about equal strength had met in battle and one had been made to retreat. Unfortunately for PA, it had insufficient armour immediately available to strike a quick blow that would have destroyed the Indian armour which was, naturally , in some disarray,. Even Verghese claims that “1st Armoured division was hit….hard in the rib, because it dashed forward somewhat rashly”.
Both sides used the lull to regroup. The Indians rapidly regained balance and probed forward, while the Pakistanis brought up as many reinforcements as they could to match the preponderance of Indian armour, which was also being augumented. It was a desperate time for PA. they well knew IA still had reserves while almost every unit of PA ORBAT was already committed to the fight. 11 Cav arrived from Chhamb along with 4 Inf. Bde(14 Punjab and 6FF) not a minute too early to join ain defending the area against the Indian assault which began at first light of 11 September.
The Indians advanced on two axes, Charwa-Chawind and Kaloi-Pagowal. The battalion group advancing on the latter route was repulsed and forced to fall back to the Kaloi area. On the Chawinda axis, the Indians reached Phillora after a series of head-on tank and infantry battles in which the two sides slugged it out until dusk when 5 Jat(100 killed), 5/9 GR, elements of the Poona Horse, and 4 Horse took and held the village. Battles raged over the area until cease-fire. The Indians knew it was essential for them to take Chawinda; the Pakistanis knew that if they did, the ground between Lahore and Sialkot would open up for their further advance as there were no forces available for defence further west. On 12 Spetember the PA tried without success to retake Phillora and next day Indians tried to outflank Chawinda from the east but, in an impressive display of flexibility, PA moved 19 and 20 Lancers and 1 FF (of 1 Ad) to tis defence and the Indian advance was halted after fierce fighting. Gulzar Ahmed acknowledged that “It must be said to the credit of the Indian AArmy that they fought with commendable courage and determination on this day”. An attack against Chawind was planned on 14th but, in classic employment of good intelligence and efficient artillery, the PA located the FUP of the Garhwali battalion that was to lead the assault and brought fire down on it. The battalion was forced to withdraw and the attack did not take place.
On the night of 15/16 September the Indians again tried to outflank the main PA force, this time by pressing west to Jassoran, three miles due west of Chawinda, across the railway line, then south to cut off Chawinda from the rear. Once the village was isolated, the Indians considered it would fall. At first the advance went well, with Jassoran being occupied at about 1100 on the 16 by 8 Garhwali rifles, supported by 1 Sqdn of 2 Poona Horse. The infantry than turned south and managed to take the village of Buttar Dograndi, but their armour was engaged so heavily by PA AT weapons that it could not advance further. The battalion held out until 17th then was forced to withdraw to Jassoran. It had been impossible to reinforce the unit in order to continue the advance, but neither could the Pakistanis bring in enough force to mount a counter attack. Furthermore the PA artillery was running short of ammunition. By mid September the daily allocation of 155mm ammo was five rounds per gun! The embargo on Pakistan was taking effect.
In spite of ammo shortage and tank casualities, the PA regrouped and managed to clear the area west of Chawinda around the railway line on 18/19 September; but did not manage to fully retake the station at Alhar, the north side of which remained in Indian hands until the cease-fire. The PA planned Operation Wind Up for 19/20 September with the aim of outflanking the Indians and penetrating west to cut them off. But it was cancelled for various reasons.
