Air Superiority: Contested
D+14. Unseasonable storms roll across northeast Pakistan. The Pakistani army welcomes the reprieve, as the storms will ground most aircraft and slow India's drive on the southern front. However, the weather also grounds air transport, leaving the newly arrived infantry divisions of XII and XXXI Corps to make the slow trek north on foot.
The Pakistani counteroffensive out of Islamabad continues. In the pouring rain, X and XI Corps maul XVI Corps as it tries to retreat, destroying the 39/XVI Infantry Division. XVI Corps is now in danger of being cut off.
The four mountain infantry brigades of the FCNA complete their grueling hike back through the northwest pass out of the Kashmir Valley, and in conjunction with the 323/FCNA Mountain Infantry Brigade, destroy an Indian combat outpost. The mountain infantry brigades, battered after their unsuccessful foray into Kashmir, pause just inside the Indian border to replenish and receive reinforcements.
As Pakistan's XXXI and XII Corps move north, the mechanized elements of XXI, X, and XII Corps move into blocking positions to prevent them from moving east into Indian territory. Unfortunately for India, the storms prevent these units from moving into the marshland and cutting off the highway to Lahore.
In Kashmir, three brigades of mountain infantry deploy forward into fortifications to meet the looming threat of attack by Pakistan's X and XI Corps.
In the south, the infantry divisions of Pakistan's XII Corps slowly trundle north through the driving rain, while XXXI Corps—which had been initially tasked with relieving Lahore—takes up defensive positions in Pakpattan and Okara.
East of Islamabad, the final agony of India's XVI Corps begins. Successive hammer blows by X and XI Corps destroy the Indian 10/XVI Infantry Division, leaving the 25/XVI Infantry Division virtually surrounded on the west bank of the river. India now faces a serious dilemma, as the breakout of X and XI Corps could threaten either Kashmir or the offensive around Sialkot.
The 25/XVI Infantry Division withdraws across the river, but it fails to destroy the bridge.
Mechanized and armored elements of XXI and XI Corps assault Pakpattan. The defenders refuse to retreat, even in the face of serious casualties.
Storms hamper India's progress against Lahore, as units can’t enter the wetlands southeast of the city. X Corps, the 33/I Armored Division, 50th Paratrooper Brigade, and XI Corps proceed with an attack nonetheless, calling in heavy artillery support. The attack reduces the defending 14/II Infantry Division, but both infantry divisions of X Corps suffer casualties in return.
In the north, Sialkot continues to hold out. A renewed assault by II and IX Corps, with artillery support, reduces the 19/X Infantry Division.
Pakistan's XII Corps and 26/XXXI Mechanized Infantry Division inflict heavy casualties on XII Corps, which had set up in a blocking position north of the Pakpattan. The way is now open for XII Corps and the 26/XXXI Mechanized Infantry Division to lift the siege of Pakpattan.
Armored brigades from I, XXX, and XI Corps, along with the 1/II Armored Division and the reduced infantry divisions in Sialkot, attack India's IX Corps south of the city, but poor coordination among the various corps hampers the effort and the attack fails.
In the highlands east of Islamabad, X and XI Corps mop up what's left of the 25/XVI Infantry Division, completing the annihilation of XVI Corps. Besides two combat outposts, the route to either Sialkot or Kashmir is now open.
News of the capture of Pakpattan by X Corps and XXI Corps helps lifts the gloom that settled over India's leadership following the destruction of XVI Corps at the gates of Islamabad. X and XXI must now secure their gains before Pakistan's XII Corps and 26/XXXI Mechanized Infantry Division can counterattack.
East of Lahore, India shuffles in fresh units to continue the assault on the city. Despite heavy artillery support, the attack fails, and the 4/I Mechanized Infantry Brigade is reduced.
With the destruction of XVI Corps, II and IX Corps face the alarming prospect of being attacked on both their southern and northern flanks. The Indians renew their assault on Sialkot with a fervor born of desperation. The attack destroys the defending 9/X Infantry Division, but does not breach the city.
