Why not you check your own sources in PA? Better still The first attempt ended in failure. The second attempt, which is what this speaks about resulted in your posts being over run.
itsPakistan - Pakistan - History of Pakistan
On September 6, the 15th Infantry Division of the Indian Army, under World War II veteran Major General Prasad battled a massive counterattack by Pakistan near the west bank of the Ichhogil Canal (BRB Canal), which was a
de facto border of India and Pakistan. The General's entourage itself was ambushed and he was forced to flee his vehicle. A second, this time successful, attempt to cross over the Ichhogil Canal was made through the bridge in the village of Barki, just east of
Lahore. This brought the Indian Army within the range of Lahore International Airport.
Better still, why not call in

@fatman17 to clarify your doubt?
@Capt.Popeye @Joe Shearer (I wonder where he is, no history lessons nowadays)
By the way, there is a possibility of it being 18th Baloch. Since, these chaps had captured the Jonga of the Div Commander Major Gen Niranjan Prasad in the same sector. Above mentioned chaps please correct me, if I am mistaken.
Edit : Bloody hell! I gave a search for "Defence of Lahore" and all I got were real estate information!
