Re: Saat baar looti gai Dilli
Perhaps Lahore was spared becuase of its fortifications, even before the Mughal fort which dominates the City today, the terrain around Lahore is better suited to defence. Just North of Lahore the area is perfect guerilla warfare country. Also the people of the region were perhaps more war-like and surrounded by equally frugal and tough people who worked together. I know that Jats, Rajputs, Ghakars etc while they had thier differences they came together much more cohesively.
Problem with Delhi is its too big to defend easily. The Jumuna river can easily be crossed most of the year becuase there are several ferry points and natural fords. The people of the Delhi plains are largely peacefull and I doubt any of them ever conducted raids on thier nieghbours... whereas Delhi was surrounded by not the friendliest of people and the tribes and nations that were around delhi never got along with each other either. Perhaps the other mistake was hoarding valuables inside the City of Delhi itlsef.
Lahore would normally have a treasury on the hills outside of the Town or in a small fortress just above the City on the Ravi side. Even when the Mughals came and built it as thier early capital they placed all the valuables like the treasure and palace gardens far from the city itself. They diverted the water to make obstacles as well as ornamental gardens. Also the City served as the old Mughal capital and its garrison was always well supplied.
Delhi is not so lucky despite being in a relatively fertile region the garrsons often ran out of food. Its not an easy city to defend for a small army and most of the defenders were never the best soldiers, when Aurangzeb sacked Delhi his brothers army was made up of citizens who were drafted in to fight in the difficuilt times. Whereas Auranzebs army were veterans from Southern Campaigns.
While Lahore lay on the GT road most invaders were cautious of its surounding territory which was always a wild west... whereas Delhi had little hope of relief armies ever coming to the rescue and since the terrain around Delhi is a relatively dusty flat plain... any approaching relief force can be seen for miles.
Lahore is lucky that from the North side there are valleys that could hide huge armies and even sustain such forces for long periods.
To effectively protect Delhi the defender would need a huge army but it would be very thinly spread on the perimeters. The only other big option almost all the defenders took was to fight an open battle outside the city. Problem with this tactic was that if the army ever lost... it was a battle for all or nothing.
Wheras an Army defending Lahore had much less perimeter wall to defend and even if it fought a battle outside the terrain allowed for a defending force to use several rearguard tactics... advancing between valleys for example with the flanks covered against cavalry... in the mediaval times Lahore had much more forest around it too.
Whereas Delhi was almost alwasy a plain from at least the 12th Century... it was perfect terrain for cavalry warfare and since most of the invaders used mobile cavalry as thier main weapon the defenders always ran the risk of being outflanked.
Thus Delhi suffered badly in the long run... its a great tragedy really that many of the armies entrusted with protecting Delhi often were led by weak commanders and sometimes the generals were very cruel in that they chose to leave things to the last minute. A lot of the defending armies sometimes abandoned the city altogether choosing to pull back and find a position where it would be easier to defend.
The Tughlak Dynasty when it fought the Mongols used to just ride out and face them on the battlefields far to the North West of Delhi rather than risk siege warfare. Most besiegers could raid the countryside for food but the defenders static troops often starved becuase thier supplies were cut.
