THE BATTLE OF PRATAPGARH (10 Nov, 1659)

Chhatrapati Shivaji Maharaj's impeccable military genius and matchless courage humbled the Adil Shahi Sultanate.

The beginning of what was to come later for the M0ghuls from one of the most indefatigable defenders of Dharma!

(Thread)

Shivaji’s growing influence in Maval region, made him a threat to the Adil Shahi ruler of Bijapur who sought to restrain him. The man who was given the responsibility of this mission, was their commander, Afzal Khan. Afzal was a formidable warrior known for his ruthlessness.(1)

His strategy was to bring Shivaji out into the plains, where he held an advantage, compared to the rocky Deccan terrain. Afzal attacked the holy town of Pandharpur, and later demolished the temple of Bhavani at Tuljapur to instigate Shivaji in a bid to bring him out.(2)

Shivaji was angry but remained patient. Knowing that he could not defeat Bijapuri Sultanate in an open battle, Shivaji moved to Pratapgarh fort, located on rocky heights, surrounded by thick forests of Jawali.(3)

This set the pattern for future Maratha attacks, using guerrilla warfare against larger invading armies rendering them ineffective in unfavorable terrain.(4)

In regards to the #CapitolCoup, I’m in a unique position. I monitored forums ahead of time and then was present for the coup itself.

These are my observations based on what I saw and the evidence that’s been collected so far. I reserve the right to adjust my analysis as needed.

Let’s talk about the organization of the coup first. Seeing some people insist that the coup must have been highly planned and coordinated.

Yes and no. This was a #StochasticCoup. We’ll see little evidence of direct communication between Trump and the insurrectionists.

Within the insurrectionists, there was not one group that executed the storming of the Capitol.

Rather, there were a number of smaller groups working independently towards the same goal. I expect you’ll see little evidence that these various groups communicated with each other.

What you will see is detailed planning and coordination within these small groups.

Then there were the joyriders, those Trump supporters who weren’t directly involved in any plotting but who were more than happy to go along for the ride once the coup was in motion.

After four years, the insurrectionists were carefully attuned to Trump’s messaging.

Every tweet and statement of his was treated as marching orders and carefully dissected for meaning.

It’s why shutting down Trump’s Twitter account was so important.

1 There's a chasm between an NLP technology that works well in the research lab and something that works for applications that real people use. This was eye-opening when I started my career, and every time I talk to an NLP engineer at @textio, it continues to strike me even now.

2 Research conditions are theoretical and/or idealized. A huge problem for so-called NLP or AI startups with highly credentialed academic founders is that they bring limited knowledge of what it takes to build real products outside the lab.

3 A product is ultimately a thing that people pay for - not just cool technology or user experience. But I’m not even talking about knowledge gaps in go-to-market work. I'm talking purely technical gaps: how you go from science project to performant + delightful user experience.

4 Most commoditized NLP packages solve well-understood problems in standard ways that sacrifice either precision or performance. In a research lab, this is not usually a hard trade-off; in general, no one is using what you make, so performance is less important than precision.

5 In software, when you’re making something for real people to use, these tradeoffs are a big deal. Especially if you’re asking those people to pay for what you’ve made (can’t get away from that pesky GTM thinking). They expect quality, which includes precision AND performance.

A long but must read thread. Udaybhan Rathore and myth making in Maratha history: An analysis. This is the thread on Udaybhan Rathore, who he was and how over the time period, his life was portrayed in maratha chronicles and pseudo history. (1/n)

Udaybhan rathore was the head of Bhinai thikana (84 villages) in Ajmer. He was the direct descendant of the famous Rao Chandrasen, Raja of Marwar (4th generation) who resisted Akbar all his life and never made any alliance with mughals like Maharana Pratap. (2/n)

Later in 1783, Maharaja of Jodhpur gave title of Raja to Bhinai family for their military service. Bhinai family and their direct descendant Raja Sh Mayuraj Singh still lives in Ajmer. Anyway coming to Udaybhan Rathore and story of Tanaji. (3/n)

Jai Singh's march on Shivaji and treaty of Purandar (1665) is a well known episode to repeat here. After getting the hill forts from Shivaji under the treaty, Jai Singh didn't have enough man-power to man every one of the small forts because of his next (4/n)

campaign against Bijapur. Jai Singh personally took over a couple of important forts like Kondhana (Sinhgarh), Purandar etc. Others were given to some mughals or their fortification walls destroyed. Jai Singh died in 1667 near Burhanpur while enroute to the north. (5/n)
