Let me add a couple of qualifiers - Lets keep Brigadiers out of this inspite of their status - otherwise we will have to come up with a Top 300 'Generals' list.
Lets also add a line so that we know why the General deserves a mention here. My Revised List
from my 1947-48 List
Lt Gen Dudley Russell GOC Jak Force - For monitoring the Punjab Boundary Force and also the initial days in Kashmir.
Lt Gen KM Cariappa COAS(later Gen, Field Marshal) - For being the Army Commander and monitoring Kashmir after Russell left - and for having a handson experience on the situation.
Lt Gen SM Shri Nagesh GOC JAK Force - He was the 'Corps' Commander under Carriappa who was an Army Commander. he provided the resources for both the Sri and Ja Divisions.
Maj Gen Kalwant Singh GOC JAK Force - Initial days under Russell - he was the sole commander of the Indian Forces.
Maj Gen Atma Singh GOC Jammu Div - Sucessful ops at Rajauri, Poonch
Maj Gen KS Thimmayya GOC Sri Div - Tithwal offensive, Zoji La, Leh RElief..
Gen PN Thapar COAS - he got a <img src="http://www.bharat-rakshak.com/ubb/icons/icon13.gif" alt="" /> blamed for the soft approach on his generals - The buck stopped with him in 62.
Lt Gen LP Sen GOC-in-C Eastern Command - Exemplary record in WW2 and the 1947 Ops , Unexplainable conduct during 1962, though not directly blamed for the defeat, he was blamed for not sacking Kaul in the begining itself. Held responsible for succumbing to political pressure.
Lt Gen Daulat Singh GOC-in-C Western Command - Wonderful record in leading Western Command. No Major defeats in his area of ops
Lt Gen BM Kaul GOC 4 Corps - he got a <img src="http://www.bharat-rakshak.com/ubb/icons/icon13.gif" alt="" /> Blamed for all reverses in NEFA. Resigned after 62. Nehru's favourite general.
Lt Gen Bikram Singh GOC XV Corps - Great record in defending Ladakh, Chushul. Died in Heli crash, else he would have probably been chief instead of Manekshaw.
Lt Gen Harbaksh Singh GOC 4 Corps (Temp Command)- Temp replacement while Kaul reported sick. however moved to another corps when Kaul came back. he is credited with improving troop morale during the interim period.
Maj Gen Niranjan Prasad GOC 4 Div he got a <img src="http://www.bharat-rakshak.com/ubb/icons/icon13.gif" alt="" /> - Blamed for reverses and not standing up to kaul. Was sacked by Sen in 62 and later by Harbaksh in 65.
Maj Gen AS Pathania GOC 4 Div - he got a <img src="http://www.bharat-rakshak.com/ubb/icons/icon13.gif" alt="" /> MVC from 47 War. Replaced Prasad - poor planning in 62. Blamed for bad placement of his troops and subsequent withdrawal from Kameng.
Maj Gen MS Pathania GOC 2 Div - Cousin of above. No black marks, but did OK in Walong sector.
Between the periods 1947-62 even though the following were not involved in any conflicts - they are counted as Generals who made an impact.
Lt Gen SPP Thorat - GOC in C Eastern Command - came up with the original plans for defence against china - was sidelined when turn came for COAS promotion.
Gen Thimayya (again) - For heading the NNRC in Korea. Heading the Indian Army before 62. For standing up against Nehru (once) and resigning.
Lt Gen Umrao Singh - GOC 33 Corps - when Kaul was CGS. He resisted most of the plans thrusted on him from Delhi.
