Your appreciation was inequitably distributed; CardSharp has access to records, data and to literature incomparably superior to mine. Some of the information he has reported as being available brought on an attack of irritable bowel syndrome, thankfully fairly short-lived.
The question of tactics in war is a on-going and evolving question and one that is very much dependent on circumstance. Is the study of that past war useful? Yes, Is the war likely to be fought in the same manner? No.
The bit in bold from CardSharp's comment can hardly be bettered as a caution against excessive study of the past, and as a guide to the useful study of the past, with a clear hint as to what is of importance.
Every general tends to fight the last war. Exceptions to this rule abound; those exceptions are what we know today as the Great Captains of history. Early Greek history is one source of useful study; as I have said before, my own personal favourite is neither Marathon nor Thermopylae, but Plataea, short, sharp and a brilliant illustration of Greek elan and fighting spirit in the face of a menacing but ill-disciplined throng. Remember that the charge by the Greeks across the Persian front was executed at a dead run, wearing the heavy Greek cuirass of the hoplite, and you will understand why it stirs the blood. And it was the same Greeks who cut up the Spartans on a lonely spit of sand and buried the legend of Spartan invincibility in battle once and for all. Finally, the hoplite was consigned to history with almost contemptuous ease by Epaminondas with his unbalanced phalanx, which formation ruled until a semi-barbarian king studied it carefully and devised a flexible formation of phalanx plus companions plus cavalry, the whole hinging on the companions, which could manouevre through the rather linear thinking of rival generals much like the unpredictable knight on a chessboard. This unlikely military thinker was Philip II of Macedon, and he was pretty much unbeatable, as was his son; his son made brilliant use of his new army formation to win some of the most sensational victories of ancient times, as well as to seem to have one which is increasingly in doubt. With the Romans, we had even more startling developments in the military field; leaving aside the the bickerings among the Romans and their cousins the Latins, the Punic campaigns are classics. Carrhae is still a byword for double envelopment.
I have mentioned the Greeks and Romans at some length because while, for an Indian, the record of the 62 campaign is ignominious, useful only to be studied and studied again, and used in our military training to ensure that this is never, ever repeated, as an amateur of military history, it was unusual in being an infantry campaign, innocent of air power or of armour, which in the year of our Lord 1962 was a pretty unusual circumstance. The PLA use of artillery and mortar fire was in no way alien to classic infantry doctrine, and its dictates of flanking and enfilading fire.
To me, the 62 was a classic campaign, inexplicably occurring in times which had far outgrown the technology used by either side in the campaign.
The way a battle is fought is dependent on the circumstances and reality of that moment in time and no two situations are likely to be the same and consequently no two wars will be fought in the same way. A new war between China and India (God forbid) will be dictated by new technology, new objectives on each side, and new/different levels of commitment from either side. These more than anything that happened in the past will affect the tactics in a future war than what has already gone before.
But if you are asking for a simple answer, my guess is that war will still be an infantry war, and the side that builds the most roads and have the most heavy lift capability gain the upper hand. And whoever gains air supremacy will dictate the pace of that war. Fighting will happen the valleys and much of the fighting will be for passes through the mountains.
Well, yes, rather; but history is said to repeat itself, and when it does so, it does so in very different tone and register. The first tragic occurrence is said to repeat itself as farce. God forbid, but there are signals which tend to the farcical.
Returning to CardSharp's comments, if we look at the entire sweep of the topology of Indian borders, we have the following scenario:
- China: Aksai Chin and North West Tibet (military district Lanzhou): Infantry, artillery, armour, tactical air power, theatre air power;
[*]China: Himachal and Uttaranchal, and South West Tibet (military district Lanzhou): Infantry, mountain artillery, (possibly) tactical air power, theatre air power;
---------------------------------------------------------------------
- China: Uttar Pradesh, Southern Tibet through Nepal (military district Chengdu): Infantry, artillery, armour, tactical air power, theatre air power;
[*]China: West Bengal, Sikkim, Bhutan, Southern Tibet through Bhutan (military district Chengdu): Infantry, mountain artillery, (possibly) tactical air power, theatre air power;
[*]China: Arunachal West, Southern Tibet (military district Chengdu): Infantry, mountain artillery, (possibly) tactical air power, theatre air power;
[*]China: Arunachal East, Southern Tibet (military district Chengdu): mountain artillery, (possibly) tactical air power, theatre air power;
[*]China: Arunachal East, Southern Tibet through Myanmar (military district Chengdu): mountain artillery, (possibly) tactical air power, theatre air power;
This will explain why CardSharp says what he does: that a future India-China conflict, one that should never happen, will be fought as an infantry battle, unless the PRC decides to escalate on a major scale; it will be won by the side that has the better infrastructure, including roads; it will depend on the intelligent use of heavy air-lift and rail logistics capabilities.
Rather unpleasant reading for any Indian.
We can deal separately with the question of why fighting is likely to be restricted to the hills and mountains, and therefore the PLA is unlikely to outrun its lines of communications and of supplies.
We can also deal separately with the vexed question of air-power and its role: does close air support really have much to do in the mountains?
Depending on whether a country adopts an offensive doctrine or Scorched earth doctrine.
India, I think, historically adopted scorched earth against China and now I think adopts an offensive one. I'm not very informed though.
Some facts to consider: The last encounter between Indians and trans-Himalayan soldiers was between the Dogra expeditionary force led personally by Zorawar Singh. On that occasion, the Dogras were faced by a scorched earth policy themselves.
More soon.
