Alternate History AHC: Britain raised an Army of 4 million infantrymen from India (or other colonies) to fight in Europe in 1917-1918?

What if Britain raised an Army of 4 million infantrymen from India from 1917-1918 for fighting in Europe, and mobilized Indian resources to support it as much as possible with cargo shipping, small arms, pack animals and supplies sourced from India?

[Please don't educate me on the 10s or 100s of thousands of Indians and other colonial troops that actually were used by Britain in the Great War, I am talking about a hypothetical 4 million *more*. Mentioning real history in this context as if it is brilliant insight adds nothing but pedantry.]

The round figure of 4 million, and 1917-1918 is deliberately chosen, to provide an Army that numerically and materially can substitute for the historical American Expeditionary Forces en.wikipedia.org/wiki/American_Expeditionary_Forces#Casualties , if need be.

How is it done? What does it cost? What are the postwar consequences?

In the "how is done?" category, how much of it can be recruited from India's population of 259 million (1914) through volunteers and incentives of pay, benefits, and bonuses? Would conscription be required to get to the numbers I am discussing?

Could the Indian economy be mobilized to manufacture adequate small arms and ammunition for this number of men? What about cargo shipping? What about the agricultural surplus to feed them? At what cost to other sectors of Indian economy?

Strictly speaking, the British wouldn't have to limit recruiting/conscription supply for this massive host the Imperial Expeditionary Force, from only India, I just went after India first because it is the biggest manpower pot at 259 million. The British can draw from all non-white colonies if they wish - British Africa had another 52 million, other British Asian colonies had 26 million, and British West Indies contributed a modest 1.6 million.

What social and political changes would such a massive mobilization effort cause to the internal structure of the individual colonies and empire?

I expect they would create demands, irresistible by the 20s or early 30s at latest, for an imperial federation of equal self-governing units, independence of major colonies, or create a major class division in the colonies between a praetorian caste with imperial service records and certain rights and privileges and natives without any. That's if the whole scheme does not just blow up in wartime itself, or immediately upon armistice - which I suppose we cannot rule out.

Since any such imperial policy would be decided and guided by the British Cabinet, it does not really have to wait until 1917. Could the British Empire harness its colonial manpower once it can really tell what it's in for (1915, with the Gallipoli fail and Russia fails; 1916, with Verdun, the Somme, and Kut) to achieve the win in the Great War within an 18 or 20 month span from go-time?

And what about the French with their colonial manpower?

Their colonial empire had about 65 million people in it as of 1914. In OTL, about 500,000, mostly Algerians, Moroccans, and Senegalese fought in WWI. But by the end of the war they were planning on drastic expansion in use of Sub-Saharan African troops?

What if the French had done mass voluntary or incentivized recruitment drives, or conscription from its nonwhite colonies a bit earlier in the war? Perhaps in reaction to the casualty shocks of the battles of 1914, or the failed Champagne offensive of 1915, or Verdun 1916? And if they stereotyped their colonial subjects less by nationality, and so freely recruited Sub-Saharan Africans besides Senegalese, and Indochinese troops, from an early point? I would imagine that would manifest in new strains on the French Colonial Empire by the 1920s.
 
You don't think small, do you?
:p
If there is a Will and Money few things - if any - are impossible. Saying that, raising a four million army from India (the colonies) inside three years if VERY difficult.
One issue is personel - you'd have to promote every 1914 Sepoy (IIRC not all literate) to a Naik. All pre war Naiks to Havildar or even Jemadar! And train thousands of Officers from amongst Indian monied classes. Hopefully the latter would speak English, hence the British instructers (where do you get them from?) do not have to learn Urdu first. And these Indians would have to be made Kings Commissioned Officers (of which pre-WWI there were half a dozen or so?) as there were not enough British Officers to go around, and not VCOs - thus destroying India as we know it. The impact on society and politics is mind boggling - new Martial Races, Indian Officers with Authority to order whities about ...
Would there be enough volunteers? Maybe ... but regardless if conscripts or volunteers you run into issues with Caste and language.
The other is equipment. There is no armaments industry in India to mobilise. It would have to be built from scratch. Even if you obtain the tooling, where do you get the engineers and foremen? What Castes should they come from? Forget about anything - besides some rifles and pistols - coming from Indian factories before 1918 (if not later). Look at the USA - starting from an infinitely higher level mastering voluminous rifle, artillery and MG production took America 3 years. Hence the weapons would have to come from established producers - the usual suspects in Europe plus Japan.
Shipping and food should be available. Taking 5M (counting OTL and ATL) men out of a population of 260M, even for a largely agricultural economy should not be too disruptive. That is "only" 4% or so of males. But I admit to be asspulling at this point :)

Out of curiosity: What was the combat effectiveness of colonial troops relative to European troops in World War I? Does anyone here have any data for this?
 
I think that this is the entire weapons industry of India at that time:

There would be repair workshop too, of course, and for artillery as well.
There is the Gun and Shell Factory at Cossipore, supposedly capable of making QF ordnance.

And speaking of the Goddess of War - in 1914 the Indian Army had 12 (saying - twelve) batteries of artillery. With British Officers, of course. A 4M army would provide - let us round down - what, 100 InfDiv? With 1200 (one thousand two hundred) batteries needed for the InfDiv alone?

A work around would be something like some OTL British Infantry Divisions which "lost" their UK raised Infantry Battalions and had them replaced with Indian troops. Example:
In other words, artillery and other elements requiring institutional knowledge and technically educated troops could come from Old Blighty. Yet the British Army needed 18-24 months to provide such (barebone level) for its expanded wartime army ...

Can Britain build more armament plants in India? Or would that be unnecessary since they can be built in Europe instead?

Haven't you read my first post?
Yes, it can. those plants will hit high volume production around 1920. Or more likely, in the early 20s.

That'd be much faster to achieve volume. And while you are at it - place (even larger than OTL?) orders in Japan.

What munitions and supply orders did the Entente make from Japan?

Handwaving away Japanese willingness and motive to participate, what is the largest ground force the Japanese could have sent to usefully participate in WWI battlefields, being a net contributor to the Entente side? I imagine if they were to deploy on the western front, their shipping/supply route should go through the Indian Ocean, Suez, Mediterranean, Riviera ports, through France and up to the front. Other European fronts (Italy, Salonica) are pretty much the same except for the endpoint.
 
IIRC at least 600,000 rifles, bought by Britain and Russia. I don't know if anything else. The top suspects (or candidates) would be field artillery as Japan was manufacturing a few types for itself and machine guns.

Ha!
Found something for you @raharris1973 :
In 1914, 120 guns were ordered by Russian Empire, converted to use 4.2-inch (107mm) Russian munitions for the 107 mm gun M1910. They received the designation 42-line quick-firing gun Model 1905. These guns continued service in the Soviet Red Army until World War II (there were still 88 such guns in 1936).

I would seriously doubt much field artillery from Japan would be considered up to scratch on the western front, considering American forces deployed there often dropped their organic artillery for French made artillery that was considered up to modern combat standard.
 
Well, there are other fronts then Western :p
Also - 1914-15 is not 1918.
Also, American artillery might had been crap?
And finally - WWI vintage Japanese artillery was mostly licensed Krupp or Schneider designs anyway ...
