How many personnel from British colonies served with the British Armed Forces or separate colonial formations such as the British Indian Army or the King's African Rifles?
Also, any info on the total number of casualties sustained by British colonial forces, as well as the amount of materials provided by the colonies, would be greatly appreciated.
Ashley Jackson's 2006 The British Empire and the Second World War is a very solid text that would have these details. I have used the book in the past as a source but do not know the figures off the top of my head. Jackson's book should have all the stats.
