1916 letter: Redmond’s volunteers were not all nationalists

This is the assertion that the great majority of the 150,000 members of the National Volunteers loyal to John Redmond rejected the call of a minority to oppose the war and enlisted in the British Army to fight in 1914-18.
But according to the undisputed official figures - repeated on the website of the Department of the Taoiseach - a total of just over 28,000 national volunteers joined the British Army throughout the entire war. That was about 20% of its membership at the time.
