I found this verse in a book about life in County Down in the interwar period.  The author’s family sang what he said was an Old Music Hall song.

It went

We don’t want to fight

but by Jingo if we do

We won’t go to the Front ourselves

We’ll send the Old Hindoo

Hayes, M. (1996) Black Pudding with Slim Belfast: Blackstaff p.183

The version of the song from the 1878 I have seen (Written by G.W Hunt, https://monologues.co.uk/musichall/Songs-W/We-Dont-Want-To-Fight.htm

performed by  Gilbert Hastings MacDermott http://www.victorianweb.org/mt/musichall/macdermott1.html)  , doesn’t include the line about the Hindoo. Any idea about who wrote or performed this version and when?

Best wishes
