It played a part in the wartime exhaustion. Just having the sniffles drops people's performance.
Also it is acknowledged superinfection killed most people not the flu itself. So were they victim of the flu, or the superinfection they suffered from? They had a compromised immune system to begin with, bad hygiene and malnourishment both in the trenches and back at home tired out people which allowed infection of all kinds. The flu itself was more aggressive tho, we know from the example from countries not at war, like Spain.
