I am looking for copies of photographs relating to the 13th Battalion Cheshire Regiment who were raised in Port Sunlight in September 1914 and served in France from September 1915.

I would be grateful for any assistance.

Nick,
Have you googled, 13th Battalion Cheshire Regiment and clicked images?

Yes, it was the first thing that I did😀

Regimental museum, Chester. Birkenhead News will have photos of individuals if killed in action, perhaps group photos, though would be hard to find.
