Were there italians attached to british armies

[TD60]

This is the grave orf an italian soldier but with a "british" headstone".

Is there any special reasons he was burried with british soldiers ?

Were there some italians soldiers attached to british armies or some regiments

affected to british army corps ?

I wonder also why this is this kind of headstone.

When french soldiers are among british ones they have usually a cross

not a british headstone.

Why it is done differently here ? Because this is a memorial and not really a grave ?

Thanks for your comments.
