Wrong hill to die on???

Good morning

I was wondering if anyone knows about this saying ...
'wrong hill to die on'
I think it has a military meaning, but a friend of mine says she thinks that it means it is better to die on a mountain than a hill.
does anyone have any ideas??

thanks and have a wonderful day

I'll look in my military sayings reference tonight. My first reaction is that maybe it means the soldier died in an obscure battle. That there would have been more glory to dying on another hill.
