Any details out there for this photo?

I love this photo. So much that I had a larger oil-on-canvas print made to hang in my office.
It's easy to find. Just search 'Marines in action at Belleau Wood'. I've never seen or read any details of the actual photo though, even though it appears in many an article every spring around the anniversary, such as this one...https://www.warhistoryonline.com/war...leau-wood.html

Maybe someone's google-fu is better than mine. What day of the battle, what unit were these guys from, etc., unless the details are all truly lost. It's my go-to spot on the wall to stare when I'm stuck on a hard problem.
