I don't recall ever seeing anyone mock the soldiers at LBH.
Mock Custer, sure. It's a very old tradition to mock military leaders who make very bad decisions and get their soldiers wiped out. Especially when they're flamboyant and boastful.
What was unfair about the battle? US soldiers attacked an Indian village that was a lot larger than they realized and got clobbered. BTW, what exactly is a "fair battle," and how do you go about setting one up?
Also BTW, there were no POWs at LBH. All were killed on the field of battle.
I have heard LBH mocked all my life, including a famous song, humorous references in movies, TV shows, print and countless conversations.
I use the treatment of POWs to get people in conversation to realize that there were no POWs, that our American GIs were involved in a bloody battle aginst a brutal enemy, and that the soldiers died in service to our country.
