I first learned about them as an insomniatic youth, watching The Fighting Sullivans (1944) on television in the middle of the night.
It's interesting for a war movie, in that almost all of the movie concentrates on the boys as they grow up together and become young men.
The deaths of the Sullivans partly inspired "Saving Private Ryan," and is the subject of the song "Sullivan" by the band Caroline's Spine. The band was offered a chance to play the song on the U.S.S. Enterprise in 1998.
Finally, there's a Sullivan Brothers Iowa Veterans Museum in Waterloo, Iowa.
"we regret to inform you that all your sons have passed away...all five, five, five...change your blue stars to gold"
Thank you and, yes, I had those same shivers down my spine in Nassau that morning. I threw the boat a salute when she shoved off and a couple of the yuppies on deck with me looked at me a bit strangely and moved away.
