Todd Zink: Everyone brings up the Sullivan Brothers from--
Logan: From the Second World War.
Zink: World War II, yeah, yeah. And so I thought it was my responsibility to try to minimize what harm could possibly come to any two sets of brothers.
The story of the Sullivan brothers was turned into this movie called "The Fighting Sullivans," a heartbreaking account of how all five brothers died in 1942 after a Japanese submarine torpedoed their ship.
Logan: There's just something about that bond of family and the idea that, you know, two brothers might not come back that kinda kicks you in the gut.
Zink: Yeah, it does. I could see my own brother and I almost wanting the same thing though, I think, if we found ourselves in the same unit. We're that close. So, as hard as it is, I can kind of understand them to some extent.
Joshua Beans: They have to look at from the other side of the table and say, 'Well, if-- if they were to both die while they were over there then it'd look really bad on us. And their family would hate us.'
Zink: You know, they were very eloquent in front of me, but I still wasn't convinced that this, you know, having them together would be the right thing.
But Col. Zink had no idea what he was up against. The Beans brothers' family is steeped in Marine history. Their grandfather and great grandfather both rose to brigadier general. And the boys' father, Mark, was also a Marine.
Zink: I told 'em I couldn't face their mother if they were both lost, you know. And almost on cue, they presented a letter from their parents.
In the letter, Mark and his wife, Crystal, wrote, "We understand... that both our sons could be lost or injured at the same time but we would rather know that the two of them are together regardless of what happens."
Logan: Was that incredible to you? That the mother and father of these two young men were prepared to go to such great lengths to see them risk their lives together?
Zink: It is kind of incredible. But it may be it's indicative that they really know their sons and maybe what their sons really desired.
Col. Zink and the brothers' company commander, Major Mark Wood, struggled for weeks to come up with a way they as commanders could go against convention and support sending the brothers into combat together.
Logan: You decided what?
Mark Wood: They would not be in the same squad - different squads - and they would not be on the same mission.
Logan: So those were the only restrictions?
Logan: Some would call that a brave decision, considering the risk.
Wood: It's my decision. I would have to live with it.
The Beans brothers had won, but the victory was not theirs alone. There were four other sets of brothers in the Lone Star Battalion and all of them would now be allowed to serve together.
Zink: I've never heard of five sets in one battalion. That's truly extraordinary.
Zink: Unprecedented, yes.
