About Dorsey[]
After a long session in OR, the doctors are met by a Major Weems (Tom Atkins), who is here to see his men, of which Dorsey is one of. Everyone is impressed that Weems made a trip this late at night, but he says its the least he could do.
In Post-Op, Weems suggests that Dorsey, who, at first, impressed the surgeons over his seeming concern for his soldiers and guilt when they offered him to sleep with them in a bunk in the swamp instead of the visiting Officers' Quarters - should be sent home, but Hawkeye tells him the young man's wounds aren't that serious. Weems, who is insistent, tells Hawkeye privately that Dorsey comes from a poor farm family, and they really need him back home. Hawkeye promises to see what he can do.
Later, when Father Mulcahy happens to mention that Dorsey is from Brooklyn (raised on Bainbridge Street in the Bedford-Stuyvesant neighborhood), which doesn't jibe with what Weems told Hawkeye. Hawkeye then asks Dorsey (Lawrence Fishburne) about living in Brooklyn, and his story checks out.
He asks Dorsey about about Weems, which elicits a surly, tight-lipped response.
After talking it over with B.J., Hawkeye and he both notice that Weems is desperate to send Dorsey - a black man - home, but wants to keep the more seriously wounded Sturdevant, who is white.
That doesn't seem to make sense to either of them; it doesn't exactly give a good impression to them, as they later discovers his true motives in seeing Dorsey and other black soldiers in his unit discharged: just to get them out of his unit.
