Accounting for the escapees
POSSIBLE SPOILERS
The morning after the escape the Germans run a check and find that 76 POWs have broken out. All right. Here's what we later learn about the prisoners' fates:
(a) 50 of the POWs were shot by the Germans. At first this seems to be limited to the men killed in the mass murder of prisoners near the end of the film. But apparently it also includes Ashley-Pitt (David McCallum), who had been shot earlier at the railroad station (when he was attempting to flee after killing the Gestapo agent who had recognized Bartlett). When Ramsey (James Donald) reads the list of the 50 to the remaining prisoners Ashley-Pitt's name is on it. So the 50 apparently consists of Ashely-Pitt plus 49 men gunned down in cold blood in the hills.
(b) 1 man, Blythe (Donald Pleasance), was also shot by the Germans, after he and Hendley (James Garner) crash-land their plane. But his name isn't included on the list of the 50; Ramsey doesn't mention it when he reads the list out, and he only finds out about Blythe when Hendley and his small group are returned and Hendley tells him what happened. It's a little odd that Ashley-Pitt's name is on the list but not Blythe's, since both men were shot apart from the main massacre, but anyway, with Blythe the total number of men shot is 51.
(c) 11 men are captured and sent back. This is the group that includes Hendley, but it's hard to tell if it also includes Hilts (Steve McQueen). Because of the camera angles and the way some of the men are standing in back of others it's difficult to get an exact count of how many came in with Hendley, but it does appear to be just 10, meaning Hilts, who arrives a little later, is the 11th.
(d) 3 men actually get away: Danny and Willy (Charles Bronson and John Leyton) row their stolen rowboat down to a harbor and board a Swedish ship, and Sedgwick (James Coburn) escapes into Spain.
Okay, summing up these men's fates: 51 are gunned down; 11 captured and returned; 3 succeed in getting away. That's 65 men.
So, my question is: if 76 escaped, what happened to the other 11?
True, Ramsey does tell Hendley and his group that "you're the first" returned to the camp, which implies that the other 11 have been captured and will eventually be sent back, but we never hear anything about them, which is strange.
Also, the film is dedicated to "the fifty" but since that doesn't include Blythe, shouldn't it have also honored him and been dedicated to "the fifty-one"?
