Problem: Bartlett:  Gentlemen , no doubt you 've heard the immortal words of our new commandant : devote your energies to things other than escape , and sit out the war as comfortably as possible .
Sedgwick: Ha !
Bartlett: Well , that 's exactly what we 're going to do . We 're going to devote our energies to sports and gardening , all the cultural pursuits as far as they 're concerned . In fact , we 're going to put the goons to sleep . Meanwhile , we dig . Now , even a superficial look at the compound shows us that Huts 104 and 5 are closest to the woods . The first tunnel goes out from 105 , directly east under the vorlager , the cooler , and the wire .
Willie: But that 's over three hundred feet , Roger !
Bartlett: Did you make a survey , Dennis ?
Cavendish: Only a temporary one , sir . I make it just over three hundred and thirty - five feet .
Bartlett: Let me know when you 've got an exact _ one _ . Willie , this time we 'll dig straight down thirty feet before we go horizontal . That 'll rule out any question of sound detection or probing .
Willie: All right , Roger . But did you say " the first tunnel " ?
Bartlett: I did . There will be three . We 'll call them Tom , Dick , and Harry . Tom , as I said , goes out directly east from 104 . Dick goes north from the kitchen , and Harry goes out parallel to Tom from 105 . If the goons find one , we 'll move into the other .
MacDonald: How many men do you plan to take out , Roger ?
Bartlett: Two hundred and fifty .
Bartlett: There
Bartlett: will be no half - measures this time , gentlemen . There will be identification papers and documents for everyone . And Griff , we 'll need outfits for the lot .
Griffith: Two hundred and fifty ?
Bartlett: Mostly civilian clothes .
Griffith: Yes , but , um ... okay , Roger .
Bartlett: Mac . Maps , blankets , rations , compasses for all the walkers , and timetables for every train .
MacDonald: Right , Roger .
Colin: Sorry
Colin: I 'm late , Roger .
Bartlett: It 's all right , Colin . Sit down . We 're going to tunnel .
Colin: Splendid .
Bartlett: Willie , you and Danny will be tunnel kings . Danny , you 'll be in charge of traps , and I 'll work out the exact location with you tomorrow .
Danny: Good .
Bartlett: Sedgwick , manufacturer . Griffith , I said , tailor . Nimmo and Hayes , diversions . Mac , of course , will take care of intelligence . Hendley ? We haven't met . Scrounger ?
