midnight
As the six plodded along through the darkness there was no conversation . None of the Canadians spoke German , and Hal and Chester had instructed them to be silent , for the sound of a few English words would have done more to destroy the success of their venture than any other possible thing . As for Hal and Chester , both of whom spoke German fluently , neither felt like talk . It was almost midnight when the lads saw before them what appeared to be the lights of a small town . Approaching closer , they saw that they were , indeed , approaching a settlement of some kind . `` Cambrai , do you suppose ? '' asked Chester .
