As I said earlier the quotes are interpreted by the shell executing the
command. So the shell execing the cygstart command is not passing the
quote to the secondary bash session because it has interpreted them. If
you want to pass quotes to the process on the command line then you need
to quote them or use a backslash on the quote to prevent the shell doing
the exec to process them.
$ cygstart bash -c \'echo 1\; read\'
