"dos" (i.e. cmd.exe) does not have the same quoting rules as bash,
so \\ inside single quotes means the same as it does inside double
quotes in bash.
Why are you even trying to use backslashes? There's no need (even
in cmd.exe), but there's certainly no point in using them in a posix
command. Just replace all backslashes with forward slashes and you've
sidestepped the problem.
If you absolutely MUST have backslashes, from cmd.exe, you need to
double each backslash:
H:\>C:\cygwin\bin\bash -v -c '\\\\UNC_PATH\\Dir'
(actually only the first really needs to be doubled, because \ has
no special meaning if it's followed by a letter)
