Try "exit"ing from the bash process... :-)  When you start an interactive
bash process, it doesn't return until you leave it.  You can verify that
you're in a different bash process by changing the prompt via "PS1='$ '"
and then observing that the new bash sets the prompt to the default value.

FWIW, the following works:

batch2.bat contains:

@echo off
echo %1
bash -c "echo $BASH_VERSION"
echo %1
exit

The result:

$ ./batch2.bat test
test
2.05b.0(1)-release
test

The batch file called from a batch file is a red herring, as others
mentioned.
