How to run a windows batch script from Cygwin bash with a string parameter of the form "a=1"?

I have the following simple Windows batch script:

@echo off

echo Parameter 1: "%~1"
echo Parameter 2: "%~2"

When I execute it from the Windows command line (cmd) I get the following desired output:

C:\windows-script.bat "a=1" b
Parameter 1: "a=1"
Parameter 2: "b"

I now would like to execute the same script from a Cygwin bash command line and get the same output. Unfortunately I was not able to achieve what I want. Here are three unsuccessful trials:

$ /cygdrive/c/windows-script.bat "a=1" b
Parameter 1: "a"
Parameter 2: "1"

$ /cygdrive/c/windows-script.bat 'a=1' b
Parameter 1: "a"
Parameter 2: "1"

$ /cygdrive/c/windows-script.bat '"a=1"' b
Parameter 1: "\"a"
Parameter 2: "1\"""

Any ideas how to execute the batch script from Cygwin bash in the desired way?

This is one way of running it :

$ cmd <<< 'C:\windows-script.bat "a=1" b'

The syntax of <<< is equivalent to typing :

cmd

then typing :

C:\windows-script.bat "a=1" b

For more detail on <<<, see man bash
