I think you did exactly correct connecting the jumper cables to the battery-the dead battery acts as a resistor and helps protect the starter etc. I agree-get the 12 volts off the system as fast as possible. Charging systems run at a higher voltage than the battery voltage. I have measured 8v with the engine running on my 47 Packard.
