Where did Bf-109 and LaGG-3 get hydraulic power?

In BoS you can operate the landing gears and LaGG flaps even when the engine is not running. Is this really possible or is it just a BoS thing? Where did these planes get their hydraulic power if not directly from the main engine?

Not a 100% sure but  the Spitfire had a hand operated hydraulic pump in the cockpit for use in emergencies. Looking at a RAF training film the other day when the ground crew were using the pump when checking out the undercarriage light operation.  So I assume other planes would have similar.
