They had around 2 squadrons of Mirage IIIs, with only a limited night/lookdown-shootdown capability, to cover the whole of Argentina. Take a look at a map. One or two Vulcans a night, or low level during the day, could have run riot. And once the raids started they knew we had the bombers and the capability. And a stick of 20 x 1000lbs is not to be lightly dismissed.
Low level over Buenos Aries, presidential palace, parliament, miltiary headquarters? Ports, airfields, the list of potential targets was endless. Even leaflet drops in a low level pass would have had a dramatic effect.
Regardless, the fact is the generals withdrew the IIIs to protect the capital, and themselves rather than their troops in the field. Their bravery knew no bounds....
