The robbers, who arrived on three scooters, fled seconds after the red-coated pensioner, who does not wish to be named, began lashing out at them with a big black handbag.
The brave elderly lady said that when she first saw the gang she originally thought there was a fight going on and it was only when she got closer to them that she realised it was a robbery in the making.
She said she felt angry the gang thought they could get away with it and when one of the men on a scooter nearly ploughed into a woman and a baby in its buggy, she decided to leap into action.
'I clobbered him with my shopping but he got away,' she told the Northampton Chronicle.
'The rest of them were still trying to smash and grab at the jewellery.
'I didn't know what happened next but I just kept swinging my bag.'
She went on to describe how she 'landed several blows' on the back of one of the robbers and brought him to the ground as he tried to get away on his scooter.
