Now comes parts 2 and 3 - at home to Rotherham next Saturday and then a trip to Dagenham on the final day of the season.
After Saturday's results, the Stags are now just one point off safety and avoding relegation from the Football League for the first time.
Manager Paul Holland labelled the victory as part one of a trilogy and hero striker Boulding praised the supporters for their part in the vital victory.
Stags fans created a 'BELIEVE' banner for the recent local derby at Notts County and it was at Field Mill again on Saturday.
The club has created the Great Escape poster, and even draped one on the Andrew Saunders Insurance Stand.
The Great Escape theme tune was played after the three goals on Saturday.
Almost 3,000 home fans also backed the Stags against Shrewsbury, some taking advantage of a discounted ticket offer.
But what do you think? Is the Great Escape still on? Do you Believe the Stags will be playing Division II football next season? Or will it be the Conference after 77 proud years in the Football League? Let us know below . . .
