Carlisle United needed to gain three points from the final game of the season at home to Plymouth Argyle to retain their League survival or be relegated from the Football League for the first time since 1928. Scarborough (Carlisle's relegation rival) merely needed to draw against Peterborough. News had already flashed through to Brunton Park that Scarborough had achieved all they needed to do, drawing against high flying Peterborough at the McAlpine Stadium 1-1 each. The score line remained 1-1 at Brunton Park on 90 minutes and the crowd at Scarborough were already celebrating before the fourth official stated four minutes of extra time would be played at Brunton Park. In the 95th minute of stoppage, goalkeeper Jimmy Glass, who had signed in an emergency loan deal from Swindon Town after the transfer deadline, sprinted from his goal line, arrived late in the box for a corner kick, Scott Dobie’s flashing header was parried by the Plymouth goalkeeper straight to the feet of Glass, who with the last kick in the game wasted no time in smashing the ball home in one of the most dramatic ends to a Season ever witnessed.
Revenge would be gained a month later when United went to the Roses ground at Maryport Cottages and beat them 2-1 in another nip and tuck match. It was in this 1904/05 season that Carlisle United entered the FA Cup for the first time. They were drawn to play against Workington who were, at that time, the top side in Cumbria. In fact, so good were thay that they comfortably held their own in the Lancashire Combination League. The Cup game ended in a 2-2 draw with the West Cumbrians running out as 3-1 winners in the replay.
By that time Red Rose had won the Cumberland Cup Final, beating Frizington White Star who had just pipped them for the Cumberland League title. On 30 April 1906 United and Red Rose met in a friendly match in aid of the Red Rose club. The result was a 1-1 draw.  After the league reorganised four years later the board at United decided it did not suit the club's best interests to be there any longer and the club entered the North Eastern League in place of their reserve team who had previously played in the league and been a founding member. When the Carlisle United first team left to join the Football League the reserve team resumed its place in the competition.
 The crest itself may have been derived from Sir William de Carlyell of Cumberland, in the reign of Edward II, who bore a red cross. The supporting red wyverns to either side of the shield are a symbol of the British Kingdom of Cumbria. The motto on the underlying scroll reads: ‘Be just and fear not’, which is a quote from Shakespeare's 'Henry VIII'.  Carlisle were often referred to as 'The Foxes' due to the local connection with huntsman John Peel.
