Stewart spoke to the clubs official site ahead of the crunch clash as the Millers look to build on a 1-0 first leg lead and book a place at Wembley.
The Chairman also touched on his pride to be representing the club and about the events over the weekend.
Tony said: "At the game on Saturday I thought we were magnificent, and when I say 'we' I mean players and supporters alike. I am so proud to be representing Rotherham United Football Club and I take that pride with me everywhere I go," admitted Mr.Stewart.
"Wednesday night provides us all with an opportunity that this Club and this Town hasn't had for a long time. We are under no illusion that there is a long way to go and that we are just at half time with our noses slightly in front at this stage.
"It was interesting to read in the Aldershot Matchday Programme, a piece that said Don Valley Stadium is 'hardly the most intimidating of venues', I think that sets down a challenge to us all."
Tony continued: "I don't think we have had a fair representation of what is happening at Rotherham United in national media recently and if this creates a siege mentality amongst us and unites everyone involved with this Football Club, either directly or indirectly, then that will only make us stronger.
"There are still a lot of Rotherham United supporters that haven't been to Don Valley Stadium for a whole host of reasons - this is a direct plea to each and every one of them - come on Wednesday night, get behind your team as the prize is for this Club to represent our Town on a national stage," he
added.
"I live in Rotherham, my business is in Rotherham and most of my employees are from Rotherham, that makes me very proud. I am extremely passionate and relentlessly dedicated to working with others to make a difference for Rotherham United Football Club and all I can ask is that, on Wednesday night, wear the red and white colours with pride, this is a great opportunity to show everyone what we're all about. Up The Millers!"
