Aldershot went out of business in March 1992. Their last home game was a 3-0 defeat by City but their last game of all was a 2-0 defeat at Cardiff.
Now, taking a deep breath:
In the 1990/91 season there were 24 teams in the Fourth Division but as part of a planned expansion of the league to 94 clubs 5 teams were promoted at the end of that season, only 3 relegated from the Third Division and no team relegated to the Conference. One team was promoted from the Conference.
So 23 teams started the 1991/92 season. Aldershot went out of business during it. At the end of the season Colchester were promoted from the Conference.
So 23 teams were due to start the 1992/93 season, but as stated Maidstone went out of business before playing any games, leaving 22 teams. At the end of the season Halifax went down and were replaced by Wycombe.
1993/94 - 22 teams
1994/95 - 22 teams.
The knock-on effect of the reduction of the number of teams in the Premier League after the end of the 1994/95 season meant 5 teams were relegated from the former Division Three and only 3 teams promoted from the former Division Four.
This left 24 teams for the 1995/96 season.
Questions may be asked on this later.
