Season 1920-21

The ground is returned by the War Office. After repairs to the pitch and stands are complete a friendly against Old Bancroftians becomes the first home game for six years. Town enter the Amateur Cup, losing in the 2nd qualifying round, make the 3rd round of AFA Cup before losing to Ealing, and finish a creditable third in the Southern Amateur League. Chelsea are beaten 1-0 in an end of season friendly watched by a full house of over 8,000 at Portman Road.

Season 1921-22

Town win the Southern Amateur League with an impressive record of 13 wins, 6 draws and just a single defeat. The title is clinched on the last day of the season with a 2-1 win at Eastbourne who finish a point behind Town in second place. An impromptu procession of the town takes place when a crowd of around 4,000 meets the team at Ipswich station later that night. Chelsea again visit Portman Road but this time run out 7-1 winners. A good run in the Amateur Cup is also enjoyed, Town reaching the second round proper.

Season 1922-23

Eastbourne take the Southern Amateur League title, with Town finishing runners-up just a point behind. Town had beaten Eastbourne at Portman Road on the opening day of the season but oddly the rematch at Eastbourne was never played and in early May the SAL declared the south coast side champions!

Season 1923-24

An indifferent season - considering the two that had preceded it - with early exits from both the AFA and Amateur Cup’s and a mid-table finish in the Southern Amateur League.

Season 1924-25

Town, still in contention for the SAL title with just two games remaining, lose both and finish fifth, four points behind champions Midland Bank. Kirkley beat the Blue’s 1-0 in the Suffolk Senior Cup Semi-Final, while in the AFA Cup the 3rd round is reached before defeat by Merton.

Season 1925-26

Town prop-up the Southern Amateur League during the early part of the season before a final finish of 4th bottom. A 2-1 defeat to Chelmsford in the 2nd round of the East Anglian Cup marks Town’s debut in this new competition, while in the AFA Cup Round 3 is reached.

Season 1926-27

A roller-coaster season with some bizarre results including a 10-5 loss away to Ealing and a 9-0 victory recorded by Town in the return game at Portman Road. Off the field Flight-Lieutenant SN Webster, who played for Town between 1925 and 193,0 broke the world air speed record in Italy to win the Schneider Trophy with an average speed of 281,656 mph.

Season 1927-28

Edwin Dutton becomes the club's first professional trainer. The 37 year-old, who at one time had been on Newcastle United's books, won a cap for the German national side despite being born in South Shields. Town reach the AFA Cup Final for the first and last time, and having beaten fellow finalists Bank of England 4-1 in the league a few weeks earlier are favourites to win the trophy. However, the final at Dulwich Hamlet ends in a 4-2 defeat despite the support of over 2,300 fans who have travelled down from Suffolk for the game. The Blue's win the Suffolk Senior Cup final with a 2-0 final victory against HMS Ganges as a consolation.

Season 1928-29

Town make their first ever appearance at Wembley Stadium. Opponents Ealing were given permission to use the national stadium to host their home league games while their own ground was waterlogged. 1,200 witness a 4-0 win by the Blue's. The Suffolk Senior Cup is retained with a 5-0 trashing of Woodbridge Town.

Season 1929-30

Town sweep the board, winning the Southern Amateur League, the Suffolk Senior Cup and the Ipswich Hospital Cup. The season starts with a home loss but 15 successive wins follow as the league title is won with a six-point cushion.
