After finishing as runners-up in the ICC Champions Trophy, England faced Australia in back-to-back Ashes series. A 3–0 home win secured England the urn for the fourth time in five series. However, in the return series, they found themselves utterly demolished in a 5–0 defeat, their second Ashes whitewash in under a decade. Their misery was compounded by batsman Jonathan Trott leaving the tour early due to a stress-related illness and the mid-series retirement of spinner Graeme Swann. Following the tour, head coach Flower resigned his post while Pietersen was dropped indefinitely from the England team. Flower was replaced by his predecessor, Moores, but he was sacked for a second time after a string of disappointing results including failing to advance from the group stage at the 2015 World Cup. He was replaced by Australian Trevor Bayliss who oversaw an upturn of form in the ODI side, including series victories against New Zealand and Pakistan. In the Test arena, England reclaimed the Ashes 3–2 in the summer of 2015.
England's first match after the war was in the 1920–21 season against Australia. Still feeling the effects of the war England went down to a series of crushing defeats and suffered their first whitewash losing the series 5–0. Six Australians scored hundreds while Mailey spun out 36 English batsmen. Things were no better in the next few Ashes series losing the 1921 Ashes series 3–0 and the 1924–25 Ashes 4–1. England's fortunes were to change in 1926 as they regained the Ashes and were a formidable team during this period dispatching Australia 4–1 in the 1928–29 Ashes tour.
