What happened during the rebellion against Richard III in southern England in 1483?

In late 1483, a significant rebellion against Richard III erupted in southern England, driven by members of the Yorkist establishment and county elites who joined forces with the Wydevilles and Henry Stafford, 2nd duke of Buckingham.1

The uprising was fueled by growing hostility toward Richard, exacerbated by rumors that he had murdered his nephews, the sons of Edward IV. Buckingham, initially a key supporter of Richard, turned against him and plotted to elevate the exiled Lancastrian Henry Tudor to the throne.123

The rebellion ultimately failed. Buckingham’s attempt to move troops into Herefordshire was thwarted by severe flooding, which caused his army to disintegrate; he was subsequently captured and executed. While Richard successfully suppressed the revolt, he was unable to capture most of the other leaders, who escaped to Brittany. There, they formally recognized Henry Tudor as their candidate for the kingship on Christmas Day 1483, setting the stage for the eventual conflict that would end Richard's reign.231
