The town of Woodbury was overrun by walkers and abandoned by its residents.
After the Governor’s attack on the prison in the TV series “The Walking Dead,” the remaining survivors of Woodbury, including the elderly and children, were brought to the prison to live with Rick’s group. The town itself was left deserted and eventually overrun by walkers, as is the fate of many locations in the post-apocalyptic world of the series.
In more detail, Woodbury was initially introduced as a fortified town led by the Governor, where survivors of the zombie apocalypse had found refuge and a semblance of normal life. However, the Governor’s leadership was marked by brutality and a desire for control, which led to conflicts with other survivor groups, most notably Rick Grimes and his group.
The Governor’s obsession with defeating Rick led to a series of violent confrontations. After a failed assault on the prison, the Governor executed many of his own people who refused to continue fighting. He later regrouped with new followers and launched another attack on the prison, which resulted in a battle that left the prison in ruins and forced both groups to scatter.
The survivors from Woodbury who were taken in by Rick’s group integrated into the prison community until the prison’s fall. After that event, the fate of Woodbury was not explicitly revisited in the series, but it can be assumed that without its inhabitants and with the widespread chaos, it fell into disrepair and was overrun by the ever-present walkers, like many other settlements in the harsh world of “The Walking Dead.”
