The Empire has never sent any further reinforcements to the place or even tried evacutating the forces stuck there, so it can be assumed they've been given up for dead, especially with Regula's death, the Empire probably considers his legion extinct and not worth bothering with anymore.
So they're just remnant forces there, just like the remains of Gaius's XIVth still holed up in their assorted Castri within Eorzea, strong enough to resist any attempts by the Alliance to clear them out, but not strong enough to do anything else but defend their walls accordingly. And the Alliance has more pressing matters with pushing back Garlean forces on the border with Islabard to worry about a bunch of remnant Garlean forces holed up in Eorzea who are now little more than bandits in Garlean uniforms.
