Last time fornost was destroyed Gondor didn't come until theywere too late, and that was with a one year notice. How long do you think it will take for Gondor to come to the rescue when Arnor doesn't see it coming? By the Time they get there Fornost will already be controlled.

Lets think about it,

The wights already live in Eriador

Sorthog could make it down within a week then he would decend into the barrows where it will seem like the orcs are just plundering the wights supplies

Umbar could sail up to the little strip of beach that is part of Eriador in about a months time and also decend into the barrows

Once all three factions are in the barrows they will take the tunnels to just next to Fornost and flood the city

At this point messengers will ride to Gondor which would take about a week on account of the mountains

Because of the mountains it would take another three weeks to a month for reinforcements to arive in Eriador at which point Fornost will already have been taken and heavily fortified

The undead would have significantly grown after the siege so I'm pretty sure Umbar Sorthog and the newley bolstered undead could hold the city

But just because I'm telling you the plan doesn't mean that your characters instantly get to know, they wouldn't realize that Arnor is the target until the siege already started because the 3 facs would take the underground tunnels
