The long awaited battle that they waited and trained for an entire year for suddenly wasn't going to happen. When they arrived, the enemy claimed they wished to surrender. For many of them it didn't make sense, but as Bliss checked what the date was, she realised that they had arrived a day earlier than the set date.
This only confirmed her suspicions and the reason for the attacks beforehand, they had arrived before whatever the Shadow wanted to do could be done. If they were to fight now, then they would win this war with the help of Van and his crystal.
"Did they state the reason why?" Sir K asked.
"Apparently Gary is waiting on orders from the Shadow inside." Jack replied. "He himself no longer wishes to fight, but because of Gary's position they will not take a direct order from him to surrender so he is waiting for a reply from the Shadow and those above him."
