In the following days, everything went on as if before the reinforcement army arrived. Therribus sent small detachments just to keep Prince Alonzo's force inside the fort on their toes. Arther maintained his position close to the fort, taking action whenever Duchess Isabelle did. The two deterrents stood their ground.
Therribus sent a larger attack on the fort the third day after the reinforcement army arrived. His intention was as before, to keep the force inside the fort tense. However, the reinforcement army also attacked at that time. This forced Therribus to pull back his attack on the fort. In response, the reinforcement army also retreated.
As a result, Therribus abandoned the skirmishes altogether. With the reinforcement army on standby, he knew he couldn't apply enough pressure on the force inside Fort Garadhor. Might as well just save their strength and continued to wait.
