Sorin gets a hard think about it, "We can block it but the river can be also used as a water supply meaning we need to cut every inch of water that flows to Caer Peryln or where they can access it so easily" Having a lake as a water supply and cutting off was a good idea but if poisoning the river was decided it was simply out of option because it could impacted the townsfolk and villagers that has the same access to the river itself.<br/><br/>The problem is how she and the others can stage a siege to the castle for this situation. Water is the natural defenses and boat is simply out of option for this case. Some major problems is how strong the current is, how many depths the water will be and how many soldiers that can swim with their armor on them.<br/><br/>"Siege can be an option, we can cut off the food supplies for that. No one likes to drink a whole day without eating any food as the food is the sources of energy itself." Lack of food mean lack of energy and every possible got a problem itself. She sighs while try to think the best option to seize Caer Peryln with less casualty. One of the best option is to seize the floodgates and protects it until Caer Peryln was captured.<br/><br/>In the meantime, she assign Hyarmenion to defend Southern Rausten from any possible retaliation while she will lead Princess Ari and Rubii to Caer Peryln in order to capture Caer Peryln Castle.
