Lachoneus does not accept the conditions. Perhaps he is surprised at the boldness because the previous battles between the Gadiantons and the Nephites have not been decisive. Each side has had their victories, so Lachoneous has no reason to expect that they should be overwhelmed this time. He decides not to accede. Of course this will mean that the attack is sure to come, so they must prepare. Part of his preparation is to have the people turn to their God for protection.
