Now, if the question is, "Why deceive your own troops about leaving, rather than jsut the enemy," I start to run out of answers. Perhaps Stanley has become convinced that Parson, Wanda, or Sizemore really has betrayed him, and he thinks that person is in communication with Ansom?

It's a WAG, though....
No. While he he admits that as a possibility, his mind is set on following what he believes to be the will of the Titans. The Titans have told him that he must act alone, and so Wanda, Sizemore and Parson will not fit into his plans. If he truly believed that they had betrayed him then he would have simply disbanded them, or worse.
