André spoke to General Clinton, who gave him broad authority to pursue Arnold's offer. André then drafted instructions to Stansbury and Arnold. This first letter opened a discussion on the types of assistance and intelligence Arnold might provide, and included instructions for how to communicate in the future. Letters would be passed through the women's circle that Peggy Arnold was a part of, but only Peggy would be aware that some letters contained instructions written in both code "and" invisible ink that were to be passed on to André, using Stansbury as the courier.
