On 3 August 1780, Arnold obtained command of West Point. On 15 August he received a coded letter from André with Clinton's final offer: £20,000, and no indemnification for his losses. Due to difficulties in getting the messages across the lines, neither side knew for some days that the other was in agreement to that offer. Arnold's letters continued to detail Washington's troop movements and provide information about French reinforcements that were being organized. On 25 August Peggy finally delivered to him Clinton's agreement to the terms.
