On the following day, a detachment of the Boys under Seth Warner's command went to nearby Fort Crown Point and captured the small garrison there. On 14 May, following the arrival of 100 men recruited by Arnold's captains, and the arrival of a schooner and some bateaux that had been taken at Skenesboro, Arnold and 50 of his men sailed north to raid Fort St. John, on the Richelieu River downstream from the lake, where a small British warship was reported by the prisoners to be anchored. Arnold's raid was a success; he seized the sloop HMS "Royal George", supplies, and a number of bateaux.
