Léry decided that Fort Williams was too strong to take with its garrison alerted. After destroying Fort Bull, the French headed north, arriving at Niaouré Harbor (modern Sackets Harbor, New York) on 3 April, when there were 9 bateaux full of supplies, which Léry had to send back to Montreal as he already had more than enough supplies with all of the barrels he captured at Fort Bull. On 10 April, Léry arrived in Montreal to write a report on the successful operation for the Governor-General.
