Langsdorff was ordered to avoid combat, even with inferior opponents, and to frequently change position.[13] On 1 September, the cruiser rendezvoused with her supply ship Altmark southwest of the Canary Islands. While replenishing his fuel supplies, Langsdorff ordered superfluous equipment transferred to the Altmark; this included several of the ship's boats, flammable paint, and two of her ten 2 cm anti-aircraft guns, which were installed on the tanker.[14]
