In North Africa... The 8th Army occupies Tripoli. The repairs to the port facilities begin immediately and are completed by the end of the month.
In the Solomon Islands... On Guadalcanal, American forces begin to make rapid gains because of the Japanese withdrawal toward the Cape Esperance positions. The Americans fail to realize the significance. The Gifu strongpoint falls.
