Task: Question Generation
Input (English): Passage: The greatest single victory of the SNA-WSLF was a second assault on Jijiga in mid-September , in which the demoralized Ethiopian troops withdrew from the town. The local defenders were no match for the assaulting Somalis and the Ethiopian military was forced to withdraw past the strategic strongpoint of the Marda Pass, halfway between Jijiga and Harar. By September Ethiopia was forced to admit that it controlled only about 10% of the Ogaden and that the Ethiopian defenders had been pushed back into the non-Somali areas of Harerge, Bale, and Sidamo. However, the Somalis were unable to press their advantage because of the high attrition on its tank battalions, constant Ethiopian air attacks on their supply lines, and the onset of the rainy season which made the dirt roads unusable. During that time, the Ethiopian government managed to raise and train a giant militia force 100,000 strong and integrated it into the regular fighting force. Also, since the Ethiopian army was a client of U.S weapons, hasty acclimatization to the new Warsaw Pact bloc weaponry took place. From October 1977 until January 1978, the SNA-WSLF forces attempted to capture Harar during the Battle of Harar, where 40,000 Ethiopians had regrouped and re-armed with Soviet-supplied artillery and armor; backed by 1500 Soviet "advisors" and 11,000 Cuban soldiers, they engaged the attackers in vicious fighting. Though the Somali forces reached the city outskirts by November, they were too exhausted to take the city and eventually had to withdraw to await the Ethiopian counterattack.
Output (English): The Battle of Harar took place in what interval?
