Well, they are finally going to re-take Mosul. I think we heard that before, but this time it is probably true.
Link: Mosul
They are saying they may take it by the end of 2016 or early 2017. That is a very long time, considering how close the Iraq Army is to it. They are 70 km (45 miles) away from Mosul! Mosul was taken by ISIL in early June 2014. So they are looking at 2Â 1/2 years before the second city of Iraq is reclaimed.
Just for comparison on 30 March 1972, the North Vietnamese Army and the Viet Cong started their large spring offensive (the Easter Offensive). On 1 May 1972, the South Vietnamese Army gave up Quang Tri in the most northern province in Vietnam. This was the provincial capital of Quang Tri province. They withdrew from the capital and the province at that time. In mid-September 1972, the South Vietnamese Army had retaken Quang Tri. This was 4 1/2 months later. They held it until the 1975 offensive, which ended South Vietnam.
