Looks the Battle for Mosul had ended as of Sunday. A timeline is here: https://www.yahoo.com/news/iraq-battle-mosul-135450223.html
This thing took forever. The offensive started on 17 October. They entered the city on 1 November. It then took 251 days to take the city (over 8 months). This is one of the interesting challenges of urban warfare, it takes 15 days to get to the city and 251 days to take it. As we noted in our three urban warfare studies (and in two chapters in War by Numbers), operations outside of the urban area go so much faster than in the urban areas. The end result is that most urban warfare eventually turns into a giant mop-up operation.
I notice there has been a renewed interest in urban warfare, especially with discussions of fighting in mega-cities. I am not sure that everyone involved in these efforts grasp that these fights are not occurring at the point of the spearhead, but are indeed often a mop-up operation, regardless of the size of the city.
Mosul is in ruins. It is certainly one of the largest cities that ever had an extended urban fight in it. It is larger than Stalingrad.
So…does anyone have some good casualty figures for this fight?
