The Japanese army had high morals and empowered, if the would have fought a battle with sustancial resistance in Nanjing the chinse would have lost all.
Explanation:
In the first place, the Japanese Army had taken Shanghai which had a very big and substantial amount of resistance. A factor that empowered the Japanese forces, also by capturing it they controlled the resources and the flux of them. Limiting their distribution, the Japanese army controlled a very important strategic point. In the second place, Nanjing had enough Chinese forces to fight a good battle of resistance, however by being an industrial important city it represented a very big risk. If the Chinese lost their forces along with the economical power of Nanjing, they would have lost a very decisive fight that might have cost them the war or the opportunity of a comeback in another point. However, they decided to take a loss of the strategic point without performing a high scale defense, because they decided it was better to save the troops. The city reunited thousands of refugees in a safe zone with a temporary government under Japanese command and helped them survive by claiming their rights as refugees, they had many foreigners among them and they provided them a nice chance.
