Field Marshal William J. Slim said:
There is only one principle of war and that's this. Hit the other fellow, as quickly as you can, as hard as you can, where it hurts him most, when he ain't lookin'.
Island Hopping, Part LXXV
Operation Chartreuse Shark, Part I
To instantly change the shape of the campaign in China, three airdrops are ordered that will effectively extend the northern front to completely squeeze the Japanese.
The first landing is at Yucheng
Which the Japanese quickly try to counter
Apparently the battle for Tianjin was instantaneous
Shijiazuang is secured without a fight, but the battle for Tianjin begins...again?
And it's over, again.
And the defenders of Yucheng hold!
With the taking of Tianjin we also isolate Tangshan!
Attacking from two sides, Tangshan is quickly reduced.
And destroyed.
