I feel that the Japanese colonel (Saito) was a leader who believed in commanding and making people work indifferently. His rules did not differentiate between the working style and respect given to an officer from a soldier. He was assigned to build a bridge within a deadline and his focus was to complete the bridge with the prisoners of war (British soldiers) who were led by a few officers and a colonel (Nicholson).
I am in awe of the never say die leadership style of the British Colonel Nicholson. He was a leader who wanted the best for his men and understood the strength and weakness of his soldiers. He was a proud egoistic leader who followed his military discipline and code despite of the torturous conditions he and his men were put through. The conflict arose when Saito asked all officers to work as manual laborers whereas under the British law officers did not have to do manual labor work. The British colonel denied to work despite of difficult conditions that Saito got him through .He was adamant that the officers would not work and finally got Siato to agree. This was also the time that was wasted making it difficult for the bridge to be completed on time.
Nicholson was a dominant leader and delegated his role to the best engineers with all trust. He wanted to show the Japanese that they were powerful and more superior in any form and this was where Nicholson went ahead and got his team and expert engineers to build a much superior bridge that the Japanese could not have built in many more years.
The leadership style he showed was incredible but he in the vigor to prove his supremacy over Saito lost the actual sight of the time
