I am interesting in the notion of cobordism.
 In particular, I want to understand Smale's proof of Poincare conjecture
 in higher dimention.
 In a webpage, I knew that the proof is followed by h-cobordism shortly.
 However, I do not notice that proof.


Please tell me how to proof it.
 I like simple proof diagramatic and know h-cobordism theorem.


Thank you for your considerations.



Generalized Poincare conjecture from h-cobordism
In order to prevent this question from resurfacing periodically due to the lack of an answer, here's a summary of the answers that are in the comments.


* Milnor's "Lectures on the h-cobordism theorem"
* Kosinski's "Differential Manifolds"
