Did Tecumseh accomplish his goal

Like all people he accomplished some of his goals, and failed at others.

One of his largest goals was to unite all Native Americans against the 'white man' and their invasion. Tecumseh realized that the 'white man' was a single unified force in that goal and would use any tool at their disposal to accomplish that goal. Without a unified resistance across all tribes, then the old rule of 'Divide and Conquer' would apply and the Native Americans would loose. History, of course, shows us that is what happened; and even today inter-tribal conflicts prevent tribes from asserting a unified front to enforce treaties.
