The Union lost the Battle of Fredericksburg because Burnside was unable to adapt to changing circumstances.

Explanation:

The Battle of Fredericksburg, which took place in and around Fredericksburg, Virginia, from December 11 to 15, 1862, between the Northern Virginia Army of Confederate General Robert E. Lee and the Army of the Potomac commanded by the Major General Ambrose E. Burnside, is remembered as one of the most unequal battles of the American Civil War. The Union Army suffered terrible losses in useless frontal assaults on December 13 against the well entrenched and barricaded Confederate defenders in the hills behind the city, bringing an early end and serious defeat for the army of the Potomac and for the Unionist campaign against Richmond, the capital of the Confederation.

it was certainly a debatable decision, mainly because it was based primarily on political - and not on legal or social - views. since the congress at that time was led by members of the republican party, and the territory that the tribes wanted to turn into an exclusively indian state was predominantly democratic, the proposal (as expressed in the constitution) did not succeed, but the constitution itself proved to be of crucial importance in the creation of the state of oklahoma, and, most importantly, it guaranteed the involvement of representatives of the indian tribes in the government of the future joint state.  

as a member of congress, i would have voted to ratify the constitution, or at least to have it tabled. ignoring it was an interested and partial decision.
