Springfield, Mo.,
The battle of Oak Hill has been fought, and we have gained a great victory over the enemy commanded by Gen. S. Lyon. The battle was fought ten miles from Springfield. The enemy were nine or ten thousand strong; our force was about the same. The battle lasted six and one-half hours. The enemy were repulsed and driven from the field with loss of six pieces of artillery, several hundred stands of small arms, eight hundred killed, one thousand wounded, and three hundred prisoners. General Lyon was killed, and many of their prominent officers. Our loss was two hundred and sixty-five killed, eight hundred wounded, and thirty missing. We have possession of Springfield, and the enemy are in full retreat towards Rolla.
