Excerpts from Books and Wikipedia
"From the time he arrived in Tennessee Jackson absorbed powerful sentiments against all barriers to westward expansion and economic prosperity--be they Indian, Spanish, British, or whatever. Eventually he annihilated those barriers. More than any other man, Jackson was responsible for the removal of the Indians to the remote reaches west of the Mississippi River. More than any other man, he kept the British from returning to the Gulf Coast. More than any other man, he expelled the Spanish from their southern stronghold and made possible the transformation of the United States into a continental power." [Andrew Jackson I, p. 50] "He was a man of the highest integrity; his decisions were swift and devoid of hesitation. Moreover, he had a fierce sense of justice, however wrong-headed it might be at times. It was this sense that sustained his impartiality under most circumstances." [Andrew Jackson I, p. 113-4] "He could kill Indians with the best of them and burn their houses--but not when they were allies, not when they had proved their loyalty by feeding his troops and fighting alongside him. Loyalty was sacred to Jackson. . . . " [Andrew Jackson 1, p. 360-1]
