Pensacola and its importance

My topic is on Pensacola, Florida and its importance during the colonial times. My primary source is "Kingdoms Face to Face: French Mobile and Spanish Pensacola, 1699 - 1719" by Robert Weddle. This source directly relates to my topic of Pensacola during the Spanish rule. This source is useful because it narrows down the date to 20 years and it talks about the importance of Pensacola during this time period, to the Spanish and other imperial powers like the British and the French.
