The enslaved people who took part in the Stono Rebellion of 1739 had the ultimate goal of reaching St. Augustine, Florida. Why was Florida their intended destination?

This is what i would put Augustine, Florida. Why was Florida their intended destination? Led by a slave named "Jemmy," the almost 80 slaves who participated in the Stono Rebellion of 1739 had the ultimate goal of reaching Florida because Spanish leaders had offered freedom to any slaves who managed to escape from the British colonies i hope this helped
