The Battle of Thomas Creek, also known as the Thomas Creek Massacre, was an ambush of a small detachment of mounted Georgia Militia by a mixed force of British soldiers, Loyalist militia, and British-allied Indians on May 17, 1777 near the mouth of Thomas Creek in northern East Florida. The encounter was the only major engagement in the second of three failed attempts by American forces to invade East Florida in the early years of the American Revolutionary War. The invasion attempt consisted of a naval flotilla carrying Continental Army troops and a company of militia cavalry traveling overland. The flotilla was delayed in reaching the rendezvous point, and British intelligence had learned of the expedition and located the cavalry. The British established an ambush, which broke up and scattered the cavalry, taking more than 30 prisoners. The Muscogee were reported to kill a number of the captives in cold blood afterward, in revenge for the death of a member of their own tribe in an earlier skirmish. Colonel Samuel Elbert, the invasion commander, abandoned the expedition when his flotilla was confronted by narrow channels and prepared British defenses. A 1778 expedition against East Florida failed due to leadership disagreements, although there was a skirmish at Alligator Bridge

The Montgomery Correctional Center, previously known as the City Prison Farm and Montgomery Correctional Center, started in 1958, on a large, 640-acre (2.6 km2) tract in the northwestern part of Jacksonville, Florida. In 1958, two large buildings were constructed for the prisoners, and a third building was constructed to accommodate facilities for canning many of the agricultural products to be raised on the broad and fertile land that surrounded the prison. The prisoners farmed the land and grew their own vegetables, and raised pigs and cattle for meat and milk to be used in the Prison Farm operations. By 1961, the inmate population consisted of misdemeanor offenders, which averaged approximately 200 males and 50 females. By the end of 1962, the City Prison Farm was a self-supporting facility, where they performed tasks such as agriculture, canning, freezing, meat curing, laundry and sewing. With the consolidation of the city of Jacksonville in 1968, the City Prison Farm was renamed as the Jacksonville Correctional Institution. As Jacksonville was becoming the largest city in the United States, in terms of land area, it encompassed the prison unit. In dedication to Director James I. Montgomery, in 1986, the Jacksonville Correctional Institution was renamed the Montgomery Correctional Center. With the ever-growing inmate population of Jacksonville, Florida, the prison had to expand its facilities. In 1976, the "B" Wing was constructed to add to the men's unit. In 1985, the "D" Wing was added to the women's division which was known as the "C" Wing. The North Unit was constructed in 1989, to replace the original "A" and "B" wings. In 1994, the original "A" and "B" wings were closed down. During 1999, the "B" Wing was renovated to become the new housing unit for the female population, and the original "C" Wing was demolished. Of the C/D wings, the remaining "D" Wing was renovated in 2002, and became the male annex, supporting the North Unit in housing male inmates since 1994. Located on the north side of Jacksonville, Florida, Montgomery Correctional Center currently consists of two compounds: the North Unit is designed for the sentenced and unsentenced male inmates, with a capacity of 552 prisoners; the South Unit ("B" Wing) is for sentenced male inmates, with a capacity of 160 prisoners. In addition, an Annex ("C" Wing) houses an additional 64 prisoners, with a total population of 776 for the center. The Montgomery Correctional Center provides care, custody and control of the sentenced prisoners, while utilizing prisoner labor which has supported the general good of the citizenry of the city by providing selected work programs throughout the city. On a daily basis, nearly two hundred men and women prisoners work on the supervised prisoner work crews which work in many troublesome areas such as: where illegal dumping occurs; deteriorating neighborhoods and in special areas where citizens have requested assistance. The Federal, state and local government agencies have also utilized the prisoner work crews throughout Duval County, Florida, to help defray their operating costs. Prisoners who are not able to work on the work crews are required to either participate in treatment or educational programs, unless they are certified sick by a member of the medical staff.

The Machaba Balu Preserve is a nature preserve encompassing 10,000 acres (4,000 ha) of protected lands in northeastern Florida, just to the northeast of Jacksonville, at the confluence of the Nassau, the St. Marys, and the St. Johns Rivers as they flow toward the Atlantic Ocean through a wide network of islands, canals, and tidal marshes. The name Machaba Balu means "saved marsh" in the language of the Timucua people, who occupied the area in pre-Columbian times and met the first European explorers of the region; the Timucua never used this name themselves, however, as it is a modern language construct. The preserve, created with land purchased in 2002 mostly from Alcoma Corporation by the Nature Conservancy, includes 77 islands and numerous individual tracts of tidal marshland between the Nassau and the St. Johns Rivers. The largest clusters lie to the west of Little Talbot Island State Park and on either side of Sisters Creek south of the large fork.The Nature Conservancy chose to preserve these lands as a region of significant biodiversity that supports an important fish hatchery and spawning area for commercial and recreational fishing in Florida; its estuaries and tidal creeks provide habitat for manatees, dolphins, sea turtles and terrapins; numerous species of shorebirds and wading birds feed and nest there as well, some listed as threatened or as species of special concern. Hammocks of higher ground rise above the floodplain, with forests inhabited by rare species of plants and animals, including the Florida black bear and the red-cockaded woodpecker; bald eagles and ospreys are found in their stands of hardwood trees, and painted buntings in the underbrush. The entire ecosystem is vulnerable to pollution caused by surrounding coastal development.
