Fort De Soto Park


South-southwest of St. Petersburg, Florida, Fort De Soto Park is a park operated by Pinellas County on five offshore keys, or islands: Madelaine Key, St. Jean Key, St. Christopher Key, Bonne Fortune Key and the main island, Mullet Key. The keys are connected by either bridge or causeway. The island group is accessible by toll road from the mainland. Historically, the islands were used for military fortifications; remnants and a museum exhibit this history. Two piers, beaches, picnic area, hiking trails, bicycling trails, kayak trail, and a ferry to Egmont Key State Park are available.
The park is a gateway site for the Great Florida Birding Trail.

History

Early history

The land that would later become Fort De Soto was inhabited by the Tocobaga Native Americans from about 1000 to 1500 A.D. They lived on Mullet Key and other barrier islands in the area, thanks to the plentiful fish, clams, conch, oysters and whelks from the Gulf of Mexico, supplemented by occasional game food as well as the wild plants they gathered.
In 1529, the Spanish explorer Pánfilo de Narváez investigated the barrier islands after his expedition landed somewhere between St. Pete Beach and Clearwater. Ten years later, Hernando De Soto came ashore somewhere near the southern part of Tampa Bay, beginning what would culminate in the conquest of Florida for the Spanish Empire.

Military use

In 1849, a detachment of US Army engineers, including Robert E. Lee, who would later become the commander of the Confederate army, surveyed the area. They recommended Mullet and Egmont Keys become fortified as appropriate site for coastal defense installations. Both keys could only be reached by boat since they were islands off the mainland. Although no fortifications had yet been built, Union troops were stationed on the two keys during the Civil War to aid in the Union blockade of Tampa Bay, with the Egmont Key lighthouse acting as an observation tower. The keys were again abandoned by the military until 1882 when military reservations were officially created on the two keys. However, it would be several years before actual permanent construction would commence as a result of defense considerations linked to the Spanish–American War.
of Watervliet, New York, had a maximum range of at a 70° elevation and at 45°. It took a crew of 12 men to operate them.
Hillsborough County established a quarantine station on the eastern side of Mullet Key in 1889. It became known as Mullet Key Quarantine Station. The Marine Hospital Service took over jurisdiction of the station in 1901. The duty of the station was to inspect aliens aboard ships arriving from foreign ports. By 1925 the station operated with fifteen buildings. The quarantine station operated until 1937, when the Public Health Service transferred its operations there to Gadsden Point, near Tampa.
The main operation on Mullet Key, however, became Fort De Soto in 1900, named for Spanish explorer Hernando de Soto. The Army post was officially a subpost of Fort Dade, which was constructed on Egmont Key. These posts were to contain batteries of artillery and mortars to protect Tampa Bay from any invading forces. Construction of Fort De Soto began in November 1898 and completed in 1906. The foundation was constructed of a seashell concrete formula, and the walls and ceiling used a seashell, stone, and concrete mix. The main attractions at the completed post were the artillery and 12-inch coast defense mortar batteries, Batteries Laidley and Bigelow. The post consisted of 29 buildings. The post's features included a large barracks, a hospital, a guardhouse, a blacksmith and carpenter shop, an administration building, and mess hall with kitchen, a bakery, and a storehouse. The site also had brick roads, concrete sidewalks, and a narrow-gauge railroad to aid in moving materials and supplies around the post.
The post was active from 1898 to 1910. At least one company was present at Fort De Soto at all times and many times several units were present. Mosquitoes were a constant problem and the post was very hot in the summers.
In 1910 most troops were moved to Fort Morgan in Alabama. Only a caretaker force remained. By 1914 only an ordnance sergeant and game warden remained at the post. Through most of World War I a larger caretaker force was at the post, usually with about twenty-two privates, two noncommissioned officers, and two commissioned officers. In 1917 four of the post's mortars were disassembled and shipped to Fort Rosecrans in San Diego, California.
In November 1922 the Army announced it would soon close both Forts De Soto and Dade. On May 25, 1923, the forts were officially abandoned, and only one caretaker remained at each post. A number of tropical storms and hurricanes severely damaged the buildings on the post. A few were destroyed, as was Battery Bigelow in 1932. The Army attempted to sell the post, but there was little interest. In September 1938 Pinellas County bought the areas on Mullet Key for $12,500.

Conversion to civilian use

Shortly after Pinellas County purchased Mullet Key from the federal government in 1938, county commissioners granted a lease to Percy L. Roberts for the use of land and buildings on the island the Mullet Key Quarantine Service had once used. The St. Petersburg Times reported the Commission's action in its January 25, 1939, edition:
Lease of Mullet Key buildings to Percy Roberts was ratified Monday by county commissioners who made no change in the tentative lease approved last week.Roberts will pay the county $50 a month for the first year and $100 a month for the next two years for the lease of two buildings on the extreme south end of the county's property on the key.The lessee will operate a daily boat service to the island and will serve fish dinners and rent fishing tackle. The distance from his dock near the Bee Line ferry will be 10 miles. He will land in a sheltered cove on the north end of the island. Trips will be started in about three weeks.

Roberts, a native of St. Petersburg and local plumbing contractor, had a simple business plan. First, run a passenger boat to Mullet Key facilitating access to the isolated island. This service was expected to attract both fishermen and sightseers. For the fishermen, easy access to the pristine fishing waters of lower Tampa Bay; for the sightseers, easy access to the ruins of historic Fort De Soto and the white-sand beaches facing the Gulf of Mexico. Secondly, establish a hotel and restaurant on the island. Roberts envisioned creating a venue on the island appealing to clubs, associations, and other organizations for group outings of members for fishing, sightseeing, and "dining on fried mullet".
With lease in hand and business plan formulated, and with the financial support of Charles R. Carter, a local insurance executive and president of the Bee Line Ferry Co., Roberts immediately began implementing his plan.
For transportation to the isolated island, the passenger boat Hobo was put into service. Hobo operated daily from the Bee Line Ferry Terminal at St. Petersburg's Pinellas Point, pulling away from the dock early morning and leaving for the return trip late afternoon. Hobo was also available for chartered trips in between scheduled runs. "By boat" was not the only means of transportation to the island. A strip of land on the island was cleared in response to requests by some who wanted to fly small aircraft in and out.
Lodging and eating accommodations on the island were fashioned by renovating a building vacated by the Quarantine Service in 1937. The facility at best was austere, but one who was tired and hungry could get a good night's sleep; plenty of coffee, a hearty serving of bacon and eggs for breakfast; any of an assortment of sandwiches for lunch; and, a family style meal of fried mullet with all the trimmings for supper. A screened-in porch was there for those who just wanted to lean back, prop up the feet, enjoy a cool beverage, and relax. This facility became known familiarly as Mullet Key Lodge.
Rubert "Rube" Allyn, a writer for the St. Petersburg Times, included in his March 28, 1939, column, "Along the Waterfront":
When the Pinellas county commissioners leased the old Fort De Soto, and Mullet Key to Percy Roberts, they did a fine thing for the tourists by opening up the vast uninhabited reaches of Mullet Key and the old fort to exploration parties... Today for a nominal fee, one can take a boat at Pinellas Point, and go to Mullet Key, land at the old Quarantine dock, enjoy an old-fashioned fish dinner prepared in the same manner as the pioneers of 50 years ago, by the Roberts family, and explore miles of uninhabited beaches, bayous, and the old Spanish–American War fort...

Bombing range

In less than two years, Mullet Key Lodge became well established and profitable. However, this first for-profit business founded on the island was short-lived. The lease, granted to Roberts in 1939, had to be rescinded because the War Department decided it wanted the island back for use as a bombing range by the U.S. Army Air Corps in support of air bases then being constructed in the Tampa Bay area. That pending transaction was reported by the St. Petersburg Times on December 18, 1940:
Mullet Key purchased by the county from the Treasury department in 1938 for $12,500 will soon be taken over by the United States Army Air Corps for use as a bombing range. The Air Corps will pay the county all that has been expended to date and will pay to Capt. Charles R. Carter all he has expended in improving the building into a fishing lodge. It is understood that Capt. Carter has an investment of about $8,000 while the county’s total investment is about $13,800.

In June 1941, the federal government bought back Mullet Key from Pinellas County for $18,404. As planned, It was turned into a sub-post of MacDill Field and used as a bombing range throughout World War II.

County park

After World War II, the by then-renamed U.S. Army Air Forces had no need for Mullet Key, and it was a sold back to Pinellas County along with adjacent islands Sister Key, Hospital Key, Rattlesnake Key, and Scratch Key. The sale, for $26,495.54, was finalized in 1948. County officials immediately designated Fort De Soto and all of Mullet Key a county recreational area and declared it open to the public. Soon thereafter excursion passenger boats began regularly scheduled trips to the island.
In 1962, a toll road, the Pinellas Bayway, was completed to the mainland, enabling island visitors to arrive by car. On December 21, 1962, Fort De Soto Park opened. On May 11, 1963, Fort De Soto Park was officially dedicated. Its facilities have been expanded over the years. The quartermaster storehouse was reconstructed to become the Quartermaster Storehouse Museum. On December 2, 1977, the Fort De Soto batteries were placed on the National Register of Historic Places. The four 12-inch M1890 mortars and two 6-inch Armstrong guns at Fort De Soto are the only weapons of their type remaining in the United States.
