Pollepel Island is a uninhabited island in the Hudson River in New York. The principal feature on the island is Bannerman's Castle, an abandoned military surplus warehouse. Description Pollepel Island has been called many different names, including Pollopel Island, Pollopel's Island, Bannerman's Island, and Bannermans' Island. Pollepel is a Dutch word meaning "(pot) ladle" The island is about north of New York City and about from the Hudson River's eastern bank. It covers about , most of it rock. Early history Pollepel Island was encountered by the Europeans during the first navigation of the Hudson River by early Dutch settlers in the Province of New York, at the "Northern Gate" of the Hudson Highlands. During the Revolutionary War, patriots attempted to prevent the British from passing upriver by emplacing 106 chevaux de frise (upright logs tipped with iron points) between the island and Plum Point across the river (see Hudson River Chains). Caissons from several chevaux de frise still rest at the river bottom. Still, these obstructions did not stop a British flotilla from burning Kingston in 1777. General George Washington later signed a plan to use the island as a military prison; however, there is no evidence that a prison was ever built there.

In 1867 the business occupied a ship chandlery on Atlantic Avenue engaged in the purchase of worn rope for papermaking. The store on the 500-block of Broadway opened in 1897 to outfit volunteers for the Spanish–American War. The business bought weapons directly from the Spanish government before it evacuated Cuba; and then purchased over 90 percent of the Spanish guns, ammunition, and equipment captured by the United States military and auctioned off by the United States government. Bannerman's illustrated mail order catalog expanded to 300 pages; and became a reference for collectors of antique military equipment. Bannerman purchased Pollepel island in November 1900, for use as a storage facility for his growing surplus business. Because his storeroom in
