hello captain pete here, with permission while at the old Texaco site in Bayonne, N.J., around 1995 I was looking for some remains of a rev war fort, and pre-rev war ferry house.
Texaco was in the process of reclaiming the land covered over when it became a fuel oil storage facility about 1906. In what was approximately the center of their property they removed 3 large oil tanks. The middle one was covering a dug well which probably was part of the ferry owners land. I found broken pottery and glassware bits. Nothing else with my detector. While working towards the Kill Van Kull shoreline, I did find a cannon ball which was the size of a baseball, in very rusted condition. This came out of a test pit that Texaco dug for soil samples. I have some old records that report of the Hessians & British firing on the fort at Bergen Point. Doctor Robinson (our old local historian) has some interesting maps and stories about this old Rev-War fort and Fort Delancy, another fort located in what is now uptown Bayonne, N.J. I have to sign out now, but will come back with more precise information on this subject.
