Point taken but as Martins Hundred shows they could have used triangular 
bastions which were well established on the Continent. The fort design 
at Jamestown was clearly chosen- they must have known all about the 
theory of triangular bastions at this date from both military books and 
experience- and they were presumably geared as long suggested to firing 
at Spanish shipping
