Problems with Z-buffer.

I have been working on a flight sim that loads in several
rectangular patches of terrain. The problem is that the z-buffer
works correctly for the elements of each patch individually but
not between the elements of two different patches. I apologize
if I'm not being very clear, I'll give an example. If I have two
patches A and B (each of them made up of a few thousand
polygons) with A being closer to the viewer than B. All of
the polygons in A have been rendered properly with respect
to each other, all of the polygons of B have been rendered
properly with respect to each other. However parts of B
that should be hidden behind A, are drawn as though they
are nearer. This only happens to part of B, the rest of it is
behind A, like it should be. I am loading all of the patches
at the same time and they are all children of one DCS node.
I would appreciate any help you can offer. Thanks.
