I think it means something as well.
Have I not conveyed? = I am conveying or I have conveyed. conveyed...conveyed..conveyed

I’m thinking it pertains to transport of materials necessary for an attack. To convey means to transfer. Either he is ordering the transport of the materials into position, or indicating that the materials have already been “conveyed” and are ready for launch.
IMHO of course.
