Deep Einstein X-ray imagery of the Small Magellanic CloudDeep Einstein IPC imagery of about 50 percent of the main body and 'wing' of the SMC has been obtained and analyzed. The four X-ray images have exposure times between 12,000 and 24,000 s and reveal a total of 25 X-ray sources. Twelve of these sources are new detections. Two, possibly three, sources with soft spectra may be newly discovered supernova remnants. The rest of the sources have harder spectra and intrinsic X-ray luminosities in the range log L(x) = 34.0-35.0 and are most likely stellar objects in the SMC. These luminosities are much lower than that found for typical Galactic X-ray binaries, and a factor of 100 larger than the range for 'normal' galactic O and B stars.
