The USS CACAPON seems to have used only the double-circle general purpose hand cancel to cancel mail during OPERATION HIGHJUMP (figure 1) and almost 100% of the cancels are dated 30 JAN 1947. A few other dates are known, i.e. 2 DEC 1946 and 23 APR 1947 of this type cancel.

However, one cover is known with a relative date but with a new type single-circle cancel. This appears to be a back-dated cancel at the request of W.G. Crosby as no Crosby covers managed to reach this ship before departure for the Antarctic (figures 2 and 3).

No rubber-stamp return addresses or specific cachets related to this ship are known to this writer.
