British
heavy cruiser HMS Exeter, light cruiser HMS Ajax, and New Zealand
light cruiser HMNZS Achilles (Commodore Henry H. Harwood, RN, flag in Ajax),
which had rendezvoused the previous day, engage German armored ship Admiral
Graf Spee in the Battle of the River Plate. The "pocket
battleship" knocks Exeter out of action and damages her consorts,
but is compelled by the damage inflicted by her lesser‑gunned adversaries
(which are fought, as First Lord of the Admiralty Winston S. Churchill writes,
"with the utmost resolution and skill") to retire toward Montevideo,
Uruguay. Exeter, badly damaged, withdraws to the Falkland Islands (see
14 December.). The U.S. Navy studies the Battle of the River Plate from a
perspective of drilling gunners to maintain fire by local (rather than a
centralized director) control. To this end, a scenario similar to the River
Plate engagement is included in an exercise in 1940. In addition, the Director
of Fleet Training considers the "proper use of smoke either as a defense
measure or as a means of covering movements of an attacking force"
extremely important, and points out the demonstrable effectiveness of a smoke
screen "as a means of protection for light forces" employed by
Commodore Harwood in the battle with Admiral Graf Spee.
U.S. freighter Exochorda,
detained at Gibraltar by British authorities since 5 December, is released.

Heavy cruiser Vincennes
(CA‑44) and destroyers Evans (DD‑78) and Twiggs (DD‑127) (the
latter destroyer having shadowed British destroyer HMS Hereward a short
time before) trail Australian light cruiser HMAS Perth which is prowling
the Gulf of Yucatan waiting for the emergence of German passenger liner Columbus.
The Americans maintain such a close and persistent surveillance of the
Australian warship that Perth's commanding officer, Captain Harold B.
Farncomb, RAN, is said to have remarked in exasperation, "Queer idea of
'neutrality' these Americans have!" German freighter Arauca departs
Vera Cruz, Mexico, followed subsequently by passenger liner Columbus, the
third largest ship in Germany's merchant marine. Destroyer Benham (DD‑397),
soon joined by destroyer Lang (DD‑399), trails Columbus. A
succession of U.S. ships will, over ensuing days, send out plain‑language
position reports (see 15‑20 December).
German armored ship Admiral
Graf Spee puts in to Montevideo, Uruguay, for repairs. British light
cruiser HMS Ajax and New Zealand light cruiser HMNZS Achilles maintain
patrol off the 120‑mile wide River Plate estuary. British heavy cruiser HMS Cumberland
reinforces Ajax and Achilles that night.

Lang steam to join destroyer Davis (DD‑395) in attempting to
locate freighter Arauca. Schenck soon proceeds on other assigned duties.
