Video says movie is Down Mexico Way. Wrong. That was 1941. 1939 movie was South of the Border. Per TCM release date was 12/15.
*From Battle Off Uruguay, the final editorial.
The pocket battleships mount six eleven-inch guns, but in only two turrets, which means that only two of the British ships could be kept under fire from the Spees main battery simultaneously. To punish her third attacker the Spee must have been forced to shift fire frequently from one ship to another a process which is distracting to accurate and rapid gunnery, and which, of course, reduced the weight of fire to which each British ship was subjected.
Now thats informative! (To me, anyhow.)
