Let's say a general war erupts between Germany and Great Britain over the
Second Samoan Civil War in December 1899. (Close enough to the cut off for this thread)
For Detail: The Tripartite Convention is delayed, and the December 11th "hammer and anvil" speech by Foreign Sec. Bernhard von Bulow spurs both him, the Kaiser, and the Reichstag to escalate the conflict with an isolated Britain specifically.
Who wins and what could be plausibly gained by the victor?
I know the German navy had just commissed 3 additional battleships that year and the position of the economy was quite strong at that point but I'm not sure.

Edit: So I have a German tactical win for three reasons.
1. The British were busy fighting the Boers and may under estimate the ability of the small but manuverable German navy under Admiral Tirpitz. (but that doesnt mean a turn of the century Sealion of course)
2. The German economy would have the material advantage and could simply sit back and outproduce.
3. The colonial german army in Tanzania could march against British territories in Africa and may even partner up with the Boer insurrection in the south.
