During WWII, The Nazis threatened to invade Switzerland through
diplomatic means.  That is, the German ambassador told the Swiss
ambassador that he would overrun Switzerland's 1 million citizens with
2 million troops.  The Swiss ambassador, unabashed, replied with a
quip something along the lines of "Then I will instruct my citizens to
shoot twice."

I would like to know:
a) the precise facts of this story
b) the names of the ambassadors
c) the quoted conversation between the two ambassadors, verbatim (I
clearly do not have the quote correct or the story precisely right).

p.s.  This is unrelated to my Swiss question above, but I wanted to
make sure pinkfreud read my comment on my last answered question

I am posting this as a comment because you seem to be seeking solid
"verbatim" evidence about the story. I am unable to provide that.
Perhaps another researcher will locate such information.

Although there are quite a few web sites that relate this anecdote to
World War II, many if not more, actually claim this as a World War
I-era event.

According to Stephen P. Halbrook, author of a book called "Target
Switzerland," the story is as follows:
"Shortly before World War I, the German Kaiser was the guest of the
Swiss government to observe military maneuvers. The Kaiser asked a
Swiss militiaman: 'You are 500,000 and you shoot well, but if we
attack with 1,000,000 men what will you do?' The soldier replied: 'We
will shoot twice and go home.'"

A web page about the Swiss military museum at Morges mentions a 1914
postcard that depicts the story.

'"Shoot twice" - the caption on a Swiss postcard of 1914, depicting a
Swiss militia man being asked by the Kaiser what the Swiss would do if
he sent an army of half a million Germans against the quarter million
Swiss Army.'

Of course, even if this 1914 postcard exists, it doesn't necessarily
prove that story is true.  It still might have been just a legend.

The military maneuvers, mentioned in the previous comment by
juggler-ga, took place in September 1912 and are referred to as
"Kaisermanöver 1912":
