WHY THE TITLE "GLOBE and ANCHOR"?
Many have asked why I don't say, eagle, globe and anchor, implying that I have erred. No error, it reads as I intended. Apparently unknown to most Marines of today, there was a time in the Corps when Marines referred to their emblem (emblem not an "ega"--but that's yet another story) as simply the Globe and Anchor, and there are still some old timers and writers around who will still use that term.
There are many writings available, most of them older writings, but some more recent, where you will find this. One of the best examples of this, perhaps, may be--and there are many more--a quote in the recent book by Colonel Jon T. Hoffman, USMCR, Chesty. It reads as follows:
"Colonel Robert D. Heinl, the premier historian of the Old Corps and a former subordinate of Puller, believed that Chesty was one of the greatest raconteurs that ever wore the Globe and Anchor."
(Random House, 2001, Preface, page xi)
This was a common expression even in this old boot's first days in the Corps of the early 1950s. I find the term similar to the term used by the Royal Marines for their emblem, known as the Globe and Laurel.
Matter of fact, I do not recall the emblem being specifically referred to as an eagle, globe and anchor until the late 50s or early 1960s, on TV recruiting promotions, ads, etc.
To be sure, the popular term has now become eagle, globe and anchor, and the majority considers anything they are not used to, to be incorrect. As for this Marine, as always, I'll fall in w/the old salts!
