NO COMPROMISE!

From military.com Internet web site and the article courtesy "We Are The Mighty | By Blake Stilwell." A thanks to Ken for the tip. Consider this one a new one for me.

"The Intense Rules for US Marines Who Protected Mail from Gangsters"

"'When our Corps [USMC] goes in as guards over the mail, that mail must be delivered,' wrote Secretary of the Navy Edwin Denby. 'Or there must be a Marine dead at the post of duty. There can be no compromise.' It was the Golden Age of the Gangster, when bank robbers were folk heroes, cheered on by citizens who were suffering under the weight of Prohibition and the Great Depression. But when the mail started getting robbed by these hoods, the Postmaster General asked President Harding to send in the Marines."

ONE-HUNDRED YEARS AGO LARGE BULK SHIPMENTS OF MAIL AND OTHER GOODS ALMOST EXCLUSIVELY SHIPPED BY THE RAILROADS. A FAVORITE TARGET OR ORGANIZED CRIME AND CRIMINAL ENTERPRISES. GANGSTERS POSSESSING AND NOT HESITATING TO USE HEAVY WEAPONS TO ACHIEVE THEIR GOALS.

Marine Corps always ready to prove their mettle and in this case were successful.
