CORRECTION
The battlefield at Gettysburg, Pennsylvania, resulted in 50,000 Union and Confederate troops killed, injured, or captured during the Civil War. The original version of this post mistakenly stated that these were all KIAs.
Marcy Borders died in August 2015, a year after being diagnosed with stomach cancer. An original version of this post suggested that her illness was the result of exposure from 9/11 events, a fact we could not confirm. Likewise, a line was also cut from an original version that suggested exposure as the cause of hundreds of more deaths in the years following 9/11, a fact we could not confirm.
UPDATE
Terri Gurrola's name has been changed to her full title, "Maj. Terri Gurrola, U.S. Army, PA-C."
