MILWAUKEE (CBS 58) -- Congresswoman Gwen Moore released a statement informing the passing of Milwaukee World War II (WWII) veteran Anna Mae Robertson. 

Robertson served in the Six Triple Eight Central Postal Directory Battalion during WWII or 6888th, helping connect people with their loved ones via letters. 

"Their selfless service played a crucial role in boosting morale during WWII," Congresswoman Moore said in the statement. "The story of the Six Triple Eight Battalion has since inspired Americans across the country." 

The 6888th Battalion was the only woman of color unit to serve overseas.

According to the National Parks Service, by 1945 multiple warehouses in Birmingham, England had mail written by soldiers which hadn't been distributed - with a backlog of six months. Even with backlash and slander, the women of the battalion lived by the motto "no mail, low morale," and focused on getting the letters to soldiers and their families. In February 1946, the unit was sent back to the United States having received no welcoming ceremony. 

"I am honored to have championed legislation to award Six Triple Eight members a Congressional Gold Medal," said Congresswoman Moore. "After receiving the Congressional Gold Medal and national recognition decades after her heroic service, I am thankful that my constituent, Ms. Robertson, was able to receive her flowers while she could still smell them."

Robertson was originally from Arkansas, but established roots in Milwaukee when she moved here. 

"I join our community in mourning her loss and remembering her trailblazing legacy," said the statement.
