SOUTHPORT — Dennis Andrews had to wait 45 years to replace the missing Bronze Star he earned while serving in Vietnam, but when he finally received it on Saturday, hundreds were looking on and applauding at the Southport Town Hall. “It was overwhelming,” said Andrews, 67, of Boothbay Center, his eyes misting over. Andrews attended the Welcome Home Veterans event hosted by local author Sarah Sherman McGrail to honor veterans from the Vietnam and Korean wars.
