AUGUSTA — While volunteers placed wreaths from Maine on tombstones at Arlington National Cemetery on Saturday, hundreds of Mainers fanned out across veterans’ cemeteries in and around Augusta, some of them with shovels to excavate the headstones buried under crusty billows of snow. At each grave, they left a single evergreen wreath decorated with a bow, then took a moment to remember the person whose remains rested there. William Deetjen of Camden went to the Maine Veterans Memorial Cemetery off Civic Center Drive with his family and left wreaths for his grandparents, all of whom are buried there. Both of Deetjen’s grandfathers were veterans who served in Europe – one in the Navy during World War I and the other in the Army during World War II.
