He was not awarded any Purple Hearts while in Vietnam in 66. He did "apply" for Purple Hearts in 1968 when he was in politics.
So he applied for them after he was already back in the States? How many did he get going that route? Do guys like him have no shame? And then you have awesome men and women like Lt.Col. Ollie North who got his first two for wounds received in combat, and then declined THREE MORE Purple Hearts so he could stay in Nam and fight! What a difference between North and Murtha.
