 In keeping with the idea that all enrolled students and " former students " comprise a family ( the term alumni is not generally used , as " former students " include those who could not complete their education , such as those who entered military service ) , Aggies have created two traditions to honor members of the Aggie family who have died . Aggie Muster is held annually on the anniversary of the Battle of San Jacinto , April 21 , to honor the death during the previous year of any enrolled student or alumni . Over 300 Musters are held around the world , with the largest taking place at Reed Arena on the Texas A & M University campus . All Muster ceremonies feature the Roll Call for the Absent . As the names of the deceased Aggies are called , a family member or friend answers " Here " and lights a candle , to symbolize that although their loved one is not present in body , his or her spirit will shine forever . The event received worldwide attention during World War II , when 25 Aggies " mustered " during the battle for the island of Corregidor .
