Now, solve this: Question: How many people have received the medal that Lance Corporal Donald Hogan was posthumously awarded for his actions on August 26th? Passage:In 2009 the Taliban began moving even more men into Nawa, possibly for additional attacks against Lashkar Gah. On May 13, they launched an attack against the Afghan National Police in the district, that overwhelmed several posts. By late spring they had established a solid foothold in the district. On July 2, 2009, Marines from the 1st Battalion, 5th Marines (1/5) occupied the district as part of Operation Strike of the Sword. They set up their headquarters in Forward Operating Base Geronimo. On August 26, Lance Corporal Donald Hogan, a Marine with 1/5, threw himself in front of an improvised explosive device (IED), saving the Marines in his squad. He was later posthumously awarded the Navy Cross for his actions. In December, 1/5 was replaced by 1st Battalion, 3rd Marines. In the late summer and early fall the Marines detained Haji Adam, one of Nawa's main drug lords, and turned his house into Combat Outpost (COP) Sullivan. In November two local officials were assassinated. On December 17, Admiral Mike Mullen, the Chairman of the Joint Chiefs of Staff, visited Patrol Base Jaker and touted the security gains by touring the Nawa district center without wearing body armor. Several weeks later Afghan President Hamid Karzai and ISAF commander General Stanley McChrystal also visited Nawa on January 2, 2010. On January 9 British journalist Rupert Hamer and two Marines were killed by an IED in the district.
