If war wasn't scary enough already, living enemies might not be the only ones you have to worry about. You see, where there's war, there's death, and where there's death, there are ghosts...or ghost stories, at least! There are dozens, if not hundreds, of unique, ghostly experiences from veterans and bases all over the world. These creepy stories might leave you checking over your shoulder twice when you walk down the hall at night!

Ghost Planes

During and after World War II, fighter planes were seen patrolling the sky appearing and disappearing in and out of the clouds. One such sighting happened a year after Pearl Harbor. When the United States Army radar traced the signal of an incoming plane, pilots were dispatched to investigate.

An American P-40 was spotted, riddled with bullet holes, its landing gear, mangled, and its blood drenched pilot slumped in his harness. Suddenly, the aircraft fell from the sky spiraling out of control and crashing down. When scouts went to investigate, the P-40 was found, but the pilot had disappeared.

Diplomat Hotel

Nights at the Diplomat Hotel are often pierced with shrill screams and banging. Located in the Philippines, it is a hot spot for paranormal investigation. The hotel's terror is believed to have stemmed from the Japanese invasion of the Philippines. Originally a monastery, invading soldiers beheaded all nuns and clergymen, leaving a trail of blood in their wake. For the remainder of the war, it served as a sanitorium, only to reopen again as the Diplomat Hotel, where guests often see black figures and women clothed in white.

The Battle of the Alamo

The 1836 Battle of the Alamo was the climatic point of Texans' fight for independence from Mexican control. Today, the San Antonio historic landmark now serves as a cemetery for the remains of fallen soldiers, many of whose bodies were dismembered and dumped into the San Antonio River. Just days after the battle, though, paranormal activity was reported. When Mexican General Juan Jose Andrade ordered the burning of what remains still lay on the field of battle to prevent the spread of disease, the men came running back, fearful of what they'd witnessed. On the river, the men had spotted six diablos or "devils," guarding the front of the Alamo mission. Over the years, visitors have seen young boys running along the mission plaza and then disappearing, hearing the clacking of horse hooves on the streets, and even seeing a man and small boy fall from the roof of the mission.

The Jefferson Barracks 

On October 23, 1826, the Jefferson Barracks were opened in honor of president Thomas Jefferson who had passed earlier that year. It's been used as a hospital, cemetery, and also for military staging,but on the barracks headquarters, soldiers have reported an aggressive sentry confronting them. He's said to approach with a bloody bullet hole through his head. Supposedly, the sentry had been killed in a munitions raid and as he believes he's still on duty, confronts those he suspects as the enemy.

Missing Children

Though Switzerland tried to stay neutral during WW2, the country was repeatedly swayed by both Allied and Axis powers. When Germany instigated, the UK retaliated, sending one British unit to a secluded village within the Swiss Alps. However, just a few weeks after their arrival, scraps of food supplies started disappearing and goods were stolen. Not long after, children went missing from the village, including one Private Reginald from the British troop. These disappearances led to the story that a monster resided in the mountains.

One night, soldiers on patrol saw a figure through the window of a house. The figure gave chase all the way to the outskirts of the village where the figure jumped into a man-made cave. Shots were fired from either side and after a resounding silence, soldiers entered the cave where they found Reginald with a bullet whole through his heart and surrounded by the missing children's half-eaten bodies.
