I just found out my Swedish great great grandpa fought in Serbian army during WW1

Hello from Svenska friends!So i was recently visiting my family in Terråk and during lunchtime conversation about history and WW1 (i have no idea how we reached that topic though) my grandpa told me a story about my great great grandpa, Nikodemus, and how he fought alongside Serbs in Serbian army during WW1. He told me that the reason why Nikodemus joined Serbian army is because during his visit to Constantinople back in the 1900s (it was a business trip, he was a geographer, but not so well known unfortunately), he stayed in Belgrad, Serbia (Kingdom of Serbia back then i guess?) and fell in love with one waitress. He didn’t want to leave her but she also refused to go with him. My grandpa said that the he doesn’t remember the reason why she didn’t want to come with Nikodemus, but said that he fell in love with her so much that he paid for her photo to be made and carried with him at all times. I guess photographs were costly back then, haha.Anyway, when he returned to from Constantinople to Belgrad, he tried to find her, but the owner of the pub (or hotel, bar?) said that she left the work to go back to her village. Disappointed, he went back to Sweden but never forgot about her.Couple of years went by and WW1 started. He felt sorry for Serbian people who he met while he was over there and described them as one of the most kind and welcoming people that he ever met (mind you, he visited A LOT of countries). He decided to go to Serbia to offer help to logistics and didn’t plan to grab the rifle because he was a pacifist, but after he arrived he got familiar with the situation. True or not, he said that Austrians hanged Serb woman, children as well and fed them to the dogs. He was terrified and decided to join Serbian army in their battle. My grandpa doesn’t know exactly which battles Nikodemus fought, but knows that he fought somewhere in the western Serbia. He also said that he went through Albania, through retreat i assume, with Serbian soldiers and that he pushed together with Serbian army during their counter offensive.After the war, he remained for some time in Serbia trying to find the girl he loved, but unfortunately, he never did manage to find her. He later returned to Sweden and eventually found Swedish girl, got married, had kids, etc. So yeah, one interesting story from my life. I’m glad to have the opportunity to share it with you guys. Unfortunately, i don’t have any photos of Nikodemus, let alone the photo of that girl, because i would love to share it with you.Love from Sweden! xx via /r/serbia https://ift.tt/3J7fk1Q
