Borovnica, Slovenia

Peter Bezek of Slovenia sent me this photo of a postage stamp with the viaduct at Borovnica.

This map shows the location of the 340th Bomb Group base at Alesani, Corsica and the town of Borovnica, Yugoslavia. In the B-25s it was a four hour round-trip flight to Borovnica and back.

My dad's crew in B-25J 9V 'Miss Rebel' on December 28, 1944.
This is the crew of B-25J 9V "Miss Rebel" probably taken just after the mission to bomb the railroad viaduct at Borovnica, Yugoslavia on December 28, 1944. Standing from left to right are top-turret gunner, Staff Sgt. William A. Devine; tail gunner, Staff Sgt. Lyle D. Ives; copilot, 2nd Lt. W.E. Steele; bombardier, Theodore G. Constantine; and pilot, 2nd Lt. Edward B. Heilig. Kneeling is my father, radio-gunner, Technical Sgt. Quentin C. Kaiser. 12 planes from the 489th Bomb Squadron and 12 planes from the 486th squadron teamed up to make 340th Bomb Group Mission #665. There was no fighter escort on this mission. The twentyfour planes dropped a total of ninetyfive 1000-pound bombs on the eastern edge of the Borovnica railroad viaduct. The photographic interpretation report summarizes the success of the mission determined by analysis of the target photos. My father's plane, B-25J 9V "Miss Rebel," was in the 5th position of the first box of six planes from the 489th squadron. The #5 and #6 planes were generally equipped with cameras to get pictures of the target. On this mission, my father used a hand-held K-20 camera to photograph the target. His mission photo was taken just as the bombs exploded around the viaduct and the blasts seem to coincide precisely with where they are indicated on the official 340th Bomb Group box score photo. Here's another mission photo my father took which shows how cloudy it was over the target on December 28th and probably explains why another group mission that day returned to base without dropping their bombs.

When Peter Bezek from Slovenia discovered the information about my father's 51st mission on this site he wrote to me and told me the following interesting history of the bridge and sent me the pictures below.

"Here is a short history of Borovnica and the viaduct: Borovnica is a small village or town, 25 km south from Ljubljana, the capitol of Slovenia. In years 1850 to 1857 a 561 meters long and 38 meters high railway viaduct was built on relation Ljubljana - Trieste ( Italy ). - see GM21.jpg and Z61.jpg. 10th of April 1941 - four days after German attack on Yugoslavia - an ex Yugoslav army blew the viaduct up in 226 meters long (somwhere in the middle as you can see in picture GM7.jpg.) In WW2 was Slovenia separated betwen German and Italian ocupators. Borovnica was under Italians and they build a steel constuction over the ruined part of viaduct (see GM6.jpg.) There were several bomb attacks on viaduct in 26th and 27th September 1944. From my information they were RAF attacks from Foggia - Italy. They use Wellington aircraft. I am still working on it so I can't tell you much more. Viaduct was damaged but not ruined." My records indicate that B-17s and possibly other heavy bombers from the the US 15th Air Force bombed the bridge on the 26th, 27th and 29th of September 1944. "In 27th and 28th of December were another bomb attacks on viaduct. These were attacks from your father took pictures. According to your father's log he was there in December 28th. From some people in Borovnica I've found out that there was two attacks - 27th and 28th December. Do you know something about that?" The photographic interpretation report clearly states there were separate missions on the 27th and 28th of December, 1944. The 340th Bombardment Group mission list shows two different missions to bomb Borovnica on December 27, 1944 in addition to the one my father flew on December 28, 1944. "After this attacks viaduct was ruined. After the WW2 a new railway was built around the Borovnica valley. The ruins of the viaduct was destroyed to the ground and only one statue left till today (see bor_048.jpg and z71.jpg.) For viaduct defense enemy had several flak positions on hill Planina - left side and hill Trebelnik - right side all about 500 m higher as viaduct. Viaduct was important because over him was the main railway from harbour Trieste to Ljubljana and further to Germany."

Peter Bezek also sent me the chronological history and pictures of the Borovnica viaduct below. I have inserted excerpts from the USAAF combat chronology where relevant or commented where appropriate using red text.

Peter Bezek sent me this photo showing men working on the Borovnica viaduct.
This picture from Peter Bezek shows local workers under the viaduct at Borovnica. These men may have been from the German Organization TODT which employed over 20,000 laborers to repair the roads and bridges that were repeatedly bombed by the 12th Air Force.
