that around 16:00 he arrived in the yard where the German soldiers had been shot, and that he "saw 15 or 16 dead and wounded German soldiers lying along the wall". He noted that some of the wounded soldiers were still moving, but he did not examine any of them. He answered "Yes, sir" when asked if he was the surgeon of the 3rd Battalion, 157th Infantry, at that time, and did not know if any medical attention was called for the wounded. According to Buechner's 1986 book, Dachau: The Hour of the Avenger: An Eyewitness Account, U.S. forces killed 520 German soldiers, including 346 killed on the orders of 1st Lt. Jack Bushyhead, in an alleged mass execution in the coal yard several hours after the first hospital shooting. Buechner did not witness the alleged incident, and his sworn testimony was that he "saw 15 or 16 dead and wounded German soldiers lying along the wall." His sworn testimony in the official investigation report also did not include any mention of a second shooting. David L. Israel disputed this account in his book The Day the Thunderbird Cried: Jürgen Zarusky also concluded that Buechner's claims were incorrect. Other accounts Abram Sachar reported, "Some of the Nazis were rounded up and summarily executed along with the guard dogs." According to Jürgen Zarusky (originally published in a 1997 article in Dachauer Hefte), 16 SS men were shot in the coal yard (one more killed by a camp inmate), 17 at Tower B, and perhaps a few more killed by U.S. soldiers in the incident. Anywhere from a few to 25 or 50 more were killed by inmates. Zarusky's research makes use of the detailed interrogation records contained in Whitaker's official May 1945 investigation report, which became accessible in 1992, as well as a collection of documents compiled by General Henning Linden's son. The Dachau liberation reprisals were documented among others by U.S. Army photographers Paul Averitt, George Gaberlavage, Sidney Rachlin and Ed Royce, Sr. Killings by the inmates Walenty Lenarczyk, a prisoner at Dachau, stated that following the camp's liberation "prisoners swarmed over the wire and grabbed the Americans and lifted them to their shoulders... other prisoners caught the SS men... The first SS man elbowed one or two prisoners out of his way, but the courage of the prisoners mounted, they knocked them down and nobody could see whether they
