Quoting Edward B. Westermann’s Drunk on Genocide, page 194:

[A] mass execution of more than eight thousand Jewish men, women, and children at Słonim on November 14, 1941, was led by SS and auxiliary forces but also included a number of volunteers from a nearby infantry unit. A former soldier described the killings, during which his peers drank heavily and “held up Jewish infants in the air and shot them with pistols.”

Another soldier remembered the murders as a “real massacre,” and he observed, “The shooting was somewhat haphazard [and] the shooting commandos were very drunk.”⁹⁸ In this case, the consumption of alcohol during a daylong massacre appears to have played multiple rôles for the soldiers involved.

Pages 136–7:

Alfred Metzner participated in the mass execution of Jews from the Słonim ghetto.¹⁰⁷ He recalled that “the troops were well supplied with schnapps and cigarettes to ensure an orderly conduct of the task.”¹⁰⁸

After the conclusion of the day’s massacre, the district commissar, Gerhard Erren, held a debriefing with the killers during which he “praised many men and reprimanded the weak who were told to do better in the future. […] After the debriefing, they drank and celebrated. The total dead for the day was between four and eight thousand Jews, including men, women, and children.”¹⁰⁹

Over the course of the next seven months, these men continued their murderous rampage with “lots of schnapps” to “stimulate their work zeal.”¹¹⁰

In his postwar testimony, Metzner detailed the “final solution to the Jewish problem” in Slonim, including the liquidation of the ghetto and the murder of as many as ten thousand men, women, and children. The ordeal for the ghetto inhabitants began on the night before the planned massacre, as [Axis] and auxiliary policemen entered the ghetto and sexually assaulted Jewish women, with some of the men “boasting” of the number of women they had “used in this way trying to outdo” their colleagues.¹¹¹

The major killing began at four the following morning as the policemen drove Jews out of their houses or shot them inside. Tellingly, some of the perpetrators chose to use tracer ammunition to kill their victims, a round that inflicted especially large wounds and could set fires to wooden structures. According to Metzner, the continuous distribution of schnapps sustained the “murderous courage” (Angriffsmut) of the killers, who finished the massacre at 10 p.m., completing an eighteen‐hour murder orgy.

Despite being “fully covered in blood,” the men gathered for the usual post‐massacre debriefing, and Metzner stated, “At the same time, the annihilation [of the ghetto] was celebrated with schnapps and I was praised [by the district administrator].”¹¹²

Page 186:

Sergeant Erich Aichinger took at least two Jewish “girlfriends” during his time in Słonim. The girls lived with him in his room, and at least one of them routinely served alcohol at gatherings of local [Axis] officials. Despite his relationship with the women, Aichinger watched as one of his “girlfriends” and her mother were killed during the liquidation of the local ghetto. In order to be able to watch the execution, Aichinger allegedly drank so much at the massacre site that he was warned to stop.⁵⁴

Martin Dean’s Collaboration in the Holocaust: Crimes of the Local Police in Belorussia and Ukraine, 1941–44, page 50:

One Jewish survivor was prevented from returning to his home, after visiting a friend the night before, as the [Axis] forces had already cordoned off the ghetto. He described what he was able to observe from the loft of his friend’s house:

I saw German soldiers chasing people and beating them and also children being thrown to the ground. These people were screaming. I later heard the sound of engines coming from the direction of the old market place. Shortly after that everything went quiet. It remained quiet for about two hours. Then things returned to normal — shops opened and people came back out onto the streets.⁶²

He never saw his mother, his father, his brother and his own child again.

This action was a joint operation between the District Commissar, Gerhard Erren, and the Security Police, assisted by the Wehrmacht, Latvian and Lithuanian police auxiliaries and the local Belorussian police:

1935: After lengthy argument Berlin published a supplement to the German Citizenship law, which laid down that Germans with two Jewish grandparents, were Orthodox Jews, were married to Jews, or were the offspring of a marriage with a Jew, were legally ‘Jewish’. (Those who had only one Jewish parent or grandparent remained German citizens…for now.) Thus, those who were either legally or traditionally Jewish lost their voting rights and the right to hold public office, even if they were WWI veterans.
1938: Rome commissioned Artigliere into service.
1939: Around the same time that Tōkyō dismissed Kenkichi Ueda from the Army General Staff, Berlin added the Netherlands back to its invasion plan for Western Europe as the Luftwaffe stressed the importance of having airfields in the Netherlands, and Berlin named Theodor Eicke the commander of all SS Death’s Head units; Richard Glucks was to take over Eicke’s former position as the concentration camps’ inspector. In Vienna, Austrian detachments of the SS‐Verfügungstruppe placed stocks of hand grenades at synagogues to set them on fire.
1940: The Imperialists assigned Kamoi to the 24th Air Flotilla and Axis bombers raided Alexandria, Egypt, sinking Egyptian steamer Zamzam, but as Greek troops began to cross into Albanian borders, the Axis suffered its first land defeat of the war. A massive night time raid on Coventry, England by 437 He 111 bombers, dubbed Operation Moonlight Sonata, massacred 568, injured 863, and destroyed 60,000 buildings (including the city’s 14th Century cathedral) with 450 tons of high explosive bombs, fifty parachute bombs, and 36,000 incendiary bombs; the Axis lost only one bomber.
1941: Axis torpedo damage from yesterday successfully took out HMS Ark Royal, Axis submarine U‐561 sank Panamanian ship Crusader in the North Atlantic, massacring 33 and leaving only one alive. Comandante Cappellini conducted a trial out of La Pallice, and Morosini successfully departed Bordeaux for Le Verdon‐sur‐Mer only after the heavy fog passed. Tatsuta Maru departed Yokohama and Kaga exited the drydocks at Sasebo Naval Shipyard around the same time that Tōkyō relieved Shokaku of her status as the flagship of Carrier Division 5.
1942: Axis submarine facilities at Saint Nazaire suffered a bombing raid, but two transports containing a total of 2,500 Jews from Poland’s Ciechanow ghetti arrived at Auschwitz Concentration Camp; 633 men and 135 were registered into the camp, and the remaining 1,732 were massacred in gas chambers. On the same day, 1,500 Jews from Bialystok District 2 in Poland arrived at the same camp; 82 men and 379 women were registered into the camp, and the remaining 839 were massacred in gas chambers. Finally, the SS doctors of Auschwitz Concentration Camp sent 110 prisoners from the Auschwitz I hospital to Birkenau Concentration Camp to be massacred in the gas chambers. In East Asia, the Kinkaseki Prisoners of War Camp opened, and the Taihoku Prisoners of War Camp № 6 near Taihoku (now Taipei) opened; on the same day, British prisoners of war from Singapore arrived on Taiwan via Kirun (now Keelung), destined for this camp.
1943: Destroyer Yukikaze departed Kure, Japan to escort transport Irako to Truk, Caroline Islands; Irako departed Yokosuka, Japan at 1400 hours in convoy № 3115.
1944: Horst Wessel and Albert Leo Schlageter sailed in rough waters near Rügen: Albert Leo Schlageter struck a mine, damaging its starboard bow, so Horst Wessel took Albert Leo Schlageter in a stern tow to prevent Albert Leo Schlageter from sinking. In the Kurile Islands, the Axis lost a small vessel to Allied fire.
