Problem: The 4th Bulgarian Army held the most important position for the conquest of Serbian Macedonia. The fighting began on 29-30 June 1913, between the 4th Bulgarian Army and the 1st and 3rd Serbian armies, first along the Zletovska and then after a Bulgarian retreat, along the Bregalnica. Internal confusions led to heavy Bulgarian losses in 1-3 July. The Serbs captured the whole 7th Division of the 4th Bulgarian Army, without any fight. By 8 July, the Bulgarian Army had been severely defeated. On the north the Bulgarians started to advance towards the Serbian border town of Pirot and forced Serbian Command to send reinforcements to the 2nd Army defending Pirot and Nis. This enabled Bulgarians to stop the Serbian offensive in Macedonia at Kalimanci on 18 July. On 13 July 1913, General Mihail Savov assumed control of the 4th and 5th Bulgarian armies. The Bulgarians dug into strong positions around the village of Kalimantsi, at the Bregalnica river in the northeastern Macedonia region. On 18 July, the Serbian 3rd army attacked, closing in on Bulgarian positions. The Bulgarians held firm, the artillery was very successful in breaking up the Serb attacks. If the Serbs had broken through the Bulgarian defences, they might have doomed the 2nd Bulgarian Army and driven out the Bulgarians entirely out of Macedonia. The defensive victory, along with the successes to the north of the 1st and 3rd armies, protected western Bulgaria from a Serbian invasion. Although this boosted the Bulgarians, the situation was critical in the south, with the Greek Army.

Problem: The term "Red October" has also been used to describe the events of the month. This name has in turn been lent to a steel factory made notable by the Battle of Stalingrad, a Moscow sweets factory that is well known in Russia, and a fictional Soviet submarine. Ten Days That Shook the World, a book written by American journalist John Reed and first published in 1919, gives a firsthand exposition of the events. Reed died in 1920, shortly after the book was finished. Dmitri Shostakovich wrote his Symphony No. 2 in B major, Op. 14 and subtitled To October, for the 10th anniversary of the October Revolution. The choral finale of the work, "To October", is set to a text by Alexander Bezymensky, which praises Lenin and the revolution. The Symphony No. 2 was first performed by the Leningrad Philharmonic Orchestra and the Academy Capella Choir under the direction of Nikolai Malko, on 5 November 1927. Sergei Eisenstein and Grigori Aleksandrov's film October: Ten Days That Shook the World, first released on 20 January 1928 in the USSR and on 2 November 1928 in New York City, describes and glorifies the revolution and was commissioned to commemorate the event. 7 November, the anniversary of the October Revolution, was the official national day of the Soviet Union from 1918 onward and still is a public holiday in Belarus and the breakaway territory of Transnistria. The October revolution of 1917 also marks the inception of the first communist government in Russia, and thus the first large-scale socialist state in world history. After this Russia became the Russian SFSR and later part of the USSR, which dissolved in late 1991.

Problem: In 1929, the Columbia Broadcasting System began making regular radio news broadcastsfive-minute summaries taken from reports from the United Press, one of the three wire services that supplied newspapers with national and international news. In December 1930 CBS chief William S. Paley hired journalist Paul W. White away from United Press as CBS's news editor. Paley put the radio network's news operation at the same level as entertainment, and authorized White to interrupt programming if events warranted. Along with other networks, CBS chafed at the breaking news embargo imposed upon radio by the wire services, which prevented them from using bulletins until they first appeared in print. CBS disregarded an embargo when it broke the story of the Lindbergh kidnapping in 1932, using live on-the-air reporting. Radio networks scooped print outlets with news of the 1932 presidential election.:485-486 In March 1933, White was named vice president and general manager in charge of news at CBS. As the first head of CBS News, he began to build an organization that soon established a legendary reputation.:486 In 1935, White hired Edward R. Murrow, and sent him to London in 1937 to run CBS Radio's European operation.:486 White led a staff that would come to include Charles Collingwood, William L. Shirer, Eric Sevareid, Bill Downs, John Charles Daly, Joseph C. Harsch:501 Cecil Brown, Elmer Davis, Quincy Howe, H. V. Kaltenborn, Robert Trout, and Lewis Shollenberger. "CBS was getting its ducks in a row for the biggest news story in history, World War II", wrote radio historian John Dunning.:487
