Dive bomberA dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even en masse. After World War II, the rise of precision-guided munitions and improved anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing.
Reconnaissance aircraftA reconnaissance aircraft (colloquially, a spy plane) is a military aircraft designed or adapted to perform aerial reconnaissance with roles including collection of (including using photography), signals intelligence, as well as measurement and signature intelligence. Modern technology has also enabled some aircraft and UAVs to carry out real-time surveillance in addition to general intelligence gathering. Before the development of devices such as radar, military forces relied on reconnaissance aircraft for visual observation and scouting of enemy movement.
The HolocaustThe Holocaust was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were carried out primarily through mass shootings and poison gas in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. The Nazis developed their ideology based on racism and pursuit of "living space" and seized power in early 1933.
Brest, BelarusBrest, formerly Brest-Litovsk and Brest-on-the-Bug, is a city in Belarus at the border with Poland opposite the Polish city of Terespol, where the Bug and Mukhavets rivers meet, making it a border town. It serves as the administrative center of Brest Region and Brest District, though it is administratively separated from the district. As of 2023, it has a population of 342,461. Brest is a historical site for many cultures, as it hosted important historical events, such as the Union of Brest and Treaty of Brest-Litovsk.
Phoney WarThe Phoney War (Drôle de guerre; Sitzkrieg) was an eight-month period at the start of World War II during which there was only one limited military land operation on the Western Front, when French troops invaded Germany's Saar district. Nazi Germany carried out the invasion of Poland on 1 September 1939. The Phoney period began with the declaration of war by the United Kingdom and France against Nazi Germany on 3 September 1939, after which little actual warfare occurred, and ended with the German invasion of France and the Low Countries on 10 May 1940.

The city is located in the Silesian Highlands, on the Kłodnica river (a tributary of the Oder). It lies approximately 25 km west from Katowice, the regional capital of the Silesian Voivodeship.

Second Polish RepublicThe Second Polish Republic, at the time officially known as the Republic of Poland, was a country in Central and Eastern Europe that existed between 7 October 1918 and 30 September 1939. The state was established in the final stage of World War I. The Second Republic ceased to exist in 1939, after Poland was invaded by Germany, the Soviet Union, and the Slovak Republic, marking the beginning of the European theatre of the Second World War. The Polish government-in-exile was established in Paris to replace the Second Republic in the war.
Strategic bombingStrategic bombing is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematically organized and executed attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability.
LublinLublin is the ninth-largest city in Poland and the second-largest city of historical Lesser Poland. It is the capital and the centre of Lublin Voivodeship with a population of 336,339 (December 2021). Lublin is the largest Polish city east of the Vistula River and is about to the southeast of Warsaw by road. One of the events that greatly contributed to the city's development was the Polish-Lithuanian Union of Krewo in 1385.
Pincer movementThe pincer movement, or double envelopment, is a military maneuver in which forces simultaneously attack both flanks (sides) of an enemy formation. This classic maneuver is important throughout the history of warfare. The pincer movement typically occurs when opposing forces advance towards the center of an army that responds by moving its outside forces to the enemy's flanks to surround it. At the same time, a second layer of pincers may attack the more distant flanks to keep reinforcements from the target units.
