11 July 1943: how to map Bloody Sunday without turning a symbol into a false total

01

A date is a lens, not the whole event

11 July became the symbol because the attacks were simultaneous, extensive and deliberately timed.

The phrase Bloody Sunday is useful when it identifies a concentrated wave of violence. It becomes misleading when it is treated as if the campaign began at dawn on 11 July and ended at midnight. Mass killings of Polish civilians in Volhynia had already escalated during the preceding months, and further attacks followed on 12 July and throughout the summer. A responsible map therefore places the date inside a longer sequence rather than presenting it as an isolated eruption. ^1,4,9

The same caution applies in the other direction. Calling 11 July only a symbol must not dissolve the concrete events into an abstract Polish-Ukrainian conflict. Contemporary testimonies, later investigations and locality studies describe attacks on homes, churches, colonies and estates across several counties. The people represented by the points were not symbols. They were residents caught in specific places, often without warning, and their individual stories require event-level documentation. ^3,7

02

The campaign was already underway

Parośla, Lipniki and Janowa Dolina show why 11 July cannot be used as the starting date.

IPN chronologies identify the massacre at Parośla I on 9 February 1943 as the first large-scale killing of a Polish settlement by a unit operating under the UPA name. Further major attacks included Lipniki in the night of 26 to 27 March and Janowa Dolina on 23 April. The exact victim estimates remain source-dependent, but the sequence is not in doubt: by July, violence against Polish rural communities had moved beyond isolated murders and had become a sustained regional campaign. ^4,9

This earlier chronology also changes how warnings and flight are interpreted. Some communities had heard of killings elsewhere, yet information travelled unevenly and was mixed with rumours, reassurances and deliberate deception. Residents could not know whether their own village would be attacked, whether an agreement would be respected, or whether leaving home would expose them on the road. The later scale of 11 July should not be projected backward as knowledge that every victim possessed beforehand. ^1,5

03

Organisation, command and local execution

Responsibility must be reconstructed at several levels instead of reduced to one name.

Research by Grzegorz Motyka, Timothy Snyder and Jared McBride treats the anti-Polish campaign in Volhynia as organised violence led by the OUN-B underground and UPA structures, not as a spontaneous peasant revolt. The regional command associated with Dmytro Klyachkivsky, known as Klym Savur, is central to the reconstruction. At the same time, a regional decision does not identify the unit, commander and chain of actions behind every village. Those links require local orders, testimonies, post-war interrogations and comparison of routes. ^8,9,7

The distinction is especially important for Roman Shukhevych. He was a senior OUN-B leader in 1943, but the unified supreme command of the UPA was created later in the year and he became commander-in-chief in November. This does not remove organisational or political questions from his biography, but it prevents the map from assigning him a formal July command title that he did not yet hold. Dossiers must preserve chronology even when later public memory prefers a single, simplified hierarchy. ^10,11,17

04

Why credible sources give different counts

Ninety-nine, more than one hundred, and 97 plus 13 are not necessarily contradictory statements.

An IPN educational calendar states that 99 Polish localities were attacked on 11 July and 65 on 12 July. Other IPN publications write of more than one hundred localities. A detailed reconstruction by Ewa Siemaszko, reproduced by IPN, separates 97 villages and colonies from 13 estates. The resulting figures count different categories: a broad locality, a village or colony, an estate, a church site, or a source entry. None should be silently substituted for another. ^2,3,1

The atlas adds another layer of complexity. One historical settlement may have several cards because different groups of victims, dates or sources were recorded separately. Conversely, one card may cover a date range such as 11 to 12 July or several parts of a dispersed colony. For that reason the interface should show record count and reconciled locality count separately. The first measures documentation units; the second is an editorial geographic approximation. Neither is a direct victim total. ¹⁶

05

The geography of the coordinated wave

The strongest concentration lay in the Włodzimierz and Horochów counties, with attacks also recorded elsewhere.

IPN reconstructions place the main 11 and 12 July concentration in the Włodzimierz and Horochów counties, with cases in the Kowel area as well. This was not a random scatter. The clustering reflects operational movement, road and forest access, parish networks and the distribution of Polish villages, colonies and estates. Mapping the points together makes coordination visible, but it can also exaggerate precision when the historical source identifies only an approximate settlement centre. ^2,3

Present-day borders create a second distortion. The attacked communities belonged to the Volhynian Voivodeship of the Second Polish Republic under German occupation; today most sites lie in Ukraine and some historical names no longer identify living settlements. The atlas therefore stores historical region, present-day country and coordinate confidence separately. A modern national border is useful for navigation, but it must not be mistaken for the wartime administrative or social landscape. ^16,9

06

Church attacks and the logic of Sunday

Services concentrated residents, but the violence of the day extended far beyond church buildings.

IPN lists attacks during services in Chrynów, Poryck, Zabłoćce, Kisielin and the chapel in Krymno, as well as killings near the church in Koniuchy. Plans also concerned Zaturce and the chapel in Kalinówka, but the intended scenarios were not completed in the same way. These cases explain why Sunday mattered operationally: residents from a parish and surrounding settlements could be found together at a predictable time. ^3,1

The church sites became powerful places of memory because ruins, photographs and survivor accounts give the violence a visible centre. Kisielin is a clear example: some people were killed around the church complex, while a group barricaded itself in the presbytery and resisted for hours. Yet an atlas dominated by famous churches would misrepresent the day. Most attacked residents were killed in homes, farm buildings, fields, roads, villages, colonies and estates that left fewer recognisable monuments. ^6,5,3

07

The violence was organised, but participation was not socially uniform

Separating organisers, armed units, local auxiliaries and coerced participants prevents collective guilt.

McBride’s archival microhistory of the Liuboml area demonstrates that organised ethnic cleansing could mobilise a mixed body of perpetrators. It included nationalist cadres and armed formations, but also local auxiliaries recruited through authority, pressure, fear, material interest and existing conflict. The finding does not make the campaign spontaneous. It explains how an organised decision could be implemented across many rural communities by people with different degrees of initiative and commitment. ⁷

This differentiation is also an ethical rule for public presentation. The perpetrators were not the Ukrainian population as a whole. Some Ukrainians warned neighbours, hid people, intervened or refused participation, while others took part in violence or looting. A map that labels every surrounding village as complicit would replace historical investigation with ethnic accusation. Responsibility must remain attached to documented organisations, units and persons, with rescue and refusal recorded where evidence exists. ^7,1,18

08

Escape, resistance and intervention

The map contains massacres, failed attacks, defended sites and places where warning changed the outcome.

Not every planned or attempted attack produced the same outcome. IPN accounts note that railway workers at Zwiniacze repelled an assault because they had weapons, residents of Witoldówka escaped before the attackers arrived, and intervention by Ukrainian village heads helped prevent killings in the Bielin and Kalinówka area. In Kisielin, a group of parishioners survived after barricading themselves and resisting. These cases do not reduce the scale of the campaign, but they reveal the conditions that could alter survival. ^1,6

Survivor testimony is essential but must be handled with care. A child’s memory can preserve sounds, movements, family relationships and the sudden collapse of ordinary life that an administrative list cannot convey. It may not resolve the identity of every attacker or the exact sequence across several settlements. The strongest reconstruction combines testimony with parish records, underground reports, unit histories, exhumation evidence and comparison between independent accounts. ^5,6

09

Victim totals: evidence, ranges and false precision

A sourced estimate can be informative without becoming a final census.

One detailed IPN publication reports at least 3,102 Polish victims on 11 July and at least 2,020 on 12 July, explicitly describing the figures as incomplete. These estimates are valuable because they show the magnitude of the two-day wave. They should not be converted into an exact final balance. Records may contain minimums, ranges, unnamed family groups, duplicated persons, residents killed elsewhere, or people whose fate was clarified only after publication. ^3,1

For this reason the atlas does not sum every victim field attached to 11 July. A sum produced by software would look authoritative while inheriting all duplication and uncertainty in the inputs. Instead, the dossier reports published external estimates with attribution, displays locality-level ranges where available and marks confidence. The correct question is not simply what number the database produces, but what exactly was counted, by whom, from which sources, and with what unresolved cases. ^16,3

10

11 July did not end at midnight

The coordinated violence continued on 12 July and through the following weeks.

IPN sources describe a second coordinated wave on 12 July. Here again counts vary: the educational calendar gives 65 localities, while another reconstruction gives 67 localities and two estates. The variation reinforces the methodological point rather than weakening the evidence for coordination. A date filter that selects only 1943-07-11 risks omitting records dated 11 to 12 July and presenting the second day as an unrelated event. ^2,1

The campaign also continued after the two symbolic days, and later spread with different intensity and organisation into Eastern Galicia. Treating Bloody Sunday as a complete name for all anti-Polish violence can therefore obscure regional phases, changes in command and the chronology of particular units. The dossier uses 11 July as an entry point, then links readers to the broader crime-site layer and to separate investigations of destroyed settlements, command responsibility and later exhumations. ^9,11,4

11

Genocide, ethnic cleansing and conflict

The terms describe different legal, scholarly and memorial frameworks and should be attributed.

Polish state institutions and legislation use the term genocide for the crimes committed by OUN, UPA and related nationalist formations against Poles. A substantial part of international scholarship uses ethnic cleansing, sometimes while discussing whether particular phases or the wider campaign also satisfy definitions of genocide. Ukrainian public discourse has often used tragedy, conflict or Polish-Ukrainian war. These labels are not interchangeable, and the differences should not be hidden behind a supposedly neutral vocabulary. ^14,9,7,12

Attribution allows the dossier to be both clear and honest. It can state that the Polish legislature recognises genocide, that named scholars analyse an organised ethnic-cleansing campaign, and that memory politics in Ukraine often frames the events differently. Presenting the divergence is not the same as declaring every interpretation equally supported. Event-level evidence of systematic attacks on Polish civilians remains the foundation; terminology is then explained in relation to law, intent, scale and scholarly argument. ^12,13,8

12

From anniversary to state holiday

Public commemoration has given 11 July a meaning that extends beyond the historical two-day operation.

In 2016 the Polish Sejm established 11 July as a national day of remembrance by resolution. In 2025 Parliament adopted a statute making it the National Day of Remembrance of Poles, Victims of Genocide committed by OUN and UPA in the eastern territories of the Second Polish Republic, and defining it as a state holiday. The law entered into force on 5 July 2025. The legal name broadens commemoration beyond the victims killed on the single date. ^15,14

The date therefore performs two functions. Historically, it identifies a peak of coordinated violence in Volhynia. Publicly, it serves as a national memorial day for a broader group of victims across several regions and years. Confusing the functions creates errors: the total number commemorated by the holiday is not the victim count for 11 July, while the map of 11 July cannot stand in for every crime covered by the legal remembrance. The portal keeps the anniversary dossier and the full crime layer connected but distinct. ^14,15,16

13

The editorial test for every point

A professional record must make the route from claim to source visible.

For every 11 July point the portal should record the historical name, present-day location, date precision, type of settlement, victim estimate with its source, perpetrator description, coordinate confidence and publication status. If several cards concern the same settlement, the relationship must be explicit. If a source gives only a date range, the interface must not silently convert it into a single day. If a coordinate is approximate, the map must say so. ¹⁶

Historical names require the same discipline. A colony may have been administratively linked to a larger village while functioning as a separate Polish community; an estate may appear under the name of a nearby settlement; post-war renaming can create several modern candidates. The editorial record should retain the source wording, list verified aliases and explain why the coordinate was chosen. Search convenience must not erase the settlement form that shaped who lived there, how the attack was organised and why different publications produce different locality counts. ^16,3

The dossier is complete only when a reader can move in both directions. From the overview, the reader should reach individual locality records and their sources. From a locality card, the reader should return to the broader chronology without assuming that one village represents the whole campaign. This two-way structure turns the map from an illustration into a research interface. It also makes corrections possible when a new source changes a name, coordinate, date or victim range. ^16,3

Timeline

1. September 1939: The wartime borderland is dismantled

   German and Soviet occupation destroyed institutions of the Second Polish Republic and transformed relations, security and power in Volhynia. ⁹

2. June 1941: German occupation of Volhynia

   The German invasion of the Soviet Union brought Volhynia under Nazi occupation and created a new environment for underground and auxiliary formations. ^9,11

3. Autumn 1942: OUN-B armed formations expand

   OUN-B began organising armed units in Volhynia that later became the dominant UPA structure in the region. ¹⁰

4. 9 February 1943: Parośla I

   IPN chronologies identify the massacre as the first large-scale killing of a Polish settlement by a unit operating under the UPA name. ⁴

5. March 1943: Police desertions strengthen the UPA

   Thousands of Ukrainian auxiliary policemen left German service, providing weapons and trained personnel to the expanding insurgent forces. ^11,10

6. 26-27 March 1943: Lipniki

   A major attack on the Polish settlement confirmed that mass violence was escalating before July. ⁴

7. 23 April 1943: Janowa Dolina

   The destruction of the workers' settlement became another major stage in the widening campaign. ⁴

8. 8 July 1943: The Rumel mission ends in murder

   Polish underground representatives Zygmunt Rumel and Ryszard Markiewicz disappeared during a mission to negotiate with OUN-B representatives and were killed. ¹

9. 11 July 1943: Coordinated peak of attacks

   UPA units and associated local forces attacked Polish villages, colonies, estates and church communities across a concentrated area of Volhynia. ^2,3,1

10. 11 July 1943: Attacks during Sunday services

    Among the attacked church sites were Poryck, Chrynów, Zabłoćce, Kisielin and Krymno. ^3,6

11. 12 July 1943: The second coordinated wave

    Attacks continued across dozens of localities; published reconstructions differ on whether the count is 65 or 67 localities plus two estates. ^2,1

12. July-August 1943: Violence continues beyond the symbolic date

    Further attacks, flight and the destruction of settlements continued through the summer. ^9,4

13. November 1943: Shukhevych becomes UPA commander-in-chief

    The later appointment is essential when separating July's regional command structure from the unified UPA hierarchy created later in 1943. ¹⁰

14. 1944: The anti-Polish campaign expands in Eastern Galicia

    The chronology and command structures differed from the Volhynian peak and require separate event-level analysis. ^9,11

15. 22 July 2016: Sejm resolution establishes the remembrance day

    The Polish Sejm designated 11 July as a national day of remembrance and called for historical truth and reconciliation. ¹⁵

16. 5 July 2025: The remembrance day becomes a state holiday

    The 2025 statute entered into force, giving the official commemoration a broader legal name covering victims beyond the single anniversary date. ¹⁴
