Post-War UNRRA (United Nations Relief and Rehabilitation Administration) Assistance to Livestock Restoration in Poland—Veterinary Challenges

Simple Summary

After World War II, Poland’s farming sector faced an acute shortage of working animals and dairy/beef cattle. Between 1945 and 1947, the United Nations Relief and Rehabilitation Administration (UNRRA) organised large-scale deliveries of horses and cattle to Polish ports from North America and several European countries. This article examines veterinary challenges connected with this programme: pre-shipment selection, shipboard clinical supervision under crowded and hot conditions, post-arrival quarantine and treatment in port clinics, and the associated mortality rates. Quantitative estimates cited in the paper are drawn from UNRRA mission reports and contemporary veterinary publications; the discussion also addresses how UNRRA supplies (medicines, equipment) and training activities supported post-war veterinary capacity.

Abstract

This article analyses post-World War II UNRRA (United Nations Relief and Rehabilitation Administration) activities that supported the restoration of livestock in Poland, with a focus on veterinary work associated with animal shipments. The study is based on archival UNRRA documentation (mission and programme reports) and contemporary veterinary publications describing clinical practice in Polish port clinics and on board livestock ships. It reconstructs major health risks during transoceanic transport (crowding, heat, poor ventilation); outlines veterinary procedures applied before loading, during the voyage, and after arrival; and summarises mortality and morbidity data reported for the period 1945–1946. By foregrounding veterinary practice within post-war humanitarian logistics, the paper contributes to a more detailed understanding of how animal health management shaped livestock rehabilitation efforts in Poland.

1. Introduction

The United Nations Relief and Rehabilitation Administration (UNRRA) was established in 1943 by 44 Allied countries (Szukała n.d.; Woodbridge 1950) to provide relief and to support reconstruction in territories affected by World War II (Woodbridge 1950; UNRRA 1947). Poland was among the major European beneficiaries of UNRRA assistance (Marks 1990; Łaptos 2015; Reinisch 2008; Sawicki 2017). Although UNRRA’s role in economic recovery has been discussed in the historiography, the veterinary dimension of its livestock programme—especially the practical challenges of maintaining animal health during long-distance transport and in post-arrival quarantine—remains comparatively underanalysed. This article addresses that gap by examining the organisation of veterinary supervision connected with UNRRA livestock shipments to Polish ports and by analysing clinical problems observed during transport and treatment outcomes in port clinics (Pępkowski 1947a; Czarnowski 1946; Staśkiewicz 1946; Seagoing Cowboys Blog 2021; Strieber 1947). The study asks (1) what health risks were documented during transport of horses and cattle, (2) how veterinary tasks were organised on the exporting and receiving sides, and (3) what morbidity/mortality figures reveal about the effectiveness and limits of these interventions in the immediate post-war context.

2. The Rise of UNRRA

The efforts of the Allied States to rebuild countries particularly affected by the war began even before the end of the Second World War. One of the most important tools of this aid was the UNRRA (United Nations Relief and Rehabilitation Administration), established in 1943 at a conference in Washington (Woodbridge 1950; UNRRA 1944; Columbia University Libraries n.d.). Its main objective was humanitarian aid and the devastated countries’ economic and social reconstruction (Woodbridge 1950; UNRRA 1947). The organisation covered many areas, including agriculture, public health, and veterinary medicine (UN Yearbook 1948; FAO 1948, 1949; UNRRA 1949). In Poland, UNRRA focused primarily on rebuilding the livestock population, crucial to the country’s food security. In addition to supplying the animals, UNRRA provided medicines and veterinary equipment and organised training for Polish veterinarians (Sawicki 2017; Łotysz 2018; UNRRA 1949). Plans for the reconstruction of Poland began to be drawn up as early as the summer of 1944 (Woodbridge 1950; UNRRA 1944). Initially, UNRRA held talks with the Polish Government in Exile in London, whose representatives attended the First Session of the UNRRA Council (Woodbridge 1950; Columbia University Libraries n.d.; FAO 1949). The situation changed when, in July 1944, the Soviet Union announced the administration handover of liberated Polish territories to the Polish Committee of National Liberation. UNRRA, trying to remain neutral towards the competing authorities in London and Lublin, found itself in a difficult position. Eventually, the situation was normalised after the US and UK recognised the Provisional Government of National Unity in July 1945 (Reinisch 2008, 2013; Woodbridge 1950). This early political uncertainty affected the timing of negotiations and staffing, and it also delayed the establishment of stable coordination channels needed for port logistics and veterinary arrangements described in Section 3 (Reinisch 2008, 2013; Sawicki 2017).

In March 1945, Mikhail A. Menshikov, Deputy Director General of the Area Office of UNRRA Headquarters, was appointed Chairman of the Provisional Delegation to Poland (UN Archives n.d.; UNARMS n.d.; Sawicki 2017). Its task was to negotiate an agreement with the Provisional Government, assess the country’s needs, and prepare the ground for the start of a permanent mission. Due to visa difficulties, the delegation did not arrive in Poland until July 1945. By October of the same year, the permanent mission staff began working in Warsaw (UN Archives n.d.; Sawicki 2017). One of the first problems faced was the shortage of qualified personnel. In time, however, these difficulties were overcome, and in January 1946, six regional UNRRA offices were established in Katowice, Kraków, Łódź, Poznań, Gdynia, and Warsaw. In September 1946, a seventh office was opened in Szczecin following the opening of the port there. At the peak of its activities in the second half of 1946, the UNRRA Mission in Poland had 162 international staff (Class I) and 260 locally recruited staff (Class II) (UN Archives n.d.; Sawicki 2017).

The main point of contact with the Polish government was the UNRRA Affairs Office, established at the Ministry of Shipping and Trade (Sawicki 2017). Other ministries also cooperated with it, setting up their coordination committees and drafting aid applications, which were sent to the Council of Ministers after verification by the relevant subcommittees. The first aid transports reached Poland in the summer of 1945 via the port of Constanta on the Black Sea and then overland via Romania, Hungary, and Czechoslovakia. In September of the same year, the ports of Gdynia and Gdansk were opened, allowing the more time-consuming land transport to be dispensed with (Sawicki 2017; UN Archives n.d.). The scale of UNRRA aid to Poland was enormous. The value of the supplies amounted to $477,927,000, and their gross weight exceeded 2,241,889 tonnes (UNRRA 1947; Sawicki 2017; UN Archives n.d.). This was the most significant aid to European countries in terms of value (Marks 1990; Reinisch 2008; UNRRA 1947). The organisational structure of the Polish UNRRA mission largely followed patterns used in other recipient countries, but in Poland, transport functions were organisationally separated from supply functions: the Department of Transport operated independently of the Department of Supply and reported directly to the Head of Mission, reflecting the centrality of port logistics and rail distribution in the Polish case (Sawicki 2017). The Department of Transport, headed by the Deputy Head of Mission, operated independently of the Department of Supply and was directly responsible to the Head of Mission. It managed water and rail transport supplies and supervised UNRRA port offices. It also coordinated the export of Polish raw materials, such as coal, to other UNRRA relief countries. The Department of Supply was responsible for distributing other supplies and implementing agricultural and industrial reconstruction programmes (Sawicki 2017). The UNRRA mission in Poland ended its activities on 30 June 1947 (Sawicki 2017; UN Archives n.d.).

3. The Challenges of Animal Transport

Initially, the organisers of this project thought they would be dealing mainly with logistical issues, including loading, transporting, and unloading animals at destination ports (UNRRA 1949; FAO 1948, 1949). The scale of the undertaking and the impact of intercontinental transport on animal health were not foreseen or were underestimated (Pępkowski 1947a; Czarnowski 1946; Strieber 1947). The need for veterinary care was assumed, but it was presumed that this would be needed within the limits of regular medical supervision. Transporting tens of thousands of animals across the ocean and several seas proved to be unprecedented and definitely affected their condition and health. Polish ports (Gdansk, Gdynia, and Szczecin) received almost 150,000 animals—primarily horses and cattle—of which up to 20% were reported as showing injuries, lesions, or signs of physical exhaustion upon arrival (Sawicki 2017; UNRRA/FAO n.d.). One ship usually housed 800 to 1000 animals, which occupied cramped and poorly ventilated quarters, with temperatures as high as 40 °C. It is not surprising that numerous deaths occurred; for instance, during transport to Gdansk on 3 July 1946, 19 horses did not survive (Pępkowski 1947b; Seagoing Cowboys Blog 2021; Strieber 1947). Dr. W. R. Strieber described the duties of the UNRRA veterinarian from the American side (Strieber 1947). After leaving UNRRA headquarters in Washington, veterinarians went to the transshipment ports from which livestock was shipped. The tasks of the veterinary service included the selection of animals, during which sick animals were separated from healthy ones. Sick specimens were sent to pens marked as hospital, surgery, lameness, sale, or disposal (Strieber 1947; Seagoing Cowboys Blog 2021). In the ‘hospital’, infectious diseases were treated, mainly goitre, influenza, pneumonia, and often secondary infections with reduced immunity (Strieber 1947; Czarnowski 1946). Medicines such as penicillin, intravenous and oral sulphonamides, and other symptomatic measures were used (Łotysz 2018; Czarnowski 1946). Some reports also mention trial use of newly introduced therapeutics to assess efficacy under shipboard and port-clinic conditions; however, the available summaries do not always specify protocols in detail (Czarnowski 1946; Strieber 1947; Łotysz 2018). In the surgery department, abscesses were worked out, wounds were treated, and fistulas of the glomus were opened. Purulent arthritis of lacrimal origin was also treated, and rectovaginal fistulas and other minor surgical cases were occasionally operated on. Diagnosis and treatment were carried out in the lame animal enclosure. Animals requiring long-term treatment were sent to the sales department, as it was impossible to continue treatment on-site (Strieber 1947).

Before loading, all healthy animals were directed to the wharf and underwent a final health check (Strieber 1947; Seagoing Cowboys Blog 2021). The day before loading, one of the two doctors accompanying the transport would review the medical equipment and medicines to ensure the kits were complete (Strieber 1947). Once approved, the equipment was transferred to the onboard pharmacy. UNRRA was also tasked with employing animal handling staff (stockmen) responsible for routine husbandry on board (stall management, cleaning, feeding, and watering) under veterinary supervision (Sawicki 2017; Strieber 1947). Loading usually lasted one day, after which the veterinarians started their duties already on board (Strieber 1947).

The working day during the cruise started at 8:30 in the morning. Two veterinarians would divide the animals into groups to monitor their health effectively. The rounds took place in the morning, after lunch, and after 8 p.m. The eye, nose, and mouth mucous membranes were checked for congestion, temperature was measured, and sick animals were diagnosed and treated (Strieber 1947; Seagoing Cowboys Blog 2021). The transport challenges are also evidenced in the memoirs of Dr. Harold Burton, an American veterinary graduate of the School of Veterinary Medicine, University of Pennsylvania, who provided care for transported animals (Seagoing Cowboys Blog 2021; Seagoing Cowboys Project n.d.). According to Burton, the job at sea was to keep the animals as healthy as possible, which, with the crowded conditions in the holds, was not easy. The rooms were very poorly lit, hot, and dusty, and horses and cattle always stood in manure (Seagoing Cowboys Blog 2021; Seagoing Cowboys Project n.d.). Burton said that veterinary care was an extremely demanding task. Performing intravenous injections in rough seas was not the easiest of tasks. Bites, kicks, bumps, and bruises were a daily occurrence for the veterinarians caring for the animals. In addition to treatment activities, the vets kept records and performed post-mortems on the dead horses so that UNRRA could use these reports to improve the conditions for transporting the next consignment of animals (Strieber 1947; Seagoing Cowboys Blog 2021; Seagoing Cowboys Project n.d.).

Shipboard documentation cited here focuses on clinical observations and necropsy findings. It rarely records the subsequent handling and disposal of carcasses after necropsy; this limitation is noted because carcass disposal was an important biosecurity issue in crowded shipboard conditions and merits dedicated archival study (e.g., ship logs and port sanitary records).

The unloading, examination (Figure 1), and selection of animals at the end of the journey, in turn, posed a considerable logistical challenge for the post-war Polish veterinary service (Sawicki 2017; Pępkowski 1947b; Staśkiewicz 1946). Approximately 50 horses and a similar number of cattle were estimated to remain from one transport for inpatient treatment. A total of 4688 out of 129,949 loaded horses died. Almost 17,658 horses passed through the clinics in Gdańsk, Gdynia, and Sopot (a complex of Polish port cities), and 2618 died. These figures illustrate the magnitude of the problems veterinarians face (Pępkowski 1947a; UNRRA/FAO n.d.). Upon arrival in Poland, the animals had to undergo a process of quarantine and adaptation to the new conditions (Sawicki 2017; Pępkowski 1947a; Staśkiewicz 1946).

The documents emphasise that American horses, although characterised by good trainability, were often in poor health after transport. Among the animals delivered by UNRRA, those with upper respiratory diseases predominated due to both the conditions of transport and a decline in the animals’ immunity. The documents also described cases of upper respiratory tract rhinitis and bacterial infections that required intensive treatment. One UNRRA report noted that among horses arriving from the USA, as many as 70% showed signs of respiratory disease within the first two weeks after arrival in Poland (Pępkowski 1947a; Czarnowski 1946; Staśkiewicz 1946; Wasielewski 2019). Veterinary clinics that received animals from UNRRA supplies used a variety of treatments. For respiratory diseases, sulphonamides, strychnine, and calcium salts were used. Antibiotics were also used in more severe cases, such as bronchopneumonia, although their availability was limited (Czarnowski 1946; Łotysz 2018). The papers emphasise that the best results were achieved by isolating sick animals and ensuring they were calm and fed correctly. One report describes that more than 80% of sick horses were rescued at the Animal Clinic in Gdansk due to intensive care (Czarnowski 1946; Staśkiewicz 1946; Wasielewski 2019).

shows the number of animals delivered to Poland as part of UNRRA aid and from Sweden (UNRRA/FAO n.d.; Sawicki 2017). In order to prevent the spread of infectious diseases, UNRRA also supported vaccination programmes, which were one of the key preventive measures. Horses suspected of having infectious diseases were immediately isolated to prevent epidemics (Sawicki 2017; UNRRA 1949; UNRRA/FAO n.d.).

Table 1 contextualises the scale and geography of the livestock operation: the overwhelming majority of animals arrived as part of UNRRA deliveries (141,645 of 150,357 total), and most consignments were handled by the ports of Gdańsk and Gdynia. This concentration helps explain why veterinary clinics in the Gdańsk–Gdynia–Sopot area carried a disproportionate clinical workload and why decisions about infrastructure expansion (e.g., the Wrzeszcz clinic) had immediate operational relevance.

Clinical descriptions from Polish port clinics underscore the typical post-transport syndrome. In Sopot, Dr. A. Czarnowski reported high fever (often 39–41 °C), tachycardia, congested or cyanotic mucous membranes, lacrimation, and bilateral nasal discharge that could become purulent or blood-tinged; cough was less frequent but appeared in severe cases (Czarnowski 1946). In a subset of cases with respiratory signs observed by 1 March 1946, outcomes were poor: 14 of 24 horses died with pneumonia, and post-mortem examination identified bronchial obstruction and multiple lung abscesses, with haemolytic streptococci frequently isolated bacteriologically (Czarnowski 1946). The report also documents therapeutic approaches used locally (including sulphonamide-based regimens and supportive injections), illustrating both the experimentation and constraints of immediate post-war clinical practice (Czarnowski 1946).

reproduces the mortality figures compiled by A. Pępkowski from contemporaneous UNRRA transport documentation for shipments to Poland between October 1945 and December 1946 (UNRRA/FAO n.d.). As can be seen from these data, the majority of horses came from the USA (UNRRA/FAO n.d.; Sawicki 2017). Horses from nearby European sources (e.g., Sweden, Ireland, and Iceland) arrived after shorter voyages, which likely reduced transport-associated stress and post-arrival morbidity compared with transatlantic consignments (Pępkowski 1947a; UNRRA/FAO n.d.). Experience gained during the first shipments in 1945 appears to have contributed to lower mortality rates in 1946 despite far larger volumes, alongside improvements in the organisation and infrastructure of the Polish veterinary service (Pępkowski 1947b; UNRRA/FAO n.d.).

4. Discussion

UNRRA livestock shipments should be understood not only as a quantitative contribution to herd rebuilding, but also as a test of post-war humanitarian logistics in which animal health management became a limiting factor. For clarity, the discussion is organised into three short subsections: (i) veterinary and animal health challenges, (ii) operational/logistical implications, and (iii) institutional impact.

4.1. Veterinary and Animal Health Challenges

UNRRA documentation and contemporary veterinary publications indicate that the dominant veterinary problems were transport-associated respiratory disease, exhaustion, and trauma in both horses and cattle (Pępkowski 1947a; Czarnowski 1946; Staśkiewicz 1946; Seagoing Cowboys Blog 2021; Strieber 1947). Quantitative indicators of the transport burden include reports that up to 20% of animals arrived with injuries, lesions, or signs of marked physical exhaustion (Sawicki 2017; UNRRA/FAO n.d.), as well as shipboard mortality among horses during 1945–1946 of 4,688 deaths out of 129,949 loaded animals (3.6% overall; Table 2) (UNRRA/FAO n.d.). Mortality was substantially higher in 1945 (7.3%) than in 1946 (3.5%), and losses were concentrated in transatlantic consignments from the USA (4.8% across the period), while the much smaller Danish shipments reported very low mortality (0.1%; Table 2) (UNRRA/FAO n.d.).

Port-clinic reports suggest that morbidity after arrival was extensive and often dominated by upper respiratory disease. One UNRRA-related report noted that among horses arriving from the USA, up to 70% showed respiratory signs within the first two weeks after arrival in Poland (Pępkowski 1947b; Czarnowski 1946; Staśkiewicz 1946; Wasielewski 2019). Another report from the Animal Clinic in Gdańsk described the recovery of more than 80% of sick horses under intensive isolation and supportive care (Czarnowski 1946; Staśkiewicz 1946; Wasielewski 2019). These figures underscore that the effective contribution of imported livestock depended not only on survival during the voyage but also on successful post-arrival quarantine and treatment.

Qualitative evidence complements these numerical summaries by describing the mechanisms through which transport conditions translated into disease and trauma. Shipboard accounts emphasise crowding, high temperatures, poor ventilation, dust, and continuous exposure to manure, as well as the practical difficulty of performing examinations and injections at sea in rough conditions (Seagoing Cowboys Blog 2021; Seagoing Cowboys Project n.d.). Together, quantitative and qualitative sources suggest that veterinary intervention had to combine pharmaceuticals (where available) with non-pharmaceutical measures such as isolation, improved shelter, adequate feeding and watering, and stall hygiene (Czarnowski 1946; Łotysz 2018).

4.2. Operational and Logistical Implications

Operationally, the programme created recurrent bottlenecks in a small number of receiving ports. The concentration of deliveries in the Gdańsk–Gdynia–Sopot complex meant that quarantine capacity, clinic throughput, staffing, and drug supplies had to scale rapidly (Pępkowski 1947b; Czarnowski 1946; Staśkiewicz 1946; Wasielewski 2019). In this setting, veterinary work acted as an enabling constraint for humanitarian logistics: delays in triage, isolation, or basic husbandry could amplify clinical burdens and reduce the number of animals that could be redistributed quickly to farms.

To clarify the phrase “where figures allow”, the evidence base contains both quantitative and qualitative material. Quantitative data include (a) shipboard mortality rates by year and origin (Table 2) (UNRRA/FAO n.d.), (b) reported post-arrival morbidity proportions (e.g., up to 70% respiratory signs within two weeks) (Pępkowski 1947a; Czarnowski 1946; Staśkiewicz 1946; Wasielewski 2019), and (c) reported clinic outcomes (e.g., more than 80% recovery in the Gdańsk clinic) (Czarnowski 1946; Staśkiewicz 1946; Wasielewski 2019). Qualitative evidence includes descriptive accounts of shipboard conditions and clinical narratives that explain how crowding, heat, ventilation, and husbandry constraints shaped disease progression and treatment priorities (Seagoing Cowboys Blog 2021; Seagoing Cowboys Project n.d.).

The pattern over time also suggests organisational learning. Despite far larger volumes in 1946, the compiled shipboard mortality rate for loaded horses decreased from 7.3% in 1945 to 3.5% in 1946 (Table 2) (UNRRA/FAO n.d.), consistent with incremental improvements in selection, shipboard routines, and reception infrastructure across successive transports (Pępkowski 1947a; UNRRA/FAO n.d.).

4.3. Institutional Impact and Capacity Building

Beyond immediate clinical outcomes, UNRRA assistance contributed to post-war veterinary capacity building. Deliveries of equipment and medicines, together with reported training activities, strengthened the material base of Polish veterinary services and supported the standardisation of quarantine administration and mass-transport surveillance routines in port settings (Sawicki 2017; Łotysz 2018; Jones and Koolmees 2022).

At the same time, the termination of UNRRA operations in Poland in 1947 had practical implications: it curtailed a supply channel for medicines and equipment and interrupted the accumulation of operational experience that had begun to reduce losses across successive shipments (Reinisch 2008, 2013; Sawicki 2017; Łaptos 2018). Historically, the case illustrates how veterinary modernisation in the immediate post-war period depended not only on national institutions but also on the continuity of international logistical and organisational support.

5. Conclusions

Archival and contemporary veterinary sources indicate that UNRRA livestock deliveries to Poland were accompanied by substantial animal health challenges that shaped how effectively imported horses and cattle could contribute to post-war recovery. The main problems documented were transport-associated respiratory disease, exhaustion, and injuries, addressed through selection, repeated clinical rounds, quarantine and isolation, and supportive treatment—while pharmaceuticals played an important but context-limited role.

The available record is uneven in its operational detail. In addition to incomplete reporting on carcass disposal after necropsy, documentation is not consistently specific about feeding and watering routines (quantities and timing), stall hygiene and bedding management, ventilation measures, staffing ratios on ships and in port clinics, or the precise protocols behind some reported therapeutic trials. These gaps limit the granularity with which the full biosecurity and husbandry chain can be reconstructed.

Further work could integrate ship logs, port sanitary/veterinary documentation, and Polish administrative records to clarify the operational chain from loading through quarantine and redistribution. A comparative perspective—contrasting the Polish port experience with other UNRRA recipient countries or parallel post-war livestock rehabilitation programmes—could also help distinguish which challenges were specific to Polish infrastructure and which were structural to long-distance livestock relief.
