Trench Foot: The frightening disease of WWI trenches
When soldiers climbed into the trenches of the Western Front between 1914 and 1918, they entered a world where the ground itself became an enemy.
Water pooled in every depression, mud clung to boots and uniforms, and the simplest act of standing guard transformed into an ordeal that could cost a man his feet.
Trench foot crept through battalions with such efficiency that British forces alone recorded over 20,000 cases by the winter of 1914-1915, with some divisions losing more men to the condition than to German machine guns.
What made this illness particularly hidden was the fact that it could have been prevented...
What was Trench Foot?
Trench foot developed when feet remained wet and cold for periods that typically lasted twelve hours or more.
The condition occurred when blood vessels in the feet constricted in response to cold and damp conditions, reducing circulation and depriving tissue of oxygen.
As a result, doctors in 1915 recognised that prolonged standing in water between 0 and 10 degrees Celsius created ideal conditions for the disease.
Unlike frostbite, which required freezing temperatures, trench foot attacked soldiers in conditions that seemed merely miserable rather than dangerous.
The doctors at the time initially struggled to classify the condition correctly, as some physicians mistook early cases for frostbite or simple inflammation.
By early 1915, British Army medical officer Captain Harold Wiltshire had documented the condition's unique characteristics and distinguished it from other cold-weather injuries.
His observations at casualty clearing stations near Ypres provided the first careful description of the disease progression.
As a result, military doctors soon learned that trench foot represented a form of peripheral vascular disease, where damaged blood vessels could no longer maintain adequate circulation to the extremities.
Soldiers typically spent four to six days in frontline trenches before rotation, and during winter months, water levels in such earthworks often reached knee height.
The combination of standing water, temperatures hovering just above freezing, and the impossibility of removing wet boots for days at a time created perfect conditions for the disease.
Men stationed at the Ypres Salient faced particularly severe risk since the low-lying Flanders terrain meant trenches filled rapidly with groundwater.
Indeed, at some sectors near Passchendaele, soldiers stood in water continuously from October through March.
What was it like to have Trench Foot?
Initially, feet felt cold and numb, sensations that soldiers often ignored as normal discomfort.
Within days, the skin turned red or blue as blood vessels struggled to maintain circulation and, as the condition worsened, feet swelled dramatically,sometimes doubling in size, making it impossible to wear boots.
Private Harry Patch of the Duke of Cornwall's Light Infantry recalled that his feet had become so swollen during the winter of 1917 that medics had to cut his boots away.
Pain accompanied the later stages with particular intensity. When circulation began returning to damaged tissue, soldiers experienced a burning sensation that many veterans described as worse than bullet wounds.
The skin developed a waxy appearance and blisters formed across the surface.
Subsequently, at severe stages, tissue began to die and turned black as gangrene set in.
In fact, Lieutenant Robert Graves wrote in his memoirs that men with advanced trench foot screamed throughout the night at casualty clearing stations.
Many soldiers lost feeling in their toes completely, a numbness that persisted for months or became permanent.
Others experienced hypersensitivity, where the lightest touch caused excruciating pain.
Second Lieutenant George Coppard described watching a fellow soldier weep uncontrollably when a nurse attempted to remove his socks at a field hospital near Arras during 1916.
A terrible problem
British forces evacuated approximately 74,000 men from the Western Front due to trench foot between 1914 and 1918.
The 48th Division reported during December 1914 that trench foot casualties exceeded battle casualties by a ratio of three to one.
As a result, battalion commanders found themselves unable to maintain fighting strength because of a preventable medical condition rather than because of German attacks.
The disease imposed enormous costs on military effectiveness, since each case removed a trained soldier from the line for weeks or months.
Severe cases required evacuation to hospitals throughout Britain, and this process consumed shipping space and medical resources needed for battle casualties.
At the Third Battle of Ypres during 1917, Field Marshal Douglas Haig's staff estimated that trench foot reduced available combat strength by approximately 15 per cent during the autumn offensive.
The condition struck experienced veterans and new recruits with equal frequency, depleting units of men who possessed valuable combat knowledge.
Strangely, military authorities initially treated trench foot as a disciplinary matter rather than a medical one.
During late 1914, the British Army issued orders stating that company commanders would be held responsible for cases occurring within their units.
This policy assumed that proper attention to foot care could prevent all cases. By early 1915, courts martial had punished several officers whose companies reported high incidence rates.
Captain J.C. Dunn was a medical officer with the Royal Welch Fusiliers and protested that such policies ignored the realities of trench warfare, where it was often impossible to keep feet dry.
How to prevent it
Prevention required careful attention to foot hygiene, which was difficult under battlefield conditions.
Medical officers recommended that soldiers remove their boots at least once daily, dry their feet thoroughly, and change into clean, dry socks.
Accordingly, the British Army began issuing three pairs of socks to each man, with instructions to carry the spare pairs inside their uniforms where body heat would keep them dry.
Whale oil became standard issue for troops occupying winter positions. Soldiers rubbed this grease onto their feet before they put on socks, and this created a water-resistant barrier that helped maintain skin integrity.
Trench construction methods evolved to address the problem, as engineers built wooden duckboards, which were slatted platforms that raised soldiers several inches above standing water.
By 1916, trenches at most sectors included such walkways as standard features.
Pumping stations removed water from deeper positions, and drainage sumps collected runoff.
The Canadian Corps earned particular recognition for trench maintenance, with units spending hours daily bailing water and repairing duckboards.
Their casualty rates from trench foot fell well below those of other formations operating within the same sectors.
Each morning, junior officers checked their men's feet for early warning signs,redness, swelling, or complaints of numbness.
Soldiers showing symptoms went to battalion aid stations immediately. This practice caught cases at early stages when treatment proved most effective.
The New Zealand Division implemented particularly very strict inspection rules during 1916, reducing their trench foot incidence by 70 per cent over six months.
Was there a treatment?
Medical officers treated trench foot through a careful process of rewarming damaged tissue.
When soldiers arrived at casualty clearing stations, doctors did not allow rapid warming.
Placing frozen or cold feet near fires or hot water bottles caused additional tissue damage as blood vessels could not adjust quickly enough to temperature changes.
Instead, medics gradually raised foot temperature to normal body heat over several hours, where they placed affected feet at room temperature first, then slowly increased warmth through careful application of blankets.
Elevation helped reduce the severe swelling that accompanied the condition.
Patients remained on bed rest with their feet raised above heart level for days or weeks.
Medical staff changed dressings frequently and monitored for signs of infection.
Blisters required careful management, which doctors provided when they drained them using sterile techniques but left the overlying skin intact to protect raw tissue beneath.
Any sign of gangrene demanded immediate attention, as bacterial infection could spread rapidly through damaged tissue.
Sadly, amputation became necessary at approximately three per cent of severe cases.
Surgeons at base hospitals throughout France performed thousands of operations between 1914 and 1918.
The procedure typically involved removing affected toes or, at extreme cases, the entire forefoot.
For example, Private Albert Andrews of the Middlesex Regiment lost four toes to gangrene during January 1916 after he had spent five days standing within flooded trenches at Loos.
Recovery from trench foot demanded patience. Mild cases required four to six weeks before soldiers could return to duty.
Severe cases meant months at hospital. Many men never returned to frontline service, instead receiving assignments to labour battalions or garrison duties.
Longterm impacts
Survivors of severe trench foot faced permanent disability, as circulation problems persisted for years after the war ended.
Veterans reported that their feet remained sensitive to cold temperatures, becoming painful during winter months.
Consequently, many men found they could no longer work at outdoor occupations since cold weather triggered symptoms.
George Winterbourne had been a Lancashire coal miner before the war and could not return to the pits after 1918 as the damp conditions underground caused his feet to swell painfully.
Also, nerve damage left permanent loss of feeling, with some veterans losing all feeling within their toes permanently, which increased their risk of injury since they could not detect cuts or pressure points.
Others experienced ongoing pain problems where damaged nerves sent constant pain signals to the brain.
The condition known as reflex sympathetic dystrophy affected hundreds of former soldiers, causing years of suffering that turned into a cycle of pain and disability.
Medical science during the 1920s offered little relief for such men.
The economic consequences lasted throughout veterans' lives, as men who had lost toes or portions of their feet found employment opportunities limited.
Physical labour became impossible for many, and the British government provided disability pensions, but payments rarely matched pre-war earnings.
Families struggled financially as breadwinners could no longer perform the work they had done before enlistment.
Medical knowledge gained from treating trench foot advanced understanding of peripheral vascular disease.
Doctors learned that prolonged exposure to cold and wet conditions damaged blood vessels in ways previously unrecognised, and this knowledge informed treatment of similar conditions within civilian life and provided the basis for modern approaches to cold-weather injuries.
The very careful records kept by military physicians between 1914 and 1918 continue to inform medical research into circulation disorders today.
