Italy in World War II gets a bad reputation as a nation that never accomplished anything, and was ultimately irrelevant to the outcome of the war. But when the Allies finally decided to invade Italy in 1943, they quickly became stalemated by a series of expert-crafted defensive lines created by the German general Albert Kesselring. Join us as we explore exactly how the invasion that was predicted to last only a few months turned into a grueling ordeal that lasted all the way up until the Axis surrender, and cost the Allies over 300,000 casualties.

With winter rapidly closing in, the Allies had little time to prepare for their assaults on
Kesselring's masterpiece. An innovator in both military tactics and apparently chess, the gambit
we've named after the German General includes distracting your opponent and quickly switching
out all of your pawns for castles. On the 1st of December, the first probing attacks began in the
West, made against a large bulge in the German defenses known as the Bernhardt Line. Conditions
were terrible, with freezing temperatures and heavy snowfall making for an agonizing trek for
the soldiers as they struggled their way through hostile terrain. After several weeks of intermittent
engagements, the Allies were only able to wrestle a number of small villages away from enemy control.
In the end, it was the Germans who decided to withdraw, falling back to the more tenable Gustav
Line in early January of 1944. While the 5th Army was busy dying in the snow, the 8th Army also found
well, dying in the snow. The 8th had attacked the Gustav Line on the 4th of December and made
significant headway, but then the Germans made a strategic withdrawal through a deep gully,
which funneled the Commonwealth forces into a carefully prepared killing ground. Any unit
entering the gully was brutally mauled and Allied progress was completely stalled until German forces
withdrew to a new position on the 20th. The next set of battles for the Gustav Line took place at
towns of Ortona and Orsonia. The former proved an absolute nightmare for the Canadian units
assigned to capture it, as they were forced to engage in some of the bloodiest street fighting
on the Western Front. The German parachute battalion defending the town had dug in deep,
and had to be fought from building to building in a protracted struggle that resulted in roughly
4,500 casualties altogether, decimating both the 1st Canadian Division as well as the civilian
population. Orsonia, meanwhile, resisted every attack, holding out until a massive blizzard
struck the Adriatic coastline and forced the British to halt their offensive. But even this
could not end the bloodshed for long, and on January 14th, the two Allied armies launched
yet another series of attacks on the line, starting the notorious battle for Monte Cassino.

three days of pointless slaughter. Two more attacks failed due to either terrain or a lack
of armored support, and a fourth ended with minor gains that were promptly abandoned due to the lack
of supplies. After these repeated failures, the Allies authorized Operation Avenger, which fixated
on the Monte Cassino Abbey as the linchpin of German defenses in the area. On February 15th,
a huge bomber raid reduced the abbey to a smoldering pile of rubble. Unfortunately, the raid
was badly coordinated, and was not followed up by a ground assault, so in the end, little was
accomplished. While this was ongoing, the Allies had also conducted a naval landing near the city
of Anzio to outflank the Gustav Line. But after landing relatively unopposed, General John P.
Lucas made the inexplicable decision to dig in and fortify his position rather than push inland.
Kesselring promptly wheeled his reserves about and smashed into the beachhead, beginning a long
battle of attrition that would last until May. Meanwhile, the third battle for Cassino began on
March 15th, with a creeping barrage that disordered the German line. But this ray of hope was quickly
snuffed out by heavy rains, giving the Germans time to prepare. However, by now it was clear that
the Axis was losing the battle of attrition, and the final breakthrough came on May 11th, when both
the Eighth and Fifth Armies attacked at once, aided by the French Expeditionary Corps and even
some Polish forces. This last tremendous push finally fractured the Gustav Line, which held
for nearly six months. But although the main line of Axis defenses had been breached, there was still
much to be done, and the push north continued. A breakout was also staged at Anzio with the help of
an artillery bombardment and close air support. In danger of becoming encircled, Kesselring received
orders to fall back. But right at the pivotal moment, General Mark Clark decided to ignore
orders to pursue the German army and instead drove towards Rome. Unable to believe his luck,
a delighted Kesselring quickly pulled back to yet another set of defensive works, codenamed
the Gothic Line. After so much blood had been shed, the actual capture of Rome was something
of an anticlimax. With German attention turning towards the inevitable invasion of France, the
city had all but been abandoned. After a few brief skirmishes, Rome was liberated on June 4th,
just two days prior to the landings in Normandy. Getting there had required 600,000 Allied troops,
over 100,000 of which had become casualties since the day they first landed in Italy.
But despite their grievous losses, there was little time to rest and recuperate. Kesselring
had proven a genius at defensive warfare, and leaving him to his own devices would undoubtedly
prove disastrous. Thus, British and American armies raced up the coast, only to be checked
yet again at the improvised Trasimene Line, encountered on June 20th. Stalled for another
week, the Germans had ample time to move the bulk of its army to the Abenine Mountains.
Infuriated but impotent, the Allies could do nothing but resign themselves to yet another
long, grinding siege. On August 25th, the Allies launched Operation Olive, aimed at breaching the
Gothic Line and finally ending the seemingly eternal battle for Italy. The Eighth Army was
to attack German positions along the Adriatic coast, and when Kesselring had committed his
reserves to that area, Mark Clark's Fifth Army would strike at the weakened center,
breaking through to Bologna. Initial progress was good, but Kesselring continued to pull his
old tricks and refused to be lured into fighting on unequal terms. By the end of September,
the Allies had clambered their way over the peaks of the Abenine Mountains, having suffered 14,000
casualties. Then, autumn rains stalled further attacks, grounding air support and turning vital
supply routes into impassable quagmires. At this point, the remainder of 1944 would be spent in a
deadlock, with a single Axis counterattack in December managing to briefly reoccupy a section
of the Gothic Line. Although Kesselring had done a spectacular job in Italy, his position was about
to change drastically. He was severely injured in a car crash in October, and upon his recovery,
found himself replacing Field Marshal Gerdt von Rundstedt as commander of the entire Western Front
on March 10th. Even he could do nothing but watch the final collapse of the Third Reich,
as Allied troops were already pouring into Germany itself. In spring of 1945, the Allies launched
their final offensive in Italy, Operation Grapeshot. During the months-long stalemate,
the 5th and 8th Armies had been reinforced by a diverse collection of units from various nations,
including several thousand British-trained Italian volunteers and even a division from
the Brazilian Expeditionary Force. The attack began on April 6th with a long artillery bombardment,
then attacks all along the line by Commonwealth troops. Without any reserves left, the Germans
could no longer do anything but desperately try to hold the line. However, the situation was
hopeless. By the 20th of April, the two Allied armies had broken into the Po Valley, and only
five days later, Mussolini was dragged out of hiding by Italian partisans and summarily executed.
With no reason left to fight, Kesselring's replacement opened up negotiations with the Allies
and signed a surrender order on May 2nd, just a few days before the official end of the war in Europe.
After so many gambits and clever plays, the chessboard of Italy had been cleared.
The final handshake between players would occur at last, a year and a half after the start of
their unexpected rematch. In many ways, the Italian campaign showcased both the best
and worst moments from the Second World War. The idea to divert forces from the Eastern Front was
sound, but internal division quickly turned the campaign into an unfocused mess. Supplies were
diverted to other operations, and arguments among Allied generals led to missed opportunities and
long delays. Kesselring also demonstrated exactly how deadly the Wehrmacht could be on the defense,
holding out for over a year against a much greater force, which by that point possessed
total air superiority. But the battles in Italy kept hundreds of thousands of German soldiers
occupied at a time when manpower was critically low, and the experience gained from the amphibious
landings at Salerno proved invaluable to the planners of D-Day. Still, historians remain
divided on the campaign, with many arguing that it was an outright strategic failure. But others see
it as part of a bigger picture, a necessary, even vital component to the fall of the Axis powers
and the liberation of Europe.
