  All this took time. The Panzer III went through no fewer than four type designations before the Model E was considered sufficiently refined to manufacture in some numbers. Even then the first general-production version of the tank was one letter later. The Mark F went into production in September 1939—just too late for the Polish campaign.

  The same could not be said, albeit just barely, for its designated partner. The Panzer IV would remain in production throughout the war. The most numerous and the most versatile tank the Wehrmacht developed, it is also usually considered one of the world’s classic armored vehicles, a strong contender for Top Ten status in any comparative listing. Its origins were unpretentious. The Weapons Office wanted armaments firms to gain experience designing and producing heavy tanks. Lutz and Guderian had from early days seen the need for a support tank. The result was a project for a “battalion commander’s vehicle” of 24 tons—the bridge weight limit—mounting a 75mm gun, which was really a howitzer, only 24 calibers long. Dubbed by its crews as the “cigar butt” and other, cruder names involving length, its high-explosive and smoke shells were intended to provide for close support—not only for tanks but for their accompanying infantry. In the war’s early years, however, a three-inch shell exploding on or near a tank could do significant damage—not least to crew morale. The Panzer IV would acquire from its early days an enduring reputation as a formidable opponent.

  The Panzer IV suffered from an embryonic armament industry’s lack of experience producing even moderately large tanks, and from an increasingly overstrained manufacturing capacity. Only about 200 were on inventory by September 1, 1939. That was enough, however, to begin allocating a company to each battalion, and to test the three-to-one combination initially proposed by Lutz and Guderian. The design withstood prototype testing admirably. The Panzer IV’s suspension matched its eventual 20-ton weight, and was so reliable it became standard for all the later versions. Its superstructure was proportioned generously enough to allow for up-gunning. Its turret was electrically powered, improving exponentially the chances of getting off the first shot so often decisive in mobile war. Add standard frontal armor of up to 50mm, with 20mm on the sides and rear, plus a reliable Maybach engine giving a top speed of 20 miles per hour and a 100-mile range, and the Panzer IV was a crew’s delight when it began entering unit service in 1938.

  The panzer force was taking delivery of a wide variety of other armored vehicles as well. Among the most significant, and probably the most overlooked, was the armored command vehicle. Lutz’s insistence that commanders of mobile forces must command from the front implied a need for an appropriate mount. The early tanks were too small and cramped to allow for the additional, still-bulky signal apparatus, and for an extra man to operate it. In 1938 the first versions of a converted Panzer I made their appearance. The turret was replaced by a fixed superstructure, a signaler was added, and the interior reconfigured to accommodate a table, map boards, and most important, two radios: one to communicate with the unit’s tanks and one to keep in touch with higher headquarters. They were cramped and inconvenient, but the equipment worked—and they looked enough like ordinary tanks not to offer obvious targets. Around 200 were available for the Polish campaign, where they proved key links in the communications network that gave the Wehrmacht its nervous system.

  In the German concept of mobile war, wheels were only marginally less important than tracks. That said, the first example was unimpressive: an open-topped scout car built on a civilian truck chassis, with a two-man crew, 8mm of armor, and a light machine gun. Entering service with the cavalry, by 1939 it had devolved to the infantry’s reconnaissance battalions as one step above bicycles. Next step was a two-step: the development and introduction of the Leichter Panzerspähwagen Sonderkraftfahrzeug (SdKfz) 221/222—a Teutonic mouthful that translates as Armored Reconnaissance Car Special Purpose Motor Vehicle 221/222, and thankfully shortens simply to Armored Car 221/222. The latter, definitive version began joining reconnaissance battalions during 1938. A four-wheeled, five-ton vehicle, with a 20mm cannon or a light antitank rifle in an open-topped turret and a two-man crew, it could do 50 miles per hour on roads, half that across country, thanks to its four-wheel drive and a relatively powerful engine. The 222 was popular in service and easy enough to manufacture that a number were exported to Nationalist China, where it was also well liked.

  The 222 is best understood as an upscale version of the Daimler scout car coming into British service about the same time. It could gather information but was ill-suited to fight for it. Apart from that, the German army had enough of a tradition of heavy wheeled vehicles to encourage the simultaneous development of the SdKfz Heavy Armored Car 231—Six-Wheeled. The 231 could trace its origins to a civilian-developed vehicle whose initial version was too heavy and too expensive. Rejiggered into a six-wheel design built, initially, around a Daimler-Benz truck chassis, the 231 first entered service in 1932. Its ancestry was both visible and problematic. It looked like a civilian automobile, in that unlike the 222, its engine was up front and vulnerable even given the well-sloped 14.5mm armor. At almost six tons, the weight was too heavy for the chassis, and the suspension was a constant source of concern despite the good road speed of 40 miles per hour. Like the 222, it was easy to manufacture—a thousand were created by the time production ceased in 1935. But even more than the Panzer I, the Armored Car 231 was used as a training vehicle and relegated to second-line service as fast as a replacement could be made available.

  That replacement kept the designation, but was an entirely different vehicle: an eight-wheeled, rear-engineered design built on a Buessing-NAG chassis. It could do over 50 miles per hour on roads, 30 miles per hour off road. With dual steering, all-wheel drive, and independent suspension, its cross-country capacity even through sand and mud exceeded any wheeled, armored vehicle in any army, despite its relatively heavy weight. Its turret-mounted 20mm cannon and 15mm armor were adequate for the scouting mission that was its fundamental purpose, and from its first entry into service in 1938, the Achtrad “eight-wheeler” was popular with its crews. The complexity that made it difficult and expensive to manufacture was an acceptable tradeoff, especially given the increasing quality of unit-level maintenance in the Panzer arm. The new 231’s major tactical drawback was its size. At seven feet eight inches and 8.3 tons, it was not exactly suited for “sneak and peek.” For “shoot and scoot,” however, the Achtrad was unmatched during the war’s first half, and its size enabled the inclusion of a radio system that added “communication” to its long list of positives.

  The 222 and 231 spawned a long list of modifications. Most were specialized radio vehicles. The 222 in particular was too small to carry both a radio and a cannon. Its near-sister SdKfz 223 was distinguished by a smaller machine-gun turret and carried a third crew member. Both six- and eight-wheel versions of the 231 also had radio versions with frame aerials. These, perhaps because of their distinctive appearance, are disproportionately featured in illustrated works despite their relatively small numbers.

  This is one of the points in the narrative where it is tempting to dive into the permutations and modifications of design and armament that give Hitler’s panzers their enduring appeal to buffs, hobbyists, and rivet heads. There are, for example the various artillery tractors that kept the guns within supporting range of the tanks. There is even a half-track motorcycle, initially developed to tow the 37mm antitank gun. Space and discipline combine, however, to take us forward to the last major family of armored vehicles that Germany took to war in 1939—half-tracks.

  The SdKfz 251 stands with the Panzer IV at the focal point of Wehrmacht armor. Its only rival for “best of its kind” was its US army counterpart. It was a bit of a military afterthought. German infantry had regularly ridden trucks to the combat zone during maneuvers since the Reichswehr years. In the early days of the armored force, motorcycles were so popular that five of the nine rifle companies in a panzer division’s rifle brigade rode them. Trucks and c
ycles, however, shared common problems: high vulnerability and limited off-road capacity. On the other hand, the panzers’ commitment to the principle of close tank-infantry cooperation was reinforced by the experiences of both sides in the Spanish Civil War, when tanks operating alone in broken or built-up terrain proved highly vulnerable to infantry who kept their heads. In a 1937 exercise, the modified civilian two-wheel-drive trucks assigned to the motorized infantry performed so badly that Guderian, still a mere colonel, directly challenged the army’s commander in chief, Werner von Fritsch, to remedy the situation.

  “Had my advice been followed, we would now have a real armored force” were bold words, often cited to prove Guderian’s professional conviction, his moral courage, and his arrogance, depending on the author’s perspective. In fact, exercises and maneuvers were historically regarded as high-stress situations where such outbursts were more or less predictable, and Fritsch had a known high tolerance for young enthusiasts. Guderian, moreover, was widely understood as Lutz’s protégé (an alternate German word is Protektionskind, “favorite child”). In short, he got away with it.

  In concrete terms, Lutz and Guderian pressed for the development of an infantry-carrying vehicle with sufficient cross-country mobility to accompany tanks into action, and with enough armor and firepower to allow the crew to fight from it, if necessary. Such a vehicle had to meet two external requirements. It had to be cheap, and it could not interfere with tank production. That ruled out prima facie any kind of full-track design. Trucks were disqualified because any reasonably armored version would be heavy enough to overload suspensions and to lack off-road capacity. The answer came from the artillery—and indirectly from France.

  Even before World War I, truck companies on both sides of the Atlantic had been experimenting with replacing rear wheels with some sort of track in order to lessen ground pressure and improve mobility in mud, snow, and sand. Most prominent in this effort was French engineer Adolphe Kegresse, whose successful conversion of some of Russian Tsar Nicholas’s autos inspired the Putilov armaments works to consider a project for military half-tracks. After the war the French firm of Citroën developed several civilian versions, staging well-publicized desert crossings in North Africa and central Asia and attracting the particular attention of a French army still engaged in Morocco and southern Algeria.

  From the later 1920s, half-tracks made up a steadily increasing percentage of France’s military motor vehicles. Initially and primarily used as artillery and engineer vehicles, they found their way to the mounted troops as well. The French cavalry division as reorganized in 1932 had 150 armored versions as reconnaissance and combat vehicles. Another hundred, unarmored, carried the men and weapons of the battalion of Dragons portés (motorized dragoons) newly created for each mounted division.

  With such an example so ready at hand, as early as 1926 the Reichswehr’s Weapons Office began preparing its own design for half-track tractors. Daimler-Benz began working on a production version in 1931; by 1936, a series of vehicles from one ton to eighteen tons were on the drawing boards or in the field, mostly as artillery tractors. That reflected, in passing, the artillery’s continued reluctance to accept the urging of the Lutz/Guderian school and fully mechanize the panzer divisions’ fire support by developing self-propelled mounts. This was more than commitment to branch self-interest and a tradition of towing guns into battle. Tracked vehicles were still fragile relative to the weight and the recoil of even a light field piece like the standard 105mm howitzer. In addition to probable effects on accuracy, a breakdown took the gun out of action as well. Not until well into the Cold War would even the US army abandon towed guns as standard divisional-level weapons.

  On the bright side from the panzers’ perspective, Hanomag’s three-ton tractor seemed well suited to carry a rifle squad. The armored chassis was provided by Büssing and the fit, if not perfect, was close enough for government work. At eight tons, with between 8 and 15mm of armor and mounts for two light machine guns, the 251 was tough and durable, eventually serving as the mount for a bewildering variety of weaponry. Tracks extending to nearly three-fourths of the chassis, plus a sophisticated steering system, compensated for an unpowered front axle and gave the vehicle better cross-country abilities than its US counterpart and eventual rival.

  The technical hair in the soup of the 251 was its complexity. It may be argued as well that neither the infantry nor the panzers sufficiently internalized the need to emphasize rapid, large-scale production. The first A-model versions did not begin service trials until 1939, and there would never be enough of them to equip more than one battalion in all but a few favored panzer divisions.

  Production delays bedeviled as well the 251’s smaller cousin. The SdKfz 250 developed out of a growing mid-1930s belief that reconnaissance was too vital an element of mobile war to be trusted to existing combinations of motorcycles and armored cars. At times it might be necessary to fight for information; at times it might be necessary to traverse rough ground to secure information. The solution was a half-sized half-track built on the chassis of the 1-ton artillery tractor. At 5.4 tons, with up to 14.5mm of armor, an open top, and a six-man crew, the 250 could move at almost 40 miles per hour, cover 300 miles on a single fueling, and, when necessary, put a few boots on the ground to search, destroy, and provide fire cover. It would not see service until 1940, but eventually it would prove almost as versatile a weapons platform as the 251. And its description completes the first tranche of Wehrmacht armor.

  III

  THE STORY OF the SdKfz 250 segues neatly into the institutional development of the armored force in the second half of the 1930s. On March 15, 1936, a Weapons Office memorandum allocated three missions to the armored force: supporting the infantry attack, providing antitank defense, and carrying out independent operations in cooperation with other motorized troops. But other ideas were also percolating through the military system. The cavalry in particular had been hemorrhaging men and talent. Five of its eighteen regiments had already been transformed into tank, motorized, or motorcycle units. The rest were shedding squadrons for the new antitank and reconnaissance battalions. The Wehrmacht had plans to retain horse cavalry on mobilization, but it would take the field assigned by squadrons to infantry divisions. Small wonder that increasing numbers of talented and/or ambitious junior officers were seeking their future in the mechanized units.

  The cavalry had been the army’s social elite since the days of the Great Elector. Even in the Reichswehr years its officer corps included a high proportion of landed gentry: vons and von und zus. Its continuing influence had been highlighted by Maximilian von Weichs’s seamless move into command of the Wehrmacht’s first and only armored division. To respond to the march of progress was one thing; to fade ignominiously away was quite another.

  Military considerations shaped the cavalry’s behavior as well. German strategy was, as noted above, still predicated on the defensive. In that context there seemed to be a valuable operational role for a modern force able to perform a screening function, initially engaging and channeling an enemy while the panzer divisions lurked in reserve as a final argument. And should, as expected, the national strategy eventually require a military offensive, then mechanized reconnaissance, screening, and pursuit would be even more necessary. The argument was sufficiently persuasive that in August 1937 the Army Command informed Lutz that instead of creating additional panzer divisions, it planned to create the first of three “light divisions” in the fall of 1937.

  The short lives and undistinguished careers of these formations has somewhat obscured their intended character. Though used as such in the Polish campaign, they were not panzer divisions manqué. Nor, as is sometimes asserted, were they a direct response to the French army’s new light mechanized divisions. Their closest analogs are the armored cavalry regiments introduced in the US army’s order of battle during the Cold War era to provide mobility, firepower, and shock action at the operational-level cutting edge. The missions we
re strikingly similar: reconnaissance and screening, plugging gaps in the line, conducting delaying actions, quickly occupying vital sectors, and, finally, pursuit and overtaking of retreating enemy forces.

  The light division’s norm was three “cavalry rifle battalions” and a “cavalry motorcycle battalion,” one or two reconnaissance battalions built around motorcycles and armored cars, and a three-company light tank battalion eventually to be equipped with the later, fast models of the Panzer II. Internal signs of the division’s mission were the transporter vehicles issued to the tank battalion to facilitate operational mobility and save wear on the tanks. The number of machine guns in the rifle battalions was about double that of standard infantry—a useful tactical force multiplier in either defense or attack. Externally, no one could mistake the light divisions’ retention of the cavalry’s yellow branch color as opposed to the pink of the panzer divisions. Nor could anyone mistake the creation of a separate corps command to supervise their training and development.

  At the other end of the spectrum, the infantry was also brought under the mobile-warfare tent. It was increasingly clear that mechanization as such was having to compete with a broad spectrum of other rearmament initiatives, in the context of a regime that considered “prioritization” something of a swear word. The three authorized panzer divisions risked being submerged in a growing sea of foot- marching, horse-powered infantry—the exact kind of mass army the Reichswehr’s institutional mentality was conditioned to avoid.
