Editing Martinus Antonius Johannes Paap (section)

=== Second World War ===

Martinus served during the [[Invasion of Poland]] in September 1939 and received the Clasp to the Iron Cross, 2nd Class.

From 30 September until 30 November 1939, he temporarily commanded the [[7. Infanterie-Division]] during its transfer from Poland to the Lower Rhine. He remained on the Western Front during the winter of 1939–1940.

==== France ====

On 1 March 1940, Martinus was promoted to ''Generalmajor'' and appointed commander of the [[31. Infanterie-Division]]. When the German offensive in the west began on 10 May, the division crossed Belgium and advanced toward [[Liège]]. It later fought around the Dyle near Wavre, continued toward the Scheldt and Lys, and entered France.

During fighting on the [[Aisne]] in June, the division's first attempt to establish a crossing failed under French resistance. Martinus went forward to the regimental command posts, altered the crossing point and shifted the available artillery support.

The renewed attack established a bridgehead. Martinus committed additional infantry across the river and expanded the position before continuing the advance. He received the Clasp to the Iron Cross, 1st Class and was awarded the [[Knight's Cross of the Iron Cross]].

After the French armistice, Martinus visited [[Julien van Noord]] in [[Paris]]. Julien had been his closest friend since the beginning of the century, and the two had maintained their friendship through visits and correspondence.<ref name="julien"/>

Martinus was promoted to ''Generalleutnant'' on 1 September 1940. Later that month, the 31st Division was transferred by rail from France to occupied Poland.

==== Soviet Union ====

The division remained under Martinus when [[Operation Barbarossa]] began on 22 June 1941. It participated in the opening advance associated with the [[Battle of Białystok–Minsk]].

During a Soviet breakout attempt near the [[Zelvianka]] in late June, Martinus moved forward to a threatened battalion command post. Soviet infantry penetrated far enough to threaten the headquarters itself. Martinus shot two Soviet soldiers with his service pistol before returning to the direction of the local defence.

During the [[Battle of Smolensk (1941)|Battle of Smolensk]], a Soviet attack on 25 July broke through part of the sector held by Infanterie-Regiment 82 and disrupted contact between several positions.

Martinus rejected a broad withdrawal. He redirected divisional artillery against the penetration, moved reserves against its flank and committed Panzerjäger-Abteilung 31 against Soviet armour. He went forward to Infanterie-Regiment 82's headquarters while the counterattack was underway. By the end of the fighting, the penetration had been contained and contact between the regiment's battalions restored.

During the [[Roslavl–Novozybkov offensive]] in September, Martinus received authorization for a limited pursuit after Soviet attacks opposite his sector had weakened. His division advanced approximately 40–50 kilometres beyond its previous positions and established an exposed salient west of [[Bryansk]].

Higher headquarters ordered him to stop. Martinus argued against abandoning the captured ground and received permission to hold the position until neighbouring formations caught up.

When [[Operation Typhoon]] began on 30 September, Martinus resumed the advance. His division crossed the [[Bolva]] and continued east.

Around 19–20 October, Martinus reached [[Belyov]] and began operations against the [[Oka]]. Assault infantry crossed during the night using boats and improvised crossings before engineers expanded the route.

His command continued through [[Odoev]] and the [[Krapivna]] sector toward [[Tula]]. By 29 October, Martinus had reached the western approaches to the city.

His division attacked from the west when the wider German assault began on 30 October. By 1 November, Martinus had established a foothold in western Tula. He expanded the penetration over the following days, and forces under his command captured the city on 6 November 1941.

Following the capture of Tula, Martinus permitted [[Sonderkommando 7b]] to enter the city and did not interfere with its arrests and killings. His command also implemented the [[Commissar Order]] against captured Soviet political commissars. These actions later formed part of the case brought against him after the war.

Martinus resumed the northern advance on 8 November. His forces captured [[Kashira]] on 15 November despite growing losses and deteriorating supply conditions.

After a command conference at Kashira on 17 November, his advance continued through [[Stupino]] and the [[Mikhnevo]] sector. Martinus captured [[Domodedovo]] on 29 November.

On 1 December 1941, his leading formations reached the [[Vidnoye]] sector south of Moscow. Martinus went forward with the leading regimental headquarters. His command had advanced closer to central Moscow than that of any other German general during the campaign.

Martinus was promoted to ''General der Infanterie'' on 2 December and given temporary control of an enlarged formation known as ''Gruppe Paap'', centred on the 31st Division and reinforced with supporting units.

The Soviet counteroffensive forced him to abandon the southern approach to Moscow several days later. Martinus organized a phased withdrawal through Domodedovo, Mikhnevo, Stupino and Kashira toward Tula. Most of the organized force escaped the exposed salient without being encircled.

He received the Oak Leaves to his Knight's Cross in December 1941.

==== Higher command ====

On 20 January 1942, Martinus became commanding general of the [[XXXXIII. Armeekorps]]. He inherited the corps during the continuing Soviet winter offensive.

Martinus directed a withdrawal toward the [[Yukhnov]] and [[Spas-Demensk]] area, shortening positions that could no longer support one another and using local counterattacks to keep important roads open. By April, the corps front had stabilized around Spas-Demensk.

On 15 July 1942, Martinus was appointed commander of the [[2. Armee]]. He took command during the fighting around [[Voronezh]] and later organized the army's positions along the Don.

Martinus retained part of the army as an operational reserve and opposed attempts to remove the final mobile formations from his command while German forces farther south became increasingly committed around Stalingrad.

In late October 1942, two Soviet partisans ambushed Martinus's staff car in the army rear. His driver was killed and Martinus was grazed by a bullet. He left the vehicle and shot both attackers with his service pistol. His wound was treated without removing him from command.

During the [[Voronezh–Kastornoye offensive]] in January 1943, Martinus concluded that existing stand-fast orders threatened to trap substantial parts of 2. Armee. He began withdrawing exposed formations before receiving authorization for a general retreat.

The reserves he had retained were used to hold open withdrawal routes. The army lost substantial equipment, but much of its personnel escaped the developing encirclement. Martinus was relieved of command on 3 February 1943 because he had ordered the withdrawal without authorization.

After several weeks in the ''Führerreserve'', Martinus returned to field command on 20 March as commander of the [[15. Armee]] in France.

The Pas-de-Calais sector contained a particularly dense concentration of coastal defenses. Martinus nevertheless considered the available mobile reserve insufficient for responding to a successful Allied landing. He spent much of 1943 inspecting defensive positions and reorganizing forces behind the coast.

In December 1943, Martinus accompanied [[Erwin Rommel]] during an inspection of the defenses. They agreed on further strengthening of coastal positions but differed over how much strength should remain mobile behind the beaches. Martinus and Rommel nevertheless developed a close working relationship.

Martinus was promoted to ''Generaloberst'' on 1 January 1944.

During the first months of 1944, Martinus became increasingly convinced that the Allied invasion might take place in [[Normandy]]. When the [[Normandy landings]] began on 6 June, he considered them the main invasion and requested permission to release formations from the Pas-de-Calais. The [[346. Infanterie-Division]] began moving toward Normandy on 7 June.

==== Normandy ====

On 28 June 1944, following the death of [[Friedrich Dollmann]], Martinus was appointed commander of [[7. Armee]].

During July, he concentrated on the deteriorating German position around [[Saint-Lô]]. By 17 July, Martinus considered the most exposed positions untenable and began preparations for a controlled withdrawal before the town fell on 18 July.

On 24 July, American bombers struck the [[Panzer-Lehr-Division]] sector during the aborted opening of [[Operation Cobra]]. Martinus regarded the bombardment as preparation for a larger offensive and authorized the movement of headquarters elements and part of the reserve away from the most exposed area.

The main bombardment on 25 July still caused heavy losses. Martinus used the surviving formations to establish another defensive line and concentrated available mobile forces around the approaches to [[Villedieu-les-Poêles]]. The immediate American drive toward [[Avranches]] was temporarily contained.

As Allied pressure increased, Martinus ordered a planned withdrawal from Avranches on 10 August. By 12 August, he had concluded that continued resistance farther west threatened to trap 7. Armee around Falaise.

Transport, headquarters elements and other rear formations began moving east before a general withdrawal had been authorized. Combat formations followed. By the time wider authorization for retreat was issued on 16 August, much of Martinus's army was already moving toward the remaining routes out of the threatened area.

Heavy equipment was lost during the withdrawal, but most of the surviving personnel of 7. Armee avoided entrapment inside the [[Falaise Pocket]].

==== Netherlands ====

On 5 September 1944, Martinus was appointed [[Wehrmachtbefehlshaber in den Niederlanden]].

When [[Operation Market Garden]] began on 17 September, he identified the bridge at [[Arnhem]] as the immediate objective of the British airborne force and directed available German units toward the city.

During 18–20 September, Martinus coordinated attacks against the British position around the northern end of the bridge. Reinforcements were moved into Arnhem while the isolated British force became increasingly difficult to supply.

On 21 September, forces under Martinus fully retook Arnhem and cleared the remaining British position around the bridge. He then redirected available forces toward the British perimeter at [[Oosterbeek]]. The remaining British airborne troops withdrew during the night of 25–26 September.

After Arnhem had been retaken, Martinus inspected German positions north of the city on 21–22 September. Houses were being constructed behind the defenses for fathers attached to an SS armoured division. These buildings later became the first houses of [[Vriendendam]].<ref name="vriendendam"/>

On 10 November 1944, Martinus was appointed commander of [[Army Group H]], covering the Netherlands and the northwestern approaches to Germany.

==== Final months ====

In February 1945, [[Operation Veritable]] brought the Allied advance toward [[Kleve]], Martinus's birthplace.

Martinus went directly to the Kleve sector after the offensive began on 8 February and remained near the front as German troops were forced back toward the town. By this stage of the war, he regularly carried an [[MP 40]] during visits to forward positions.

When part of the local German line began to collapse, Martinus joined the infantry at the position while continuing to issue orders through nearby staff personnel. During the fighting on 10–11 February, he was struck in the upper torso by a shell fragment.

Martinus received field treatment and remained in the Kleve sector until the German position in the town was abandoned.

On 12 February 1945, he was promoted to [[Generalfeldmarschall]] and received the Swords to his Knight's Cross with Oak Leaves.

After the loss of Kleve, Martinus began withdrawing rear formations and equipment toward the Rhine while combat troops continued delaying the Allied advance. [[Wesel]] became one of the principal crossing areas for Army Group H.

Most organized formations crossed the Rhine during the first week of March. Martinus remained west of the river until 9 March, when he crossed after the principal rearguards had withdrawn.

[[Operation Plunder]] began on 23 March. Army Group H was severely depleted by this stage and had only a limited number of tanks and assault guns available across its broad front. Martinus avoided committing every remaining mobile unit to a general counterattack against the Allied bridgeheads.

He established a forward command post in the Wesel sector. On 24 March, [[Operation Varsity]] placed Allied airborne forces east of the Rhine around Wesel and Hamminkeln.

Airborne troops cut a road being used by Martinus and his staff. Martinus joined nearby German troops attempting to reopen the route, using the MP 40 he carried during the inspection. His staff group was temporarily isolated before contact with the rest of the German position was restored.

Martinus concluded that the Allied Rhine bridgehead could no longer be eliminated and ordered another withdrawal into northwestern Germany.

On 7 April 1945, he became [[Oberbefehlshaber Nordwest]], giving him overall command of the remaining German forces in northwestern Germany and the Netherlands.

On 4 May, Martinus personally attended the surrender at [[Lüneburg Heath]] and signed for the forces under his command. He returned to his headquarters afterward and transmitted the ceasefire orders.

The surrender took effect at 08:00 on 5 May 1945, ending Martinus's military career more than 51 years after his first enlistment.
