Bernhardt Line The Bernhardt Line ( or Reinhard Line ) was a German defensive line in Italy during World War II . Having reached the Bernhardt Line at the start of December 1943 , it took until mid - January 1944 for the U . S . 5th Army to fight their way to the next line of defences , the Gustav Line . The line was defended by XIV Panzer Corps ( " XIV Panzerkorps " ) , part of the German Tenth Army ( " 10 . Armee " ) . Unlike most of the other defensive lines it did not run all the way across Italy but was merely a bulge in front of the main Gustav Line , running over the massif of Monte Camino , enclosing the peaks of Monte Camino ( Monastery Hill ) , Monte la Defensa , Monte la Remetanea and Monte Maggiore , in the territory of Rocca d ' Evandro , and Monte Sambúcaro , which stands at the border of the three regions ( Lazio , Molise and Campania ) . However , the defences of the Gustav Line on the Adriatic are sometimes referred to as the Bernhardt Line and the battles for this part of the line are included in this entry . The Bernhardt line was not as strong as the Gustav Line and was intended only to delay the Allies ' arrival at the Gustav Line . Together with the Gustav Line and the Hitler Line , it made up the German Winter Line defences . Background . Following the Allied invasion of Italy in September 1943 , the Italian government had surrendered , but the German Army continued to fight . The Allied armies succeeded in conquering the southern part of Italy but by early October had come up against the Volturno Line , the first of two lines ( the next being the Barbara Line ) used to delay the Allied advance to buy time to prepare the most formidable defensive positions which formed the Winter Line . Alexander had three possible alternatives to reach Rome . On the Adriatic front he could advance to Pescara and then use Route 5 ( the old Roman Via Valeria ) which traversed the country to Rome on the other coast . Alternatively , on the other side of the Apennines , highway 7 ( the old Roman Appian Way ) followed along the west coast but south of Rome ran into the Pontine Marshes which the Germans had flooded . Finally , highway 6 ran in the same direction , but further inland , through the Liri valley . Order of battle . The German forces in Italy were commanded by Field Marshal ( " Feldmarschall " ) Albert Kesselring . The defence of the Winter Line was the task of the German Tenth Army ( " 10 . Armee " ) under the temporary command of Lieutenant - General ( " General der Panzertruppe " ) Joachim Lemelsen ( in the absence of General ( " Generaloberst " ) Heinrich von Vietinghoff , who was in Germany on sick leave ) . The German 10th Army had Traugott Herr ' s LXXVI Panzer Corps ( " LXXVI Panzerkorps " ) deployed on the eastern side of Italy , from the Apennine mountains to the Adriatic , and Frido von Senger und Etterlin ' s XIV Panzer Corps ( " XIV Panzerkorps " ) on the western side , from the mountains to the Tyrrhenian sea . The new Allied Supreme Commander , Mediterranean Theatre was British General Sir Henry Maitland Wilson , replacing American General Dwight Eisenhower who had moved to command the forces preparing for Operation Overlord , the Normandy landings . Allied Armies in Italy were commanded by General Harold Alexander . Under his command were two armies : to the left , on the western side of Italy was U . S . Fifth Army and to the right , on the eastern side was British 8th Army . The U . S . Fifth Army was commanded by Lieutenant - General Mark W . Clark and consisted of U . S . , French and British units . The British 8th Army , with British , Indian , New Zealand , Canadian and Polish units , was from early January 1944 commanded by Lieutenant - General Oliver Leese when General Bernard Montgomery was also recalled to Britain to prepare for Operation Overlord . 8th Army on the Adriatic Winter Line defences . Prelude . On 3 October , a brigade of Eighth Army ' s 78th Infantry Division had crossed the Bifurno river to confront the German Volturno - Viktor Line defences . A further brigade supported by two Commando battalions landed from the sea north of the river at Termoli , and a fiercely contested battle ensued which had hung in the balance when temporary river crossings had been washed away after heavy rains and prevented Allied armour from moving forward . However , the isolated British Infantry — reinforced from the sea by a third brigade — had held out long enough against the tanks of 16th Panzer Division ( " 16 . Panzerdivision " ) for a new bridge to be put across the river and the crisis passed with the arrival of elements of British 4th and 1st Canadian Armoured Brigade s . By 6 October , the Germans were withdrawing to new defensive positions behind the Trigno river , the Barbara Line . At the Trigno , Eighth Army were obliged to pause because it had outrun its supply chain which stretched back over poor roads to the main ports of Bari and Taranto , and to its rear . Port and transport capacity had also been affected by the logistic requirements of the Allied air force which was establishing strategic bomber bases around Foggia . The Eighth Army attacked across the Trigno on 2 November . By the next day , the German position had been turned and the Germans commenced a fighting withdrawal to the forward Winter Line positions they were preparing on the ridges behind the Sangro River . Advance across the Sangro . The Eighth Army ' s forward units had reached the Sangro on 9 November . Alexander had planned for Montgomery to strike across the river on its coastal plain on 20 November with the V Corps ( Indian 8th Infantry and 78th Infantry Divisions ) . In secrecy , Montgomery shifted the Indian division to the right to narrow the V Corps front and concentrate its power , bringing the newly arrived 2nd New Zealand Division into the gap . Eighth Army also devised a deception scheme involving false troop movements and ammunition dumps to give the impression that the main attack would be through the British XIII Corps front . The deception was to be maintained by an earlier diversionary attack some inland by XIII Corps and a secondary attack at the same time as V Corps some inland by the New Zealanders . However , Kesselring divined the Allies ' intentions ; on 18 November , Lemelsen had signaled Kesselring to the effect that the Allied concentrations on the coast led him to expect the main attack on his left wing . Then heavy rain raised the river levels forcing the postponement of the offensive to the night of 27 November and giving the Germans time to switch two divisions across the Apennines to the defending LXXVI " Panzer " Corps . This made three divisions on the coastal plain opposing V Corps : 65th Infantry Division ( " 65 . Infantriedivision " ) , 90th Panzergrenadier Division ( " 90 . Panzergrenadierdivision " ) and 26th Panzer Division ( " 26 . Panzerdivision " ) . 16th " Panzer " Division opposed the New Zealanders and the German 1st Parachute Division ( " 1 . Fallschirmjägerdivision " ) faced XIII Corps ( 1st Canadian Division and British 5th Infantry Division ) . In the early hours of 28 November , the Eighth Army attack went in supported by heavy artillery concentrations . The New Zealanders advanced steadily ; although the German defences had been well prepared most of the New Zealanders ' objectives were manned by 65th Division which was poorly equipped and untried in battle . The German Division was also hampered by the fact that their commander — Brigadier - General ( " Generalmajor " ) G . H . von Ziehlberg — was severely wounded on the afternoon of 28 November . The 8th Indian Division , however , like the New Zealanders facing their first major combat action since arriving in Italy , experienced tougher opposition . Elements of 65th Infantry Division supported by an armoured battle group held tenaciously on to Mezzagrogna and the town was eventually taken on 29 November after tough , often hand to hand , fighting . On the morning of 29 November , 78th Infantry Division had joined the attack on the right of the Indian Division and had forced their way to Santa Maria by the evening , creating a base for their main attack the following day towards Fossacesia . By late on 30 November , 78th Division — supported by 4th Armoured Brigade — had taken Fossacesia , and the whole ridge on the far bank of the Sangro — carrying the main Bernhardt defences — was under Eighth Army control . As the Eighth Army pushed forward over the next few days , 65th Infantry Division crumbled ( to the extent that German 10th Army were later to order a court - martial into its conduct ) . However , Herr was able to introduce 90th Panzergrenadier Division into the line from his reserve and transferred reinforcements from the quieter sector inland in the form of elements of 1st Parachute Division . The complications of these manoeuvres introduced considerable confusion within the German alignment but they were nevertheless able to manage a fighting withdrawal to the ridge on the far side of the Moro river . Unaware of the disorganisation in the German ranks , the New Zealanders failed on 2 December to exploit an opportunity to capture Orsogna , a key position near the headwaters of the Moro , which on that day was still only lightly held . It was only on the morning of 3 December that the New Zealand Division disputed possession of Orsogna , but 26th " Panzer " had had just enough breathing space to organise and were able to repel them . The 26th " Panzer " then proceeded to create a formidable defensive complex around the town and along the ridge towards Ortona on the coast and Orsogna was not occupied by the Allies — despite a further two determined attempts during December — until the Germans withdrew after the Allied breakthrough at Cassino in May 1944 . The Moro offensive . Montgomery now rested 78th Division ( which had been leading the V Corps advance since the Volturno Line offensive ) , swapping with Canadian 1st Infantry Division from the relatively quiet XIII Corps sector . The Canadians , with Indian 8th Infantry Division on their left , led the main thrust across the Moro on 8 December aiming for Ortona . By 20 December after stubborn resistance first from elements of the 90th Panzergrenadier Division and then elements 1st Parachute Division ( which had relieved the " panzergrenadier " s ) , they had patrols on the outerskirts of the town . But the battle for Ortona took another week of fierce house to house fighting as the German 3rd Parachute Regiment tenaciously held on before withdrawing to the other side of he Riccio river on 28 December . Meanwhile , inland of V Corps , Orsogna had suffered three successive assaults but XIII Corps spearheaded by 2nd New Zealand Division could not get past the defending 26th " Panzer " Division . After advancing a total of only 18 miles ( 29 km ) and sustaining 6 , 500 casualties , blizzards , drifting snow and zero visibility at the end of December in jagged terrain caused Eighth Army ' s offensive on the Adriatic front to grind to a halt . As the New Year approached , it became clear that with no prospect of better weather until the spring , Eighth Army did not have the strength to force its way to Pescara . Alexander called a halt to the offensive , instructing Montgomery to maintain sufficient activity to pin LXXVI Panzer Corps and prevent troops from being sent across to reinforce XIV Corps facing 5th Army . The rest of the winter on the Adriatic front was spent in bitterly uncomfortable conditions with the opposing sides often in close proximity and engaged in night - time patrolling and vicious skirmishing . 5th Army Bernhardt Line offensive . It had taken U . S . 5th Army , in deteriorating weather as the torrential autumn rains broke , from the middle of October to early November to fight their way across difficult terrain and through skillful and determined rearguard defences from the Volturno Line positions to the Bernhardt Line . In the centre of the 5th Army front lay the Mignano Gap , which because of the marshy conditions on the coastal plain represented the only realistic path to the mouth of the Liri valley , the route to Rome . Flanking and overlooking Route 6 through the Mignano Gap and its villages ( San Pietro Infine , San Vittore Del Lazio and Cervaro ) are , successively Monte Camino , Monte Lungo , Monte Porchia and Monte Trocchio on the left and Monte San Croce , Monte Corno , Monte Sambúcaro and Monte Maio on the right . Monte Sambúcaro normally appears as Monte Sammucro on Allied maps of the time . On reaching the Bernhardt positions , an immediate attack was launched by British X Corps on Monte Camino on 6 November , which was beaten back by 15th Panzergrenadier Division ( " 15 . Panzergrenadierdivision " ) . By mid - November , it was clear that after having sustained 10 , 000 combat casualties since the Volturno Line offensive , 5th Army needed to pause , reorganise and re - gather its strength . U . S . 5th Army resumed its attack on 1 December . The first attack — Operation Raincoat — was delivered , after an intensive artillery and air bombardment , by British X Corps on the left ( comprising British 46th and 56th Infantry Divisions ) and elements of U . S . II Corps , including 1st Special Service Force , on the right against the formidable Camino hill mass . The dominating peak on Monte Camino , Hill 963 , is crowned by a monastery . Two slightly lower peaks , Monte la Defensa , Monte la Difensa ( Hill 960 ) as it appeared on the military maps during the war , and Monte la Remetanea ( Hill 907 ) , lie less than north of Camino . At the upper end of the Camino feature are the numerous peaks of Monte Maggiore . The entire hill mass is about long and four miles ( 6 . 5 km ) wide . On the east and northeast the slopes rise steeply to the heights , then fall away gradually to the west toward the Garigliano River . It took until 9 December before the Camino mass was secured from the 15th Panzer Grenadiers . Meanwhile , on the 5th Army ' s right flank , U . S . VI Corps ( comprising U . S . 34th and 45th Infantry Division s ) had attacked into the mountains but made little progress until reinforced by the mountain troops of the French Expeditionary Corps , recently arrived in Italy ; they attacked again on 15 December . On 8 December U . S . 3rd , 36th Infantry Divisions and 1st Special Service Force of U . S . II Corps launched the attack on Monte Sambúcaro and into the Mignano Gap . By the night of 10 December , the peaks were taken , threatening the German positions in the gap . However , the German positions at San Pietro in the valley held firm until 16 December , when an attack launched from the Camino mass took Monte Lungo . The Germans could no longer expect to hold San Pietro when the dominating ground on both flanks , Monte Lungo and the Sambúcaro peaks , was in II Corps ' possession . Under the cover of a counterattack German forces withdrew to positions about to their rear , in front of San Vittore . Several attacks were made in the next days , and Morello Hill — overlooking the San Vittore positions from the north — was captured on 26 December . On the VI Corps front , progress was made but proved very difficult over the mountainous terrain as the weather deteriorated further with the onset of winter . During the month of December , U . S . 5th Army suffered 5 , 020 wounded but total admissions to hospital totaled 22 , 816 with jaundice , fevers and trench foot prevalent . At the end of December , U . S . 5th Army had to pause once again to reorganise , replace its losses and gather itself for a final push to reach the Gustav Line defences . U . S . VI Corps was taken into reserve to train and prepare for the Anzio landings with the French troops , by this time at corps strength , taking over their front . U . S . II Corps returned to the attack on 4 January 1944 , with attacks parallel to Route 6 north and south of it . The northern attack took San Vittore , and by 7 January the overlooking height of La Chiaia . On the south side , the attack was made from Monte Lungo and captured Monte Porchia . Meanwhile on their left , British X Corps had attacked from positions on the Camino mass to take on 8 January the Cedro hill which with Monte Chiaia and Monte Porchia had formed a strong defensive line in front of Monte Trocchio . The last offensive to clear the enemy in front of the Gustav defences started on 10 January . Cervaro was taken on 12 January and the overlooking hills to the north on 13 January . This opened up the northern flank of Monte Trocchio , and a heavy assault was planned for 15 January . However , the German XIV " Panzer " Corps considered the position to be untenable and withdrew across the Rapido . When II Corps moved forward on 15 January , they encountered no resistance . Aftermath . It had taken U . S . 5th Army six weeks of intense combat and 16 , 000 casualties to advance the seven miles ( 11 km ) through the Bernhardt Line defences ( including the action at San Pietro Infine ) to take Monte Trocchio and reach the positions facing the main Gustav defences on 15 January .
