At 9am on October 2, the US XIX Corps began its attack with a massive aerial bombardment of German positions, followed closely by an artillery attack which included 26 artillery battalions firing almost 20,000 rounds of ammunition. The 30th Division attacked with two regiments, the 117th and 119th, abreast. The regiments had to penetrate a line of West Wall pillboxes and bunkers, and then attack through a series of small but substantial towns en route to the division’s objective for linkup with VII Corps. Over a period of five days, October 2–7, the two infantry regiments, augmented by reinforcements from the division’s 120th Regiment, made slow but steady progress. The Germans opposed every step of the 30th Division’s advance and each successful American attack was met with a focused German counterattack. General Köchling, the commander of LXXXI Corps, supported by field marshals Model and von Rundstedt, used every available unit in the corps sector to attempt to stop and reverse the American advance. All three of the understrength assault-gun brigades in the corps were used to counterattack the Americans, including the heavy King Tiger tanks of the 506th Heavy Tank Battalion. Infantry battalions were withdrawn from both north and south of the 30th Division penetration to help contain the US attack. An entire infantry regiment and six powerful antitank guns were pulled from Aachen itself to reinforce the forces fighting the 30th Division attack. In addition, the Germans assembled massive amounts of artillery to continually pound the American forward positions and the Wurm River crossing sites.
The Americans met each German counterattack, and the XIX Corps committed the 2nd Armored Division in support of the 30th Division in order to keep the 30th Division’s attack moving and to protect the lengthening north flank of the division. By October 7, the 30th Division had secured Alsdorf and the southern regiment was poised 3 miles from the objective of Wurselen. The German LXXXI Corps had expended all of its resources in its unsuccessful effort to stop XIX Corps’ attack. At that point in the battle the US VII Corps launched its attack.
By October 7, most of the German LXXXI Corps’ reserves were fully committed to the battle. This included all of the mobile elements from the assault-gun brigades, the 108th Panzer Brigade, and the 506th Heavy Tank Battalion. These were impressive formations on paper, but only actually fielded 22 assault guns, four heavy Mark VI (Tiger) tanks, and seven medium Mark V (Panther) tanks. Not an inconsequential force, but only a fraction of what the unit titles represented. It was roughly the size of a weak American armored combat command. On October 5, von Rundstedt released his theater reserves, the rebuilt 116th Panzer Division and the 3rd Panzer Grenadier Division, both divisions under command of the I SS Panzer Corps headquarters, to enter the Aachen battle. The panzer division, though not at full strength, was equipped with 41 Mark IV and V medium tanks. Both divisions had their full complement of infantry, artillery, and antitank guns. It was a significant counterattack force but would take several days to enter the battle.
On October 7, the VII Corps’ 1st Infantry Division occupied positions on the west, south, and east sides of Aachen. The Germans were supplying the city garrison along two highways which entered the city from the north. When the 30th Division captured Alsdorf on October 7 they captured one of the two highways leading into Aachen, leaving the German LXXXI Corps a single line of communications and supply into the city. The 1st Infantry Division was arrayed with all three of its regiments on line over a 12-mile front. From east to west the regiments of the division were aligned with the 16th Infantry Regiment west of Stolberg, the 18th Regiment in the suburbs just east of Aachen proper, and the 26th Regiment bending the line south along the perimeter of the city. The 1st Division’s line was filled south and west of the city by 1106th Combat Engineer Group whose engineer battalions were in the line occupying foxholes as infantry.
In the darkness of the morning of October 8, the 18th Regiment spearheaded the 1st Division’s attack to complete the encirclement of Aachen. The 16th Regiment would guard the flank of the 18th Regiment and link the division to the 3rd Armored Division defending further east in Stolberg. The 26th Regiment’s 1st and 2nd battalions would remain in position facing downtown Aachen. The 18th Regiment’s objective was a series of three hills which dominated the approach into Aachen. The attacking companies were led by special assault squads armed with flamethrowers, bangalore torpedoes, and explosive satchel charges, and specifically trained to attack German pillboxes and bunkers. In addition, a company of mobile tank destroyers and a battery of self-propelled artillery guns supported the regiment by taking the bunkers under direct fire as the assault teams closed in. Eleven artillery battalions fired in support of the assault. In 48 hours the regiment succeeded in taking all of its objectives with very few casualties. The assault teams, supported by fire from tanks, tank destroyers and direct fire artillery, closed in on the bunkers under the protection of a heavy artillery barrage. As soon as the artillery lifted, the bunkers were attacked before the defenders could recover. In this manner the first two objectives were taken. The final hill was captured by a night assault during which the US infantry infiltrated around the German bunkers and occupied the crest of the hill in darkness. The next morning the Americans mopped up the German positions from the rear. By October 10, the 18th Regiment was firmly in position north of Aachen and awaiting the linkup with 30th Division attacking south from the north. The attacks of the 1st Infantry Division left only one narrow corridor into Aachen in German hands. As the 18th Regiment consolidated its new positions, the Germans ordered the theater reserves, the 116th Panzer Division and 3rd Panzer Grenadier Division, to counterattack at Aachen.
The German reserves began positioning for their counterattack on October 10. The first attack took place on that day against the 30th Division, and included elements of the 116th Panzer. By October 15, the 3rd Panzer Grenadier was in position to attack. The attack came early in the morning and was not aimed directly at the 18th Regiment but further east, at the left flank of the 16th Regiment which had not participated in the attack to close the circle and was therefore rested and in good defensive positions. The Germans attacked in the early morning with two Panzer Grenadier regiments supported by 10–15 Tiger tanks against a single US infantry battalion of the 16th Regiment. However, the Americans were prepared and as the German infantry advanced across open ground, six American artillery battalions laid down a preplanned barrage on the exposed infantry. The artillery stopped the German infantry but the Tiger tanks rolled into the American positions and began firing on the foxholes from point-blank range. American artillery continued to pour into the German attackers as well as work back into the supporting positions preventing reinforcement and the bringing forward of supplies and ammunition. The US artillery also fired on several of its own company positions, while the infantry hugged the bottom of their foxholes, to prevent the Germans from overrunning the battalion. Air support arrived in the form of a squadron of P-47 fighter bombers in the early afternoon. The aircraft strafed the exposed German troops and finally broke the German attack. Though the American infantry could do little to stop the German tanks, the American artillery completely demolished the German infantry attacks and the German tanks were loath to advance without infantry support. That night the Germans attacked again with the same result. The attacks were broken up by heavy artillery fire even as they reached the US positions and the infantry fought hand to hand. By October 16, the 3rd Panzer Grenadier division had lost a third of its strength in attacking the lone US battalion and withdrew to regroup. Thus ended the most dangerous threat to the eastern US positions.
As the 1st Infantry Division attacked and then defended against the German counterattack, the 30th Division began its attack south from Alsdorf to link up with the 1st Division. The division attacked with all three regiments on line. The 117th Regiment in the north attacked to further establish the northern flank and protect the regiments further south. The 120th Regiment in the center attacked to secure high ground northeast of Wurselen and thus dominate approaches to the town from the north
and east. The attack of the 120th would support the attack of the 119th Regiment which would attack southeast into the northern part of Wurselen, the division objective. Control of Wurselen would effectively close the last route into Aachen and put the 30th Division approximately a mile from the westernmost element of the 1st Division’s 18th Regiment. Patrols would seal the linkup and close off German access to Aachen.
The attack to link up began inauspiciously on October 8 when the northern 117th Regiment attacked headlong into the German counterattack made by Mobile Group von Fritzschen, a hastily assembled but potent organization formed by LXXXI Corps around the 108th Panzer Brigade. The German force included numerous halftracks, several infantry battalions, Panzer IVs and Vs of the brigade, and Tiger tanks of the ubiquitous 506th Heavy Tank battalion. The objective of the mobile group was to recapture Alsdorf. Though the Germans were beaten back with severe losses by the 117th Regiment, they were successful in stopping the attack of the 117th Regiment. During the night the German infantry reverted to the defense, the 506th Tiger tanks moved south to join the attack against the 1st Infantry Division on the opposite side of Aachen, and the 108th Panzer Brigade moved south to continue the attack to expand the corridor into Aachen. On October 9, the 108th Panzer Brigade attacked again but ran into the attack of the 120th Infantry Regiment in the center of the 30th Division line. The Germans successfully blocked the American attack and seized the town of Bardenberg.
The German attack that seized Bardenberg on October 9 caused great concern in the 30th Division because it effectively isolated two battalions of the 119th Infantry Regiment which had previously secured the northern portion of the division’s objective, Wurselen. On October 10, the 119th Infantry attacked to retake Bardenberg but were unsuccessful in a daylong fight with German panzers and halftracks in the town. Meanwhile the 120th Regiment captured the road leading into the town, effectively isolating the German forces. At night the Americans withdrew from the edges of Bardenberg to allow American artillery to bombard the town. The next day a fresh American infantry battalion attacked the town and in a daylong fight captured it, in the process destroying 16 German halftracks and six tanks. The fighting in Bardenberg absorbed all of the reserves of the 30th Division and on the same day division intelligence reported identifying elements of the 116th Panzer Division in the area. General Leland S. Hobbs was justifiably concerned with his division completely committed, no reserves, soldiers tired after ten days of continuous offensive operations, and a fresh German panzer division in the area. The general ordered his center and northern regiments to halt and defend, and determined to focus the division’s efforts on the attack to secure the primary objective at Wurselen.
On the morning of October 12, the 30th Division’s attack on Wurselen had not even begun when another German counterattack hit the division. This attack was led by the panzergrenadier regiment of the 116th Panzer Division, but also included an infantry battalion of the 246th Volksgrenadier Division in Aachen, elements of the 1st SS Panzer Division (Kampfgruppe Diefenthal), remnants of 108th Panzer Brigade, and Tiger tanks of the 506th Heavy Tank Battalion, all under the control of the I SS Panzer Corps which took over responsibility of the northern German defense against the 30th Infantry Division from the LXXXI Corps. Indications to the US XIX Corps commander, General Charles H. Corlett, were that the 30th Division might be fighting two panzer divisions. All throughout October 12, the regiments of the 30th Division successfully fended off the German attacks with the help of supporting artillery and fighter-bombers.
The 30th Division resumed the attack through Wurselen on October 13 and made only very limited progress for three days. The town was defended by the 60th Panzergrenadier Regiment of the 116th Panzer Division supported by the division reconnaissance battalion and the engineer battalion as well as numerous small detachments of panzers. The American attack was on such a narrow front that the German defensive concentration was very effective and in three days the Americans barely advanced 1,000 yards. Frustrated with the slow pace of the attack through Wurselen, on October 16 the 30th Division opened a new attack, this time along the banks of the Wurm River. The attack, aided by diversions all along the 30th Division line, made rapid progress and at 4.15pm a patrol from the 119th Regiment linked up with the 1st Infantry Division, isolating the German garrison in Aachen.
For most of the time that the two-week battle over access to Aachen raged around the city, things inside the city were relatively quiet. As the Germans and Americans traded attack and counterattack outside the city, over 5,000 defenders of the 246th Volksgrenadier Division under Colonel Gerhardt Wilck waited in the center of the city for the American assault. Wilck’s force was almost entirely infantry but he did have other arms to assist in the defense including five Mark IV tanks, and over 30 artillery pieces. In addition he had access to several battalions of artillery support outside of the city. Wilck’s infantry varied greatly in quality. They included fortress garrison units and policemen who possessed minimum combat skills, as well as a company of German paratroopers and a battalion of SS panzergrenadiers. The latter two organizations were the best infantry found in the German army. Wilck’s force had ample time to set up their defense and was not surprised when the Americans began their attack.
The American forces designated for the attack into Aachen were the 1st and 2nd battalions of the 26th Infantry Regiment, 1st Infantry Division. On October 10, as the 30th Division began to make what was thought to be a quick attack to link up with the 1st Division and complete the isolation of the city, the VII Corps commander ordered that the city garrison be given a surrender ultimatum. This document, issued by General Clarence Huebner, commander of the 1st Division, promised the destruction of the city if it was not surrendered within 24 hours. On October 11, the time in the American ultimatum passed and US artillery bombardment and air strikes on the city commenced. For an entire day the bombardment continued, with over 100 guns firing over 500 tons of ammunition into the city. On October 12, the attack on the city center commenced with the 3rd Battalion, 26th Infantry (3/26) attacking on the right, and the following day the 2nd Battalion (2/26) attacked on the left. The objective of 3/26 was to cover the right flank of 2/26 and clear the industrial areas on the north side of the city. The 2/26 had the mission of attacking straight into the heart of the city center across a significant frontage of 2,000 yards filled with destroyed and partly destroyed buildings, each of which had to be cleared by the infantry. It would be a slow, systematic attack.
Prior to beginning the attack, the American commanders analyzed the situation and identified four challenges: high ammunition expenditures; command and control; thousands of civilians in the combat zone; and maximizing armor support without losing too many tanks. The ammunition problem was solved by building up battalion ammunition caches close to the assault positions so that resupply would be readily available during the attack. The command and control problem was solved by developing a specific map code where each major building and street intersection was assigned a unique code so that units could provide quick pinpoint information regarding where they were and where they needed artillery fire. The problem of civilians was answered by deciding to evacuate the entire civilian population as the units advanced through the city. This solved multiple problems: it prevented enemy combatants from hiding within the civilian population; it reduced the attacking unit’s administrative burden of dealing with the population; it reduced the possibility of the population interfering with operations; and it provided maximum protection to the population once they came under American control. The attackers planned to reduce the vulnerabilities of the American tanks by minimizing the exposure of the tanks on the major city streets. The idea was to move the tanks down side streets whenever possible, keep the infantry in close proximity of the tanks, use buildings as cover for the tanks whenever possible (firing around building corners), and finally, suppressing all enemy positions by fire whenever the tanks had to move from one firing position to another.
The Americans also adjusted their combat organization specifically for the fight in the city. In 2/26, which planned for the attack into the city central, the commander reorganized his battalion to create three self-contained assault companies. The battalion broke up its heavy weapons company and was reinforced with antitank guns from the regiment’s antitank company, and distributed these capabilities among the three infantry rifle companies: each company was provided with two additional 57mm antitank cannons, two heavy machine guns, two bazooka teams, and a flamethrower. The battalion’s attached armored support was likewise distributed among the assault companies: each company was assigned three tanks or self-propelled tank destroyers, which were then allocated, one to each of the company’s platoons. The battalion planned to attack with all three companies and no reserve. Any reserve would have to be provided by higher headquarters.
The attack technique of the American battalions going into Aachen was represented by the philosophy of 2/26 commander, Lieutenant Colonel Derrill Daniel, who told his subordinates to “knock them all down.” The basic philosophy of the battalion was to use firepower to destroy the enemy before they had to clear buildings and engage in a short-range infantry fight. Collateral damage to buildings was not a consideration in the fight, and civilian casualties were only a secondary consideration. The Americans were perfectly content to knock a building down on top of its defenders if that prevented American casualties.
By October 15, three days after beginning the assault, the two American battalions in the attack had battered their way deep into the city. American infantry avoided the streets and instead burrowed their way from building to adjacent building through the building or basement walls. American armor moved steadily down the streets but only stopped in areas protected by buildings and within a surrounding screen of American infantry support. German handheld antitank weapons, panzerfausts, were very effective against the unwary tank that exposed itself. The Americans found that many German bunkers, and even some buildings, were relatively impervious to the tank fire supporting the infantry. To increase the fire support to the infantry, both American battalions brought forward 155mm self-propelled artillery guns. These proved to be incredible psychological weapons as well as being capable of bringing down a multistory apartment building with a single round. In some cases just the threat of using the artillery gun on a position was sufficient to induce the Germans to surrender.
