Belgium and France At the outbreak of the Second World War, Horrocks was working as an instructor at the Staff College, Camberley, where he had taught since 1938. After helping organise a new, shorter, officer-training course, in December 1939 he was promoted to substantive lieutenant colonel. The following May, he was despatched to France to command the 2nd Battalion, Middlesex Regiment, a machine-gun battalion directly subordinate to the
3rd Division headquarters of
Major-General Bernard Montgomery. British
doctrine at the time retained heavy machine guns under the direct command of a corps or division, rather than as an organic part of subordinate formations. He joined the battalion during its
retreat to Dunkirk, and after only 17 days had impressed his superiors sufficiently to be given the temporary rank of
brigadier, and the command of
11th Brigade. The brigade's previous commander,
Kenneth Anderson, had been promoted to
General Officer Commanding (GOC) 3rd Division during the
evacuation, when
Lieutenant-General Alan Brooke, commander of
II Corps, was recalled to the United Kingdom and Montgomery took over the corps.
Home service On Horrocks' return to Britain, he was given command of
9th Brigade and assigned to defend against a possible German invasion. He was promoted to substantive colonel on 28 May 1941 (with seniority backdated to 1 July 1940). The 44th Division, composed of the
131st (Surrey),
132nd (Kent) and the
133rd (Sussex) Infantry Brigades together with supporting units, was stationed in Kent preparing to repel the expected
German invasion of the United Kingdom. The division was responsible for the southern Kent coast east of
Folkestone and was serving under the command of
XII Corps, commanded by Montgomery, who secured for Horrocks his new command. In March 1942, Horrocks was given command of the newly formed
9th Armoured Division and gained the temporary rank of major-general on 27 June. Horrocks, an infantry soldier with no experience in dealing with cavalry, was an unusual choice for commander of an armoured division. He trained the division hard, organising exercises to improve the effectiveness of his troops, and to familiarise himself with
armoured warfare. Despite never having commanded a division in battle, he was further promoted to acting lieutenant-general and sent to Egypt to command the
Eighth Army's
XIII Corps, under Montgomery.
General Sir Harold Alexander and Lieutenant-General Montgomery had decided to make a "clean sweep" when replacing the dismissed General Sir
Claude Auchinleck as
Commander-in-Chief (C-in-C)
Middle East and Eighth Army commander respectively. Officers perceived to have failed under the old regime were removed, and Montgomery's favoured commanders were brought in. Among these was Horrocks, as Montgomery later explained:
North Africa , the new commander of the British Eighth Army, and Lieutenant-General Brian Horrocks, the new GOC XIII Corps, discussing troop dispositions at
22nd Armoured Brigade HQ, 20 August 1942. The brigade commander, Brigadier
Philip Roberts, wearing beret, is on the right. On arriving in North Africa, Horrocks' corps was ordered to defend the
Alam el Halfa ridge in northwestern Egypt from an expected attack by the
Afrika Korps. Concerned that heavy casualties would jeopardise his planned
El Alamein offensive, Montgomery instructed Horrocks to repel
Erwin Rommel's forces "without getting unduly mauled in the process". Horrocks prepared for a purely defensive battle, with his armour dug in around the ridge. When the Germans attacked on 30 August, they failed to lure the British tanks towards their
88 mm guns—a tactic that had previously been used with great success—and found themselves battered by both artillery and the
Desert Air Force (DAF). The battle ended with the Germans in control of Himeihat hill, but at a high cost, and the Allied forces unwilling to try to re-take it after a failed attack by the
2nd New Zealand Division. The army's defensive success raised morale, and Horrocks was praised by his subordinate, Brigadier
Philip Roberts, for his "wonderful knack of inspiring confidence and enthusiasm wherever he goes". Montgomery, too, was pleased, saying "he deserves great credit for his action on that day". ,
44th Division and the 1st
Free French Brigade of Horrocks' XIII Corps made a
feint to the south. Horrocks was offered the command of
X Corps, an armoured corps, in the planned Alamein battle. He refused it, believing that Major-General
Herbert Lumsden, a cavalry officer, would be more suited to the role. Instead he retained command of XIII Corps, and was given the task of making a feint to the south to deceive
Axis forces, while the main thrust was made by
XXX Corps and X Corps to the north. Montgomery told Horrocks that he was not to incur tank losses, so XIII Corps' offensive operations were limited to raids. , GOC

X Corps, Lieutenant-General Montgomery, Lieutenant-General Brian Horrocks, GOC XIII Corps In the aftermath of the landmark British victory that followed, Horrocks' corps was assigned to the reserve and was reduced in size while the rest of the Eighth Army pursued the retreating Axis forces, "while poor old 13 Corps became the 8th Army's Mrs. Mopp, left behind with the unpleasant task of clearing up the battlefield of Alamein". At one point the only formation under his command was a salvage unit clearing the wreckage of the battlefield, which he visited daily. In December, he relinquished command of XIII Corps to Lieutenant General
Miles Dempsey and took over command of X Corps, the lead corps in the advance of the Eighth Army, after Lumsden's dismissal for his perceived poor performance during the pursuit. Horrocks was appointed a Companion of the
Distinguished Service Order on 31 December 1942 "in recognition of gallant and distinguished services in the Middle East". Following the fall of
Tripoli in January 1943, the remaining Axis forces retreated to defensive positions in Southern Tunisia, in front of the
Mareth Line built by France before the war. Here in March, Horrocks carried out one of his most successful actions. His corps, composed of the
1st Armoured Division, a Free French brigade and the attached New Zealand Corps (which included the 2nd New Zealand Division and the British
8th Armoured Brigade), was ordered to attack as part of
Operation Supercharge II after XXX Corps failed to breach the line. He carried out a
flanking manoeuvre through a pass judged by the Germans to be impenetrable, rendering the Mareth position untenable and forcing the Axis into another retreat. Three
Italian divisions were destroyed, and the German
15th and
21st Panzer Divisions and the
164th Division were heavily depleted. Horrocks continued to command X Corps in the following weeks before being transferred to the
First Army to take over
IX Corps after its previous commander, Lieutenant-General
John Crocker, was wounded in a training accident. Also transferred with him from the Eighth Army to the First Army were the 7th Armoured and 4th Indian Divisions and the 201st Guards Brigade, all highly experienced veterans of the desert. He led this corps in the final Allied
offensive in Tunisia during April and May 1943, capturing
Tunis and accepting the surrender of the remnants of Rommel's
Army Group Africa. He was
mentioned in despatches on 24 June, He was also given the rank of temporary lieutenant-general and war substantive major-general. In June 1943, after returning to command of X Corps, Horrocks sustained serious injuries during an air raid at
Bizerte, while watching an amphibious rehearsal by the
46th Infantry Division for Operation Avalanche, the
Salerno landings. Bullets from a
strafing German fighter struck his upper chest and carried on through his body, piercing his
lungs,
stomach and
intestines. He underwent five operations and spent fourteen months recovering.
Northwest Europe It was a year before Horrocks recovered sufficiently to tell
Field Marshal Sir Alan Brooke, the
Chief of the Imperial General Staff (CIGS), that he was "very anxious to be given another corps". Restored to the acting rank of lieutenant-general in August 1944, he was sent to France to assume command of XXX Corps during the cataclysm engulfing the trapped
German 7th Army and
5th Panzer Army in the
Falaise Pocket. Montgomery had been dissatisfied with the performance of the corps and its GOC,
Gerard Bucknall, a fellow Middlesex Regiment officer, since the
landings in Normandy two months earlier. Horrocks retained control of XXX Corps during the advance through Belgium, taking
Brussels, and at one point advanced in only six days. Supplies were a constant concern; the major French deep-water ports were still in German hands, and Allied supply lines stretched back to the Normandy beaches. Montgomery's
21st Army Group was by now operating from its ports—twice the distance
logistical planners had accounted for—so XXX Corps was diverted towards
Antwerp to secure its
docks and harbour. The city and port fell to the
11th Armoured Division in early September, but Montgomery halted XXX Corps for resupply short of the wide
Albert Canal to the north of the city, which consequently remained in enemy hands. Horrocks regretted this after the war believing that his corps might have advanced another with the fuel available. Although some doubt this could have been achieved without delays, The pause allowed the Germans to regroup around the
Scheldt River, and by the time the Allies resumed their advance, the
First Paratroop Army (General
Kurt Student) had arrived and set up strong defensive positions along the opposite side of the canal. The task of breaking the strengthened German line, which stretched from Antwerp to the North Sea along the Scheldt River, would fall to the
First Canadian Army in the month-long, costly
Battle of the Scheldt. By mid-September, XXX Corps had been diverted again, this time to the east. (right), GOC all Dutch forces under Monty's command, 8 September 1944.
Operation Market Garden In September, Montgomery, now a field marshal, made his planned ambitious thrust across the
Rhine and into the German industrial heartland, codenamed
Operation Market Garden, a priority for 21st Army Group. XXX Corps under Horrocks was to lead the ground assault, passing along a corridor held by airborne forces to link up with the British
1st Airborne Division in
Arnhem within four days. In any event XXX Corps never arrived and although 1st Airborne clung on to their tenuous position for a further five days, by 21 September almost three-quarters of the division was destroyed or captured. during an investiture at the headquarters of the commander of the 21st Army Group, Field Marshal Sir Bernard Montgomery, 15 October 1944. Field Marshal Montgomery is in foreground. Postwar analyses have been divided, some stressing a perceived lack of urgency on the part of Horrocks' men, while others note that German defences in the area were severely underestimated by
First Allied Airborne Army intelligence. Particularly important was the failure to identify the remnants of two SS Panzer divisions, which after Normandy had been sent to the Arnhem area for rest and refitting; intelligence had stated that only "a few infantry units and between 50 and 100 tanks" were in the Netherlands. However, Ultra reports revealed the movement of the 9th SS and 10th SS Panzer Divisions to Nijmegen and Arnhem, creating enough concern for Eisenhower to send his chief of staff, Lieutenant General Walter Bedell Smith, to raise the issue with Montgomery on 10 September. Montgomery dismissed Smith's concerns and refused to alter the plans for the landing of 1st Airborne Division at Arnhem. Counter-attacks by Army Group B under
Generalfeldmarschall Walter Model kept Horrocks' units on the defensive, and delayed their advance by forcing the British to halt and secure their flank. The terrain over which Horrocks' men had to move was also unsuitable, restricting the vanguard (Major-General
Allan Adair's
Guards Armoured Division) to a single narrow raised highway through flat or flooded countryside. The bridge at
Nijmegen, just from Arnhem, was not captured by the
508th Parachute Infantry Regiment on the first day as planned, and XXX Corps had to assist in its capture on their arrival in Nijmegen two days later, causing a further delay of 36 hours. Horrocks was not personally blamed for the operation's failure although he himself writes in his autobiography that "If we were slow then the fault was mine because I was the commander", further stating that "the sense of desperate urgency was there all right. There could be no doubt about that, and it was not for want of trying that we failed to arrive in time. I don't believe that any troops in the world could possibly have fought better than the Guards [Armoured Division] and the
82nd U.S. Airborne Division when they captured the bridges at Nijmegen. But, after all we were cut off three times, and it is difficult to fight with one hand tied behind you." , General
Harry Crerar, Field Marshal
Sir Bernard Montgomery, Lieutenant-General Brian Horrocks, Lieutenant-General
Guy Simonds, Major-General
Daniel Spry, and Major-General
Bruce Matthews, all pictured here in early 1945 during Operation Veritable. "It is always easy to be wise after the event but, knowing what I do now, I think it would have been better to have committed the
43rd Division on a different axis. Instead of passing them through the Guards on the 22nd, I should have ordered General
Thomas [GOC 43rd Division] to carry out a left hook across the lower Rhine much farther to the west and so attack the Germans, who were engaged with the 1st Airborne Division, from behind. This might well have been successful but even then I must emphasise that we should only have been able to establish a bridgehead position on the north bank of the lower Rhine. We could not have advanced any farther as envisaged in our original orders. The failure at Arnhem was primarily due to the astonishing recovery made by the German forces after their crippling defeat in Normandy." "Even if the 2nd German S.S. Panzer Corps had not been in a position to intervene so rapidly, and if we had succeeded in getting right through to the Zuider Zee, could we have kept our long lines of communication open? I very much doubt it. In which case instead of 30 Corps fighting to relieve the 1st British Airborne Division, it would have been a case of the remainder of the 2nd Army struggling desperately to relieve 30 Corps cut off by the Germans north of Arnhem. Maybe in the long run we were lucky." During the operation and for several weeks after the U.S. 82nd Airborne Division, commanded by
Brigadier General James M. Gavin, came under Horrocks' command, and Gavin, impressed by Horrocks, later wrote of him: In the aftermath of the failed operation, XXX Corps, which also had the
U.S. 84th Infantry Division under command in its first battle, took its first German town,
Geilenkirchen, as part of
Operation Clipper. The corps was temporarily commanded by Major-General Ivor Thomas of the 43rd Division. at the Europa Docks in Bremen, 27 April 1945. In early 1945, XXX Corps, now transferred from Dempsey's British Second Army to
Harry Crerar's
First Canadian Army, took part in
Operation Veritable, during which the
German Army was forced back over the Rhine. The corps employed firepower on a massive scale, and "every trick that had been learnt during the past two and a half years was brought into play, and several new ones added". For a short period XXX Corps had nine divisions under its command. Before the operation, Horrocks accepted an offer to use
Bomber Command to attack the town of
Cleves, assisting the advance of the
15th (Scottish) Infantry Division. The bombers released of high explosive that devastated the town. Horrocks later said that this had been "the most terrible decision I had ever taken in my life" and that he felt "physically sick" when he saw the bombers overhead. Operation Veritable was successful; by the evening of 9 February (D+1) XXX Corps had broken through the
Siegfried Line and into Germany with only light casualties. Aided by Lieutenant-General
Neil Ritchie's XII Corps to its right, XXX Corps began
crossing the Rhine on 23 March, and, although there was a foothold which had been established, the enemy put up strong resistance, notably at the town of
Lingen on the
Dortmund–Ems Canal. He was honoured by the governments of Belgium (the
Croix de Guerre 1940 with Palm and
Grand Officer of the Order of the Crown with Palm), France (
Croix de Guerre and
Commandeur of the Légion d'honneur), the Netherlands (Knight Grand Officer of the
Order of Orange-Nassau), Greece (Commander of the
Order of George I), and the United States (
Legion of Merit). On 12 April 1945, Horrocks met with two German officers just outside the town of
Winsen during a ceasefire. A document setting out the terms of a no-fire zone around the
Bergen-Belsen concentration camp was typed out and signed by both parties. On the day the camp was liberated by the British Army (15 April 1945), Horrocks organised the rescue of the thousands of inmates by rounding up all the food stores, water trucks and army medical services he could get hold of quickly. ==Post-war career==
