In 1901, MacLagan was
posted to Australia on secondment as adjutant of the New South Wales
Scottish Rifles and Deputy assistant Adjutant General of the 1st
Military District (New South Wales). There he married the daughter of
Major General G. A. French, Commandant of the 1st Military District. He
also met Lieutenant Colonel W. T. Bridges.
MacLagan returned to
regimental duty with the Border Regiment in England in 1904. He was
promoted to major in 1908 and transferred to the Yorkshire Regiment. In
1910 he returned to Australia at the request of Bridges as director of
drill at the new Royal Military College of Duntroon. He was promoted to
lieutenant colonel on 20 January 1911.
MacLagan was still at
Duntroon when the war broke out in August 1914. He was appointed to the
AIF on 15 August 1914 with the rank of colonel commanding the 3rd
Infantry Brigade. He embarked for Egypt on 21 October 1914 on HMAT Orvieto.
As the next most senior regular officer in the division after Bridges
himself, it was natural that Bridges should turn to MacLagan to lead the
assault on Gallipoli. MacLagan regarded this as a dubious honour and was
dubious about the prospects of the operation. Both Bridges and
Lieutenant General W. R. Birdwood considered MacLagan pessimistic, a
view shared by many historians.
Landing with the second
wave of the 9th Battalion on the morning of 25 April 1915, MacLagan was
thrust into one of the most chaotic situations imaginable: a major
landing on a wrong beach. MacLagan grasped the importance of the ground
and began changing the plan accordingly, but perhaps influenced by his
belief in the impossibility of the operation, failed to press vigorously
and gave orders to dig in on the second ridge. For his decisive action
on the first day, MacLagan was mentioned in dispatches.
Bridges felt that
MacLagan was so exhausted by the second day that he sent Colonel H. N.
MacLaurin to relieve him. After a brief rest, MacLagan rejoined his
brigade in the southern sector of Anzac. On 25 May 1915, MacLagan was
hospitalised, returning on 4 June 1915. He was evacuated again, this
time with dysentery. He was evacuated to England and only rejoined his
brigade at Tel el Kebir, Egypt on 1 January 1916 after the evacuation of
Anzac.
MacLagan embarked at
Alexandria for France on 27 March 1916, arriving at Marseilles on 3
April 1916. He commanded the 3rd Brigade at Pozieres and Mouquet Farm,
where it suffered heavy casualties. On 20 November 1916, he came down
with a severe case of the flu and was evacuated to England. Owing to
complications, he was not cleared by the medical authorities.
On 22 January 1917,
MacLagan took over command of the AIF Depots in the United Kingdom from
Major General Sir N. Moore, who was ill. MacLagan was mentioned in
dispatches and on 2 February 1917, he was made a Companion of the Bath
(CB). In June he was superseded as commander of the AIF Depots in the
United Kingdom by Major General J. W. McCay, who was appointed by the
Australian government. MacLagan then became Director of Military
Training on 22 June 1917.
On 16 July 1917, MacLagan
was promoted to major general and appointed to command the 4th Division,
vice Major General W. Holmes, who had been killed in action. The
division was at a low ebb at the time, having taken heavy casualties at
Bullecourt and Messines, and missing out on the rest given to other
divisions. It was now alerted for participation in in the new campaign
in Flanders, Third Ypres.
MacLagan had little time
to do anything, but his division fought well at Polygon Wood in
September. At the end of the year, the division's casualties for the
years were reckoned at 116% of the division's strength; a loss exceeded
by only six other divisions on the British Front, including the 3rd
Division (135%). The 4th Division was withdrawn to become a depot
division but although denied reinforcements except for its own returning
wounded, it was gradually built back up to strength.
Strangely, it was the 4th
Division that was first committed to the battle in March 1918 when the
German Offensive struck the British Armies on the Somme sector. It was
the 4th Division met and defeated the Germans at Hebuterne, Dernancourt
and Second Villers-Bretonneux. On 4 July 1918, MacLagan directed the
brilliant Australian and American attack on Hamel. In the attack on the
Hindenburg Line on 18 September 1918, the 4th Division was halted short
of its objective. MacLagan rested his men, sent forward a hot meal and
then resumed the attack, capturing the objective. In late September,
MacLagan was sent to the US II Corps as head of a group of 217
Australian advisors to the Americans, coaching the Americans through an
attack on the Hindenburg Line. For his services in 1918, MacLagan was
mentioned in dispatches three more times, bringing his total to five.
One of only five seconded
British officers to remain with the Australian Army throughout the war,
MacLagan was discharged from the AIF on 20 May 1919. He was promoted to
major general on 1 January 1919 and was made a Companion of St Michael
and St George (CMG). MacLagan commanded the British 51st (Highland)
Division from 1919 to 1923. He retired in 1925 and died in Dundee,
Scotland in on 24 November 1948.
