LIFE OF WILLIAM MILLS THE 'BOMB MAN'

When Britain went to war in 1914 the demands of static siege warfare in the trenches meant a fresh look at the ‘grenade’, particularly as the German Army had their own in plentiful supply. In early January 1915 William Mills arranged with Major Banks of the War Office to help evaluate a Belgian hand grenade, the Roland. On January 26 Mills attended a trial with Albert Dewandre, a Belgian engineer who was familiar with the Roland grenade. The Belgian armed and threw four Roland grenades which Mills had fabricated for the trial, which went badly. Major Denn, the evaluator, rejected the Roland as unsafe and unreliable. On the following day Mills discussed the rejection with Major Banks. Banks made some vague suggestions about improvements and Mills soon came to believe that an improved Roland would serve the needs of the BEF in France. By the beginning of February William Mills had used his inventive engineering skills to devise a new hand grenade based on the Roland. He was able to turn something impractical into a workable grenade. The new ‘Mills bomb’ was successfully tested at Shoeburyness on February 20 1915.

The Birmingham Mail reported in 1932…

“Only those who remember the primitive bombs used in the early days of the war can understand the delight with which the Allied troops hailed the appearance of the Mills grenade. Previously our men in the front line had been driven to strange shifts to meet the bombing raids of the enemy. Empty jam tins, even, were brought into service and proved almost as dangerous and uncertain in the hands of their users as they were to the Germans. The new missile imbued the users with confidence and even a knowledge of superiority. It was pre-eminentlysafe and easy to handle” (Birmingham Mail January 8 1932)

The ‘Mills bomb’ as it became known was an essential ingredient in arming the infantry for the siege warfare of the trenches. The British Army went to war in 1914 with a percussion grenade derived from one used by the Japanese earlier in the century. They had a sixteen inch wooden handle and to throw them in a confined space was as likely to injure the thrower as the opponent. In particular, the backswing could easily connect with the back wall of a trench and then explode. Throwing by the head reduced distance. Various types of percussion fuse were used but none were satisfactory. The consequence was improvisation and the emergence of the jam pot or jam tin bomb made from discarded items and packed with explosive and ‘shrapnel’ of all kinds. The bomb was then sealed with a wooden plug and a fuse inserted. Mills bombs had a cast iron body filled with explosive. A tube which consisted of a detonator, fuse and percussion cap ran down the centre of the grenade. An external lever, attached to a spring, restrained the striker. A pin, in turn, held the external lever. The user heldthe grenade so as to depress the lever, withdrew the pin and threw the grenade. With no pressure on the lever the striker was activated and detonated the grenade after four seconds. The first Mills was the No.5, the ‘pineapple segments would assist fragmentation’. It was later adapted to also become a rifle grenade. The shape of the No.5 fitted neatly into the clenched fist. It also had the huge advantage of being able to be safely transported with the grenade separate from the time fuse which was armed when required by front line soldiers. 

Although the Mills was the best of the wartime grenades it had numerous teething troubles. As late as mid-1916 there was still one accident for every 3000 grenades. Manufacturing faults could cause premature explosion and some pins slid out. The latter was probably the cause of the most well-known grenade accident of the war when Rifleman Billy McFadzean on July 1 1916 flung himself of a box of grenades which had fallen from a ‘shelf’. As the war developed platoons contained specialist sections which included bombers. In 1916 an improved No.23 Mark II version of the Mills bomb was introduced. It had already proved its use where the labyrinthine nature of trench defences made any advance without the clearing effect of hand grenades very difficult.

The War Diary of the 1/8^th Warwicks described their attack on the Quadrilateral near Serre on July 1 1916….

“Enemy first line reached and passed very quickly as also was the second. Only in one or two cases were any enemy seen in the two lines. Having plenty of casualties from machine-gun fire in enemy third and fourth line. All the third line men were temporarily held up by machine-gun fire but took it by rushes. From this point the fighting was all with bombs along trenches. We reached our objective probably 35-40 minutes from zero hour and at once commenced consolidating and cleaning rifles….. By this time the next battalionwas arriving but had had so many casualties that they could not go through so helped consolidating. This happened with all battalions following us. Many times we were bombed from this position and regained it until bombs ran out. We had to retire to the third line parapet and hold on with machine gun and rifle fire. Parties were detailed to collect as many bombs as could be found (both English and German) and when we had a good store we again reached our objective. No supply of bombs were coming from rear so could not hold on and retired again. Enemy machine-guns and snipers were doing a great amount ofdamage all the while. Enemy artillery opened but fortunately their range was over, Held on to this position until relieved by a battalion from rear”.

Although William Mills can only be proved to live in the Birmingham area in 1912 the 1908 Birmingham telephone directory lists William Mills Ltd at the Atlas Aluminium Works in Grove Street on Smethwick 9. This was the first aluminium foundry in the country. A 1912 Birmingham directory describes the works as producing ‘aluminium castings of every description for motor car manufacturers a speciality’. In 1917 this aluminium founders works produced castings of ‘every description for motor cars, aeroplanes and general trades’. In 1919 he chaired the James Watt Memorial Trust on the centenary of the steam pioneer’s death. He was involved with the Council of the Birmingham Chamber of Commerce and various industry bodies. The 1920electoral roll lists William and Eliza Mills as living at 14, Church Road,Edgbaston next to the Deaf and Dumb Institution. In 1925 there was still aWilliam Mills (Sunderland) Ltd at Bonners Field.

After William Mills had developed his grenade in early 1915 he opened a works to manufacture it in Bridge Street West in Birmingham which became known as Mills Munitions Limited. With other firms perhaps 75 million were produced during the war. His firm was given no preference overothers and probably made nearly four million of the total.

For his services to the war effort he was rewarded with a knighthood in June 1922 and received £27750 from the Royal Commission on Awards to Inventors. He failed in his expensive legal claim that he was not liable to pay income tax on that sumand often stated that he had lost money by the grenade. Just before his death he told an interviewer that he had lost £30000 on it.

He was a collector of pictures, china and antiques and a member of Moseley Golf Club. His wife Eliza died in May 1930; there had been no children from the marriage. She had been a member of the committee of the City of Birmingham orchestra andchairman of the Ladywood Women Unionists’ Club. William died at Edgefield, Broadoak Road, Weston-super-Mare, on January 7 1932 where he had gone for health reasons instead of his usual winter at his Riviera villa. He still owned the house in Edgbaston. A memorial services was held at Edgbaston Old Church in Birmingham where Canon Blofeld spoke of his ‘inventive genius’ and he was cremated. He was worth £37829 at his death which equated to about £1.26 million in 2005 values. In March 2002 his Knight Bachelor’s badge and War Service badge and an archive of correspondence were sold at auction.
