John Monash carried unfinished work forward.
On his daily agendas, completed tasks disappeared beneath a system of horizontal and vertical lines. The gaps remained. They became the beginning of the following day.
In June 1918, that habit of making responsibility visible expanded across seven typed pages headed:
SECRET. HAMEL OFFENSIVE. AGENDA.
The document moved through the coming operation piece by piece. Infantry. Artillery. Tanks. Machine-guns. Aircraft. Medical arrangements. Am******on. Food. Water. Transport. Communications. Prisoners. The clearing of the battlefield.
Each entry represented a question that had to be answered before thousands of people moved into danger.
The final conference before the Battle of Hamel brought approximately 250 officers together to work through 133 agenda items. It lasted four hours and 20 minutes. The battle that followed was expected to reach its objectives in 90 minutes.
It took 93.
Monash had taken command of the Australian Corps at the end of May. Hamel would be his first set-piece operation as corps commander, after years in which Western Front attacks had consumed enormous numbers of lives for advances often measured in hundreds of metres.
He understood the battlefield as a connected system. Infantry, artillery, tanks, aircraft, engineers, medical services, transport and supplies had to act in sequence. A failure in one part could expose people in another.
The agenda made those connections visible.
Monash had used lists for years. He allocated time to tasks, allowed for work that overran and carried unfinished items into the next day. His lists extended into packing for leave and cataloguing papers, photographs and souvenirs.
A list held information outside the mind. It gave unfinished work a visible place and allowed a person to return to a task without relying on memory or mood.
At Hamel, the same principle operated among hundreds of officers and thousands of soldiers. Tank officers, artillery officers, airmen, engineers, infantry commanders, medical staff and supply services contributed their expertise. Conference followed conference as the operation became more detailed. The surviving agenda included a separate notes column because it was built for decisions, amendments and action.
Earlier Western Front experience had given Australian infantry reason to distrust tanks. Machines had broken down, become stuck or failed to arrive. At Hamel, tank crews and infantry trained together. Tanks were paired with battalions, and battalion insignia made those relationships identifiable.
Machine-gun planning included am******on and spare barrels. Aircraft were assigned reconnaissance, bombing, contact with troops on the ground, the masking of tank noise and the delivery of am******on. Administration covered medical arrangements, engineers, food, transport, prisoners and water.
Water belonged on the same agenda as artillery and tanks. So did the movement of wounded people. So did the am******on required after the advance. The list placed the celebrated elements of battle beside the practical responsibilities that allowed people to survive and continue.
Approximately 8,000 Allied personnel were assigned to the operation, supported by about 550 guns, 60 tanks and 85 aircraft. They faced approximately 5,000 German troops.
About 1,000 American soldiers from four companies joined the attacking force. American platoons were attached to Australian companies, making Hamel the first battlefield on which Australians and Americans fought together.
Their participation almost ended on the eve of battle when six of the ten companies originally proposed were withdrawn. Monash pressed the importance of maintaining the confidence built between troops who had already trained together. Four companies went forward the next morning.
The attack began before dawn on 4 July 1918.
Artillery struck selected strongpoints while a moving barrage created a line of fire ahead of the infantry. Tanks moved with the soldiers to engage machine-gun positions and fortified points. Aircraft observed the battlefield, attacked targets and carried information. Other aircraft delivered am******on by parachute, although some parachutes failed to open. Supply tanks carried loads that would otherwise have required large numbers of people to cross exposed ground.
Each carrier tank delivered 12,500 rounds of am******on with defensive stores. Aircraft attempted to deliver another 112,000 rounds. The agenda's attention to supply continued after the attacking troops reached their first objective.
The operation advanced approximately two kilometres along a front six kilometres wide. Its principal objectives were taken in 93 minutes.
Allied forces captured approximately 1,600 German prisoners and 177 machine-guns. Total German casualties exceeded 2,000. Official figures record approximately 1,380 Australian and American personnel killed or wounded in the battle and its associated diversion, commonly rounded to 1,400 Allied casualties.
The familiar figure is a casualty total rather than a death toll. Hamel remained a violent battle, and many people paid for those 93 minutes with death or injury. Measured against the attacking infantry, the casualty rate has been estimated at roughly one person in five.
Earlier Australian battles show the scale of the burden already carried by 1918. At Fromelles in July 1916, the 5th Australian Division suffered 5,533 casualties in approximately 24 hours. The attack failed in its objectives. At Pozières, 42 days of fighting produced approximately 23,000 Australian casualties, including about 6,800 people killed or dying from their wounds.
These battles differed in commanders, objectives, terrain, technology and duration. Together, their figures show why the development of more accurate artillery, improved tanks, aerial reconnaissance, communications, rehearsal, secrecy and coordinated supply mattered. At Hamel, the whole force worked to reduce the infantry's avoidable exposure.
Every machine-gun position suppressed before soldiers reached it changed what happened to the people advancing. Every load carried by a tank reduced the need for people to carry it across open ground. Every unit that understood the timing and task of the unit beside it had a better chance of responding when the plan met reality.
Monash's operational ability existed alongside his abhorrence of war. He later described his wartime days as filled with “loathing, horror and distress.” He was also ambitious, exacting and capable of driving himself and the people under his command intensely.
Hamel reveals a commander using available knowledge, people and technology to achieve a defined objective while reducing risks that could be anticipated. His lists showed that foreseeable failures carried human consequences.
Preparation became a form of responsibility.
Near the end of the surviving document appears another heading:
AGENDA AFTER BATTLE.
It covered consolidation, reserves, relief of units, the movement of guns, the clearing of the battlefield, salvage and future responsibility for defence. Reaching the objective created another phase of work. Wounded people needed care. Exhausted units needed relief. Am******on and supplies had to move. Newly captured ground had to be defended.
A plan that ends at the moment of success leaves other people to discover what comes next. Monash's lists kept the next responsibility in view.
The Battle of Hamel is often compressed into two numbers: 90 minutes planned, 93 minutes achieved. The agenda opens those numbers and reveals the work inside them.
Leadership appears on its pages as attention to timing, equipment, specialist knowledge, communication, supply, uncertainty and the people required to carry every decision into action. It appears in the willingness to expose unresolved questions while there is still time to answer them.
Those principles extend into public and everyday life. Engineers, emergency services, community organisations, governments, businesses and families all make decisions whose consequences are carried by other people. Preparation allows risks to be found earlier. Shared plans allow expertise to meet. Visible responsibilities are harder to forget.
At Yallourn, the Sir John Monash Museum preserves the story of a man whose name became inseparable from Victoria's great electricity undertaking. The Hamel agenda offers another way to encounter him. It brings leadership down from the scale of reputation to the scale of a page: one question after another, each waiting for an answer, each connected to what somebody else would have to do.
Completed work could be crossed away.
The remaining gap began tomorrow's list.
