Nolan had minimal respect for officers who owed their rank to aristocratic lineage, and so made little effort to hide his contempt for Lucan, the cavalry division commander. There are your guns! Lucan consequently ordered his two cavalry brigades to charge the guns at the east end of the valley; he did not include the horse artillery troop Royle The Light Brigade continued forward alone for 8 minutes across a mile-and-a-half of open terrain.

Despite staggering losses, the unit reached the Russian position and overran the guns. But the survivors were too few to hold out against the nearby Russian cavalry, and after about 4 minutes of melee the British retreated back through the valley. This withdrawal marked the end of the battle. The Russians claimed a victory, since they had captured and held the redoubts. Emboldened by this success, they launched a larger attack at Inkerman 11 days later to try to relieve Sevastopol more directly.

That battle ended in a stalemate, however, and subsequently the Russian field army suspended activities for the winter. For their part, the British had avoided outright defeat by retaining their supply port at Balaclava.

But the loss of the redoubts restricted their flow of supplies between the port and the siege works Ponting This slowed the transport of food, clothing and fuel to the troops, and so aggravated their attrition during the ensuing winter. By comparison, if the British had won the battle, the redoubts and roadway would have returned to their control, so that their supply line and winter attrition would have been less perilous. Furthermore, a twice-beaten Russian army might not have launched its later assault at Inkerman.

Counterfactual Research and Mathematical Models This paper explores counterfactual histories that could have emerged if the British commanders had made different decisions.

Historians have sometimes dismissed counterfactual analysis as little more than conjecture. In recent years, however, these analyses have become more common, in part because scholars like Tetlock and Belkin argue that we can learn interesting things about the actual past by exploring hypothetical alternatives to it. Hawthorne suggests that examining potential pasts helps us to realize that the trajectory of history is not an inevitable one. They used an agent- based model computer simulation to study the reasons for the British victory at the Battle of Trafalgar.

They first designed the model so that it would reproduce the results of the actual battle. Their results indicate that if the British had employed a different plan, they still would have won the engagement, but with a greater loss of ships and crew. Another way to model a battle is with mathematical equations, such as those developed by Frederick Lanchester see, e. Lanchester equations provide a simple way to represent opposing forces that gradually wear each other down via attrition.

They can model, e. Lanchester equations are less suitable for battles with distinct waves of firepower, such as with airstrikes or missile salvos. For such situations, Hughes developed a set of equations called the salvo combat model. This model first adds-up the attacks being launched; e. It then subtracts the number of interceptions made by the defender; e. The resulting difference, if positive, indicates the number of attacks e.

The loss inflicted on the defender is the sum of the damage caused by these hits. Armstrong consequently developed a stochastic or probabilistic version of the model that allows for random variation in the success of each attack, the success of each interception, and the damage caused by each hit.

This stochastic salvo model can be used to estimate the average and standard deviation of the losses suffered, as well as the probabilities of various outcomes. For example, Armstrong and Powell used the stochastic model to examine decisions made by US Navy admirals leading up to the Battle of the Coral Sea. They calibrated the model using data about aircraft losses, bomb hits, etc. Their results suggest that dispersing the American carriers into separate task forces would likely have reduced their losses.

They also found that adding another American carrier would have greatly increased Japanese losses, but only slightly decreased American losses. A follow-up study Armstrong found that being able to attack first, rather than simultaneously, would have been more valuable than an extra carrier. In this paper we use salvo equations, rather than Lanchester equations, for two reasons. Second, Lanchester equations assume that both sides inflict casualties simultaneously, whereas cavalry only get to attack their targets after enduring defensive fire during their charge.

Our versions of the salvo model equations are simpler those than in Armstrong and Powell because we have no defensive interceptions to deal with.

The equations were implemented in Excel software for convenience; copies of the spreadsheet are available upon request from the authors. An earlier version of this study also used an agent-based model, and found that both approaches gave similar results; see Connors It then sums the average loss per shot to get the total casualties inflicted. These are subtracted from the initial British strength to get the number of cavalry that survive the cannon fire and so can melee with the Russian forces.

The total number of hits i. The parameters are chosen so that the average being constant; so the loss per hit is treated as an independent and identically distributed random deterministic model; i.

The equations to calculate its mean and variance are well established see, e. The limits are calculated by assuming that the survivor distribution is approximately normal as in, e. Unlike computer simulations, however, our model does not contain any random elements itself.

Scenario 1: The Light Brigade Charges along the Valley Our modeling begins with the historical attack, in which the Light Brigade charged the Russian cannon at the east end of the valley. The first step is to calibrate the model by estimating the equation parameters. The approach is analogous to using a weigh scale. One starts by weighing objects of known weight; this calibrates the scale, so that it can then be used to measure objects of unknown weight.

In the present case, we ensure that the model reproduces the outcome of the actual battle, before applying it to the counterfactual scenarios. We especially refer to Adkin because he provides detailed numerical estimates for many of our parameters; we are forced to rely on approximations for some of the remainder. The next sub- section describes these values. As in Armstrong and Powell and Hughes , this figure includes all combatants knocked out of battle, not just those who died.

After stragglers trickled in, the brigade reported men killed, wounded, or captured. Also lost were horses; Adkin It is clear from historical accounts that most of the casualties occurred during the charge itself, rather than during the ensuing melee and retreat; but the exact division between the former and latter is unknown.

As an approximation, we assume that all of the British casualties occurred during the charge itself. This is a conservative approach, in that the resulting formulas will slightly overestimate the effectiveness of the Russian guns. We do not include any British cannon in our analysis.

We consequently exclude it from the other counterfactual cases as well Scenarios 3 and 4. They were set up on the Fedioukine Heights north of the valley. Adkin estimates that their 10 guns fired about 7 times each 2 shots per minute for 3. More flanking fire followed from the 7th Battery of the 12th Artillery Brigade, which was deployed near Redoubt 3 on the Causeway Heights south of the valley.

Adkins suggests their 8 guns fired about 4 rounds each as the British rode past, for a total of 32 shots. The target of the charge was the 3rd Battery of the Don Cossacks Brigade, which was lined up across the east end of the valley. Adkin estimates that each of their 8 guns would have fired about 11 shots head-on into the Light Brigade, for a total of 88 shots. Table 1. Some of these rounds would have missed the target, and the ones that did hit would have caused varying numbers of casualties.

Since historical records do not precisely describe the results of most individual cannon shots, some assumptions in this regard are necessary. This implies that each successful hit would have inflicted an average loss of 4. Finally, we set the standard deviation of the loss per hit at one-third of the average, i.

Any cavalry that survive the charge will be able to attack the Russian gunners with their sabers and lances, but we will not calculate the resulting gunner casualties here, as historical sources do not detail them. The reports do make it clear that the entire battery was at least temporarily overrun. We also need to account for the Russian cavalry force located behind the guns in the valley. Instead, their numbers will provide important context when interpreting the model outputs.

These 20 squadrons had an estimated men at the beginning of the day Adkin , but lost about during an initial skirmish with the Heavy Brigade Ponting This force was then reinforced by 4 additional squadrons of Cossacks Adkin Model Outputs Our equations use this data to estimate the effect of the Russian cannon fire on the British cavalry. The model guns. This naturally matches the historical outcome, because we specifically calibrated the inputs to reproduce that outcome.

Table 2. Model inputs and outputs by scenario Light v. Both v. Light v. That is, if the charge were re-fought many times the same way, how widely could we expect the outcomes to vary? Figure 1 is a histogram that illustrates this potential variation. On the other hand, those differences are too small to have made any meaningful difference in the overall outcome of the charge.

Figure 1. There is ample evidence to indicate that these units lacked an appetite for fighting. However, the Russians regained their composure once they realized how few British remained. The former outnumbered the latter to , or about to Even if the British had been lucky enough to have survivors i. Scenario 2: The Light and Heavy Charge along the Valley Next we use the calibrated model to analyze a counterfactual scenario in which the Heavy Brigade joins the Light in a combined charge along the valley.

The historical attack actually started this way, but then Lucan changed his mind. Model Inputs To model this situation, we add cavalry for the British and cannon volleys for the Russians. The Heavy Brigade started the day with about soldiers, but suffered 97 casualties in an initial skirmish with the Russian cavalry Adkin So the British gain more cavalry, roughly doubling their total to With twice as many British units passing sequentially through the valley, the Russian battery on the Causeway Heights would have had twice as many opportunities to fire; hence we double its volleys from 4 to 8.

We also increase the shots by the Fedioukine Heights battery, but only by 1 volley, from 7 to 8. Those guns had just begun firing at the Heavy Brigade in the actual battle, but then were silenced by the French cavalry. Britain and France feared Russia would continue pushing down, and eventually come into British India through Afghanistan. Due to miscommunication, the Light Brigade was instead sent on a frontal assault against a different artillery battery, one well-prepared with excellent fields of defensive fire.

Thus, the assault ended with very high British casualties and no decisive gains. Published just six weeks after the event.

Its lines emphasize the valour of the cavalry in bravely carrying out their orders, regardless of the obvious outcome. Blame for the miscommunication has remained controversial, as the original order itself was vague. Charge for the guns' he said: Into the valley of Death Rode the six hundred.

Not though the soldier knew Some one had blundered: Theirs not to make reply, Theirs not to reason why, Theirs but to do and die, Into the valley of Death Rode the six hundred. So half a league is roughly a mile and a half. It explains that the cavalry moved a mile and a half in a single move. It also sounds like a military march: Left!

Left, right, left! The battle was like the Valley of Death. The Russian gunmen were at the head of the valley looking down from a strong vantage point at the cavalry; the BriJsh had liKle hope of victory. Charge for the guns!
