Mental gymnastic is rather trying to turn military disaster done by accident in to "viable tactic".
Why do you keep saying it was a military disaster? The charge ended successfully with minimal losses. You keep conflating "disaster" with "unnecessary risk". I also want to note that the charge wasn't accidental. It was an ambush. In fact, they could have still averted the charge when the ambush revealed itself and deliberately chose not to. Here are some takes on the battle from more than just your source (who himself doesn't say that the charge was a disaster, only that it was considered by many to be a strategic misstep).
UK National Army Museum said:News of this heroic charge against appalling odds captured the imagination of the public at home. Newspaper headlines in Britain read 'Gordon Avenged', and based on their reports, artists such as Edward Matthew Hale, raced to complete paintings of the victory to feed the public demand for images of the battle.
(Interestingly, the same source cites another charge - specifically Waterloo - as more proof of my claim as to the purpose of a charge and how it was executed by noting that momentum was not easy to halt, as you claim.)
UK National Army Museum said:The force of the British charge smashed through the French infantry. But the lack of control meant the British heavy cavalry rode too far and were eventually destroyed when French cavalry counter-attacked.
Lieutenant René de Montmorency of the 21st Lancers said:They were as thick as bees and hundreds must have been knocked over by our horses. My charger – a polo pony – behaved magnificently, literally trampling straight through them.
A polo pony - a polo pony! - trampled straight through hundreds of infantry who were "thick as bees" at Omdurman. This is why it pays to be thorough when you're looking for historical accounts, and make sure you have the whole picture.
UK National Army Museum said:Half the 447 horses on the charge were also killed or hurt. But the lancers regrouped and proceeded on foot, using their carbines to drive off the enemy.
Just a bit more proof there that your numbers weren't researched heavily enough. The official count from the National Army Museum is 447 horses, which means 447 riders, which means at 73, only 16% of the Lancers were wounded or killed in the charge.
Wikipedia said:It was there that the full regiment charged with lances in the classic cavalry style during the Battle of Omdurman in September 1898. Of less than 400 men involved in the charge 70 were killed and wounded[3] and the regiment won three Victoria Crosses. These three were Private Thomas Byrne,[4] Lieutenant Raymond de Montmorency[4] and Captain Paul Kenna.[4] This spectacular encounter earned considerable public attention and praise for the regiment, though it was also criticized as a costly and unnecessary anachronism - since the 2,000 Dervish spearmen dispersed by the 21st Lancers could have been destroyed by rifle fire with few if any British losses.[3]
Two things to note here. First, that this front-on charge, lance to foot, was "in the classic cavalry style". Second, that the regiment was praised for how it conducted itself during the charge, and that the criticism came because it was unnecessary, not because it failed. It didn't fail. 2,000 Dervish were dispersed. It did its job. It was merely stated to be costly because ~70 Lancers were made casualties, and arguably a line of infantry could have done the job with less losses. If you can disperse the enemy with zero losses, a single casualty out of 5,000 would be considered costly.
Private Wade Rix of the 21st Lancers said:As my horse leapt in among them, my lance entered the left eye of a white-robed figure who had raised his sword to strike. The impact shattered the lance and I quickly drew my sword as another man pointed his flintlock. I struck him down and blood splattered his robe.
The private's horse "leapt in among them".
theroyallaners.org said:The regiment fought its way through the packed enemy and moved away, dismounted and opened a withering fire using carbines, forcing the Dervishes to withdraw.
I'm not saying the gunfire from the Lancers didn't contribute to the Dervish withdrawal, by the way. I'm merely saying that the charge phase was a tactical success, despite overwhelming differences in numbers.
Andrew Knighton of warhistoryonline.com said:Though three men were awarded Victoria Crosses for courage in the action, and it was praised in the press, in reality it was a needless waste of lives.
It was criticized because it was unnecessary, not because it failed or was executed in an improper way.
Micheal Chimaobi Kalu of warhistoryonline.com said:After a bloody clash, the lancers, who had not experienced a fight before then, successfully drove the Mahdists back. Winston Churchhill, then a lieutenant, was a participant of this charge.
Although the action of the 21st Lancers was seen by some as reckless, there’s no disputing the fact that in the event of their action, the power of a cavalry charge was still useful.
1. These men did all this despite having no combat experience, such is the power of the charge.
2. It was, again, viewed as reckless. Not as a failure.
3. "Still useful", coming from someone whose job is to research military history and write about it, suggests that he's well aware this was the normal way to conduct a cavalry charge throughout history.
Mark Simner of historynet.com said:Unbeknown to the British cavalrymen, the khor was both wider and deeper than previously thought. If this was not bad enough, as the lancers drew closer to Abu Sunt they suddenly saw a number of warriors and banners unexpectedly rise up from the ground. The position was more heavily defended than anticipated, with over 2,000 Mahdists now awaiting their attackers. The lancers were galloping directly into what was later learned to be a carefully laid ambush!
A key thing to note about this whole affair is that the difficulty was not because they were charging packed infantry head-on. There were a number of things contributing, such as the fact that it was a damned ambush and the fact that it all took place in a khor, both wider and deeper than expected. A khor is a ravine, which means they were charging through water. This is a massive mitigating factor on a charge if it's deep enough.
Mark Simner of historynet.com said:The entire clash of arms lasted less than two minutes, and resulted in the loss of one officer and twenty men of the 21st Lancers killed, while another four officers and forty-six men were wounded. Of the 320 horses engaged in the charge, 119 had been either killed or wounded. Yet the charge had achieved little, and is largely viewed as a near disaster and a terrible mistake by military people of the day and historians ever since.
Oh hey, I found your source. And notice again how he says "near" disaster. When he says "achieved little", I presume he means strategically, though it's unclear as he doesn't state that the Dervish were scattered, either. Could be he legitimately thinks the charge failed, but as various other sources above have told us, that would be inaccurate.
-----Now people who believe this myth of course have to somehow explain how can you collide horse on to a pike planted in to the ground and not impale it, and they usually do so by saying that horse is "heavily armored".
That reminds me. You never addressed my math.
You have a spear made of white ash. Spear shafts were commonly made of rather sturdy ash wood. White ash - the strongest type of ash - has a parallel-to-grain compression strength of 7,410 pounds per square inch and a perpendicular-to-grain compression strength of 1,106 pounds per square inch.
Now let's look at the average war horse. We can surmise that on the smaller side of the estimate, war horses weighed around 1,700 pounds, plus another 50 or so for their barding (which protects them from thrusts, by the way!). That's 1,750 pounds or 793.78 kg, and that's not even accounting for the rider. Just the horse. The average horse bred for long-distance running (which war horses often were) clocks around 40 miles per hour, some faster. This equates to 17.8 m/s.
Stop distance must be determined. Let's assume the horse running through is the stop distance. There are no hard numbers on this, so let's just assume it moves about two ranks past the man whose spear hits him. (Before you protest, the shorter the stop distance, the greater the impact.) With a braced stance, we can put the "depth" of a footman at around two and a half feet, maybe three, plus another five feet or so for the amount of spear out in front of him. That's a total of 11 feet or 3.35 meters.
Now we can plug these values into the equation for solving impact from a horizontally moving object: Work = Kinetic Energy is Force × stop distance = 0.5 × mass × velocity^2. Therefore, so F = (0.5 × m × v^2) ÷ d. For us, that's ((0.5 x 793.78 ) x (17.8 ^ 2)) / 3.3, which equates to 37,537.5 Newtons of impact force, or 8,438 pound-force.
What this means is... If you managed to point the spear directly at the horse and hold it perfectly steady, the spear might not break from the weight of one horse and its panoply alone. If you're lucky. That's assuming you can keep it in your hands with 8,438 pounds of force trying to drive it through your hands and into your hip (the high end of the normal range for handgrip strength in a 25-29 year-old male is about 126 pounds). If you're just a little shaky and that spear pushes up, down, left, or right at all, it's going to snap no questions asked.
My explanation is in the numbers. Your explanation seems to be drawn primarily from - in a grand stroke of irony - video games like the earlier Total War titles, which provided an increased damage value to braced pikes to explain their effectiveness against horses. If I'm not mistaken, Thrones of Britannia corrected this by making horses reluctant to want to collide with spears, which would have been the more historical reason frontal charges against pikes failed.
Bannockburn, one of the most famous examples of pikes vs. cavalry, tells it as such:
The Scots began the second day of the battle by holding mass. Edward supposedly delayed the engagement, initially confused by the disposition of Scottish infantrymen wielding long spears. Nevertheless, he still ordered an attack against the Scots with his cavalry. Upon the initial charge, the English avoided the anticavalry ditches, but they were unable to penetrate the Scottish lines. After multiple cavalry charges failed to break the Scottish defenses, Robert began to move his infantry forward. As the English backed up, the ditches hindered them after multiple horsemen fell in and could not escape. The battle transformed into an all-out rout, with many of the English being slaughtered. Edward himself barely escaped.
Notice that if the charge was delayed, it was because Edward was trying to divine the purpose of the massed formation, not because it was considered a death sentence to charge.
Notice that Edward II, then a veteran military leader, ordered the charge anyway.
Notice that it failed because they were unable to penetrate the Scottish lines. This must mean that the goal was to penetrate.
Notice that multiple charges were attempted. If the first impact slaughtered half the horses, how or why would this be possible?
Notice that after many charges, the cavalry was able to be pushed back.
Notice that it was the ditches, which they hand initially avoided, that killed most of the English cavalry. Not the braced pikes. It wasn't until the Scots started advancing and bullying the horses, then lacking forward momentum, into the ditches that it started to get shaky for the English.

Reality is of course that 99% of the horses that did charge infantry did not had any armor protection. You can look Bayeux tapestry for example if in doubt.
Please don't throw out percentages from nothing. The evidence doesn't exist to prove that 99% of horses were unprotected throughout history. The data is insufficient. Beyond that, horse armor existed before Christ, why would you claim that a full 99% of all horses to ever execute a charge had no armor? There's no reasoning behind that claim, particularly when you realize that High Medieval knights - who regularly barded their horses - were the ones who preferred the charge most.
But that's only part of the reason whole horse as a battering ram myth falls apart. Other part is that while you can put armor on a horse, it's very difficult to protect horse legs. They are for most part unprotected:
Here is a horse running at 38 MPH. Warhorses, it's suggested, went as high as 40 to 43. How easy do you reckon it would be to hack its legs at that speed? Even if we don't account for the vertical motion of the legs, how easy do you think it would be to stand your ground and piece the headlight of a car speeding towards you at 40 miles per hour without dying? Nevermind that if you're armed with a spear, as you keep saying makes you invincible to horses, you'd be piercing. You'd have to put the head of a spear on a constantly displacing limb that's about what, 3-4 inches wide? You'd have to do that while it's advancing towards you at 40 miles per hour and the ground is shaking beneath you.
And then you'd have to pierce the bone, which is another thing I'll address.
And computer games unfortunately add to the mess. Way too many people here base their believes on what they learned playing the Total War games. Hence inability to realize that "charge" in real world literature does not mean head on collision and real soldiers, horses and weapons does not have "shock attack value" and "hit points". Horse with broken leg is written off and it's HP is not 90%.
A horse's hit points in a video game are a mechanical representation (granted, not a scientifically accurate one) of the size of a the horse. Warhorses were big, powerful creatures with dense musculature and dense bones sufficient to carry loads of nearly one ton. "Shock attack value" is derived from the horse's impact force. Again, it's not mathematically sound, but it's a representation. My point is that these values aren't just imagined from nothing, they represent science in a shallow, game-balancey way.
All that said, I don't take my stance from video games at all. Everything I've argued with has been scientific. It would not be half as easy to kill a horse as you think, barring a lucky stab to just the right spot. It would not be as easy to maim a horse as you think, barring hamstringing it, which would have to be done after the charge while it's stationary. The only time a horse would have been a logical target was when it was stationary. This is exactly why your theory of "they ran into melee range, stopped, an then poked the footmen to death" is so ridiculous. You're essentially arguing against yourself with these most recent posts. This fellow explains it quite well.
