Every Army officer should read Spencer Fitz-Gibbon's
Not Mentioned in Despatches. It is the single best battlefield analysis I have read to date and breaks down a unit level battle to its component parts.
The author shows conclusively that the CO overplanned the attack, tried to overcontrol the attack, and just plain executed a clumsy action. He was rude and dismissive of his subordinates, and when his bad attack stalled and was in danger of failing, he acted stupidly and was shot and killed. For his actions, he was awarded the Victoria Cross....
Fortunately, his DCO was a far better officer and was able to rescue the situation, reorient the battalion, and carry the day.
There were 6 unit level engagements in the Falklands War; Goose Green (2 Para), Mount Harriet (42 Cdo), Mt Longdon (3 Para), Two Sisters (45 Cdo), Mt Tumbledown (Scots Guards), and Wireless Ridge (2 Para). The first was a lone attack driven by political imperative (as all acts of war must be), the middle three where part of the break-in battle at Stanley by 3 Cdo Bde, while the last two were executed as a breakthough to Stanley itself (I believe this was commanded by 5 Bde - can't check my sources now).
All of these attacks were conducted at essentially 1:1 odds, which puts paid to the silly myth of "must attack at 3:1" that we continue to hang on to. Suppression and, ultimately, shock are the key and history shows that small assaulting elements are successful against a larger enemy who is in shock. There is some clever deception and manoeuvre in these attacks, and they are all worth pulling apart. One featured the British stepping into a minefield, which forced some hasty reaction on the fly.
MGen Thompson, Comd 3 Cdo Bde, said that after Goose Green, all attacks were conducted at night because they did not have enough artillery systems to adequately suppress the Argentine prepared positions. This goes to show that manoeuvre and firepower is not a dichotomous relationship, and the ability to mass accurate fires quickly on the fly is essential to support good manoeuvre. The German break through at Sedan in 1940 was supported by essentially every German bomber in theatre.
The Argentines also fought well; even poorly led conscripts fight well from hardened positions with sited crew-served weapons. None of those battles were walk-overs. The Argentines were dreadfully led though, and while they were capable of defence, they lacked the leadership to challenge the British through aggressive patrolling and countermoves. This should be part of our calculus in the attack; what's the enemy likely to do?
The Battle for Stanley is instructive in a few regards. The first night's attack on Stanley at Mount Harriet, Mount Longdon, and Two Sisters was essentially a broad front attack by a Brigade - all three objectives were hit almost simultaneously. Thompson has been asked over the years as to why he didn't conduct a "pencil attack" to break through the crust of the Argentine defensive position with one unit and push other units through the breach. He said that when you look at the ground, Mt Longdon in the North was simply too dominant of a feature to be ignored.
His concept was to attack "three up" and to figure out where he best opportunity to exploit was the next day. These attacks were all "silent" - conducted at night with little preparatory fire - because he did not have enough artillery ammunition or guns to properly suppress/shock the Argentine positions. The fighting took longer than expected (further proof that the Argentines weren't terrible), and so exploitation wasn't possible and the Brits had to re-cock to conduct further engagements the following night.
Finally, these were all deliberate attacks; 3 Cdo Bde had a week to conduct reconnaissance from its positions at Mount Kent/Bluff Cove. Thompson wanted to attack earlier, but was told by his boss to wait until 5 UK Bde got established. This was a good example of inter-service politics - there was no chance the British Army was going to let the entire ground fight be conducted by a Marine Brigade.
The so what out of all of this?
1. Ground always provides options and limitations.
2. Small units (companies and platoons) win engagements through aggressive patrolling and closing with the enemy after suppressing/shocking him through fires.
3. Larger units (battalions and brigades) win battles by figuring out how to shock the enemy and exploit the opportunities presented by small unit engagements. These commanders have to understand how engagements are unfolding, recognize what is happening vis-a-vis the enemy, and be capable of adjusting the plan on the fly. They must not try to control the battle, and they must be comfortable with the uncertainty involved in "fighting on the fly."
