That is rather tragic to say the least . I still remember the Lord's test against India in 2007 when England were a wicket away from clinching the first test . But rain poured down for the next one and a half days , it not only saved India the test match , but also won them the series .
Actually Vaughan went a long way to gifting India the series with negative tactics. 1st Test at Lords, England were in a good position to push onwards for victory but Vaughan was typically overcautious and wanted to reduce the runs to over/time equation further ie he was more worried about the outside chance of them winning than he was about precious time for England to force victory.
England vs India (Lords, 2007)
England 1st Inns 298
Strauss 96, Vaughan 79. Sreesanth 3/67
India 1st Inns 201
Jaffer 58. Sidebottom 4/65. Anderson 5/42
England 2nd Inns 282*
Pietersen 134. Khan 4/79, Singh Jr 5/59.
India 2nd Inns 282/9
Khartik 60, Dhoni 76no. Tremlett 3/52
* England were 251/5 at the end of over 66 in the 2nd innings, a target of 349 for India to chase with five wickets to add quick runs. Pietersen fell at the end of the 77th over, a full ELEVEN overs later with just 24 runs having been added. England extended their total by 31 runs over those last dozen overs or so, but in truth it was just valuable time wasted with no guarantee there'd be enough time for the precious runs to overs/time equation remaining the same with weather and light always a worry.
I'm not just saying that in retrospect, I thought it at the time. Maybe pushing on quicker would have ended the innings up to 20 runs worse off, BUT in a three Test series you can't assume you'll get many good chances to win and be on top and that proved England's best and only chance which they squandered. Ended up with Vaughan himself bowling four overs for 18 runs at the end, a bit more urgency when batting and England would have been bowling the same situation a few overs earlier with a pace bowler.
It's little wonder Vaughan never beat India, Pakistan or Sri Lanka in a Test match as captain in ELEVEN attempts. You can look at raw stats and say he was "great", but he wasn't. FOURTEEN of his 26 wins as captain were over Bangladesh (4) and West Indies (10), with a further six over the kiwis. Sure he won the Ashes with a very good side against an excellent side, but that was only by 2-1 and two runs and three wickets win margins in the Tests themselves. He grabbed a fine win in South Africa as well, but that was the peak of it.
Vaughan (captain)
vs AUS/SAF : P17 W6 D5 L6 (Won 35.3%)
vs PAK/IND/SRI : P11 W0 D7 L4 (Won 0.00%)
vs NZE/WIN/BAN : P23 W20 D2 L1 (Won 86.96%)
Six wins in 28 Tests against the better sides says it all, but that is covered up by playing West Indies in about 1/4 of his Tests and HALF his Tests as captain were over sides England beat pretty regularly (these days, West Indies were a force up until around 2000)
