The Tigers also missed the service of extra pace-bowlers as they took the field only with one pacer in the playing XI.
Kyle Mayers, the 28-year-old left-handed batsman, registered a double ton on debut to guide his side to the record-breaking win.
This was the first time a team had won in Bangladesh chasing a target of more than 350 runs. Also, this was the first instance of a debutant hitting a ton in Test for the West Indies after Kirk Edwards who did it in 2011 against India.
And Mayers partnered Booners in the fourth wicket stand to post 216 runs on the board, which proved to be a decisive partnership.

The West Indies scored 395 for seven in 127.3 overs. For Bangladesh, Mehidy Hasan Miraz bagged four wickets conceding 113 runs, the best bowling figures for the hosts in this innings. But it was not enough for them to take a lead in the two-match series.
Earlier, in the first innings of the match, Bangladesh posted 430 riding on the maiden Test 100 of Mehidy (103). Shadman Islam (59) and Shakib (68) also hit a 50 each.
Jomel Warrican was the best bowler for the tourists, scalping four wickets while Cornwall took two.
In reply, despite some good batting displays from captain Kraigg Brathwaite (76) and Jermaine Blackwood (68), the West Indies managed to score 259 runs in their first innings after losing last five wickets in six runs.
For Bangladesh, Mehidy bagged four wickets while Mustafizur Rahman, Taijul Islam and Nayeem Hasan took two wickets each.
